Can't see 2008 R2 server, but can see clients?


Recommended Posts

Hi Guys,

Hope you can help with this one. I'm sure it's something stupidly obvious, I'm just not sure what!

I have a Windows Server 2008 R2 machine sat on my home network - it's a test box pretty much that I use for messing around with. I've enabled "Network Discovery", ensured the UPnP service is running, and turned the windows firewall off, but I simply can't see the machine on the internal network from any client machines when you click Start -> Computer, and choose Network on the left hand side. If I open up a command prompt and ping via hostname - it works fine, I get a response. If I try and connect to it via hostname in Windows Explorer by typing \\myhomeserver\ - I get an "You do not have permission to access \\myhomeserver" message. However, if I connect to it via IP Address \\192.168.2.3\ then I'm prompted for a user name and password and all works perfectly fine.

The other way round, however, I can see the clients on the network from the server without any problem at all!

I'm sure it's something really trivial, I just don't know what. Any suggestions much appreciated!

Are they on the same domain/workgroup?

Have you recently had another OS installed on the network with the same hostname before installing 2008 R2? Might need to do ipconfig /flushdns and/or arp -d on the clients

In Server 2008 R2, in Network and Sharing centre, Make sure that the right options are enabled to allow clients to access the server.

Make sure that the Network is not set to Public (Should be Work/Home - not sure if you even get the Home option but you get the idea).

On the server 2008 R2 machine is the network its connected to a Public, Home or Work network?

It's connected to a Home/Private network

Are they on the same domain/workgroup?

They are - not using a domain here, but using the standard "WORKGROUP" workgroup.

Absolutely nothing on the network using the same hostname as this one, and never has been.

In Server 2008 R2, in Network and Sharing centre, Make sure that the right options are enabled to allow clients to access the server.

I've just triple checked - and they are definitely all set so that the machine is discoverable.

an alternative would be to install the DNS server application and have all the clients get their DNS from that server.

I don't REALLY want to do that as the machine won't be on 24/7.

Some additional info - I just tried connecting to a shared folder using \\myhomeserver\testfolder - instead of just \\myhomeserver. This seemed to get a little further - instead of just flatly denying me entry, or timing out, it just displayed an endless number of password dialog boxes, which just kept popping up over and over and over again....

I would say adding DNS to the Server and having all the clients come from that DNS would be easiest. It "should" already work the way you say you have it set up, but DNS isn't difficult.

"ensured the UPnP service is running"

Has nothing to do with network browsing.

Your 2k8 server should win the election, but maybe not? You can view which machine is the master browser for your segment with a simple nbtstat -A IPaddress

example

C:\Windows\System32>nbtstat -A 192.168.1.6

gig:

Node IpAddress: [192.168.1.100] Scope Id: []

LOCAL <1D> UNIQUE Registered

LOCAL <00> GROUP Registered

As ease of creating the browselist, even thought you can have multiple workgroups listed, and this has nothing to do with file sharing btw.. it will be easier to maintain the list if you only have 1 workgroup running local. So as stated make sure your 2k8 box and other machines are all in the same workgroup -- this will speed up population of the browselist.

BTW you might also want to make sure that only 1 box on your network can be the master browser, if you turn your machines on and off all the time.. you can do it with a reg entry - or you can just disable the computer browser service on any machine you do not want to be the browse master -- ie leave this service running on your server.

btw -- simple netview will show you the machines listed in your network browse list

C:\Windows\System32>net view

Well if you have your machines on and off all the time, then yeah its quite possible for you to have some issues with the browselist - since first box on will start to maintain the list, then next box comes on there will be an election, etc. It should all work itself out, but right after you turn boxes on or off the list might be out of date, it can take quite some time for the browselist to get into sync, upwards of 45 minutes sometimes. Read the docs I linked too.

on a side note --- I for the life of me can not understand why users are so keen to the browselist, don't you know your computers name -- then just use that.. as to your access denied when using \\name Do you have netbios enabled?

example on your 2k8 box

I know going from my Win 7 to Win XP with it if I didn't add the folder after it wouldn't connect. Plus off-topic, I have a Belkin N+ with a USB port for NAS and I can't ever access it, I get the same continuous login as you are and I can't figure out what the UN/PW is/could be a bug?

As to access your usb plugged in device.. Are you using the storage manager software that comes with your router for that purpose? How are you access it -- you need to know the device name for the share ie \\ipaddressoffyourrouter\devicename if your just doing \\ipaddressofrouter that might be is sharing bug on their part, etc. From the manual it does not mention username, etc.

edit: As to access \\computername vs \\computername\share -- yeah its going to depend on the permissions you have setup.. So yeah its quite possible to have issues connecting to \\computername but be able to access \\compuername\share -- depending on on how your sharing and what permissions you have setup and what account your wanting to use, etc.

You can run into problems if your machine auths with the currently logged in account getting access denied, you may need to use other creds to auth, etc. etc.

I remember when I did a clean install and used the storage manager when I first bought the router it did work, but it hasn't in a long time, but I have done many reg hacks and things to my Win 7, plus I also moved up to the SP1 Beta. Its not a huge deal, the drive I was using is actually hooked to my PS3 and just has movies on it. I plan on using another drive at another point. Its all on my entertainment stand so its easy to get to. I have 2 laptops and a desktop in my kid's room so its really not a big deal, I was just mentioning it. The devicename and all that is known but it keeps asking for a stupid UN/PW and I can't access it because I don't know what it is. Also another off-point, the workgroup the router share is listed as is Belkin_N+ (which is of course, an illegal workgroup afaik and windows agrees with me)

Managed to solve the problem guys. It would appear at some point in time as part of my experimenting, I managed to install Hyper-V. As soon as I removed that, all now starts to work :)

I don't see what Hyper-V would have to do with it. I would put it down to something else that you did (or a certain amount of time has gone past for the problem to resolve itself), and uninstalling Hyper-V is a coincidence.

HYPER-V installs virtual switching drivers and stuff. so if you dont configure hyper-v right all your network settings would get screwed up.

Thats why I like VMWare. Install it, take snapshots along the way of experimenting and if you screw it up, 3 seconds to revert to an older snapshot

This topic was dead and I still was having issues, but I figured since I resolved my issue I would explain. Apparently since I'm using Win 7, it defaults the NTLM security to requiring 128 bit encryption. My NAS is a cheapo and doesn't have the security. Once I did this it worked -> Control Panel - Administrative Tools - Local Security Policy - Local Policies - Security Options

By default Windows Vista and Windows 7 sets the policy to "NTVLM2 responses only". Change this to "LM and NTLM ? use NTLMV2 session security if negotiated".

my SMB/NAS server worked after changing the option!

I followed this guide:

    • I actually got to use one of those so called "backup codes" once. It was for a customer, I choose the backup code option, and by the grace of god, they actually hade them printed out. Imagine my surprise, when after using the backup code, Google then told use we had to enter a code they just sent to the gmail address we currently did not have access to. I was not amused, Google backup codes should be the end all get out of jail free card, because you had to have access to the account to even get them.
    • On the topic of being locked out of a service. Recently two different friends of mine got locked out of their Google accounts. Both were hack attempts and one of them is waiting 30 days before he can get back in. He had backup codes and MFA but not a passkey. It was a browser token hack. Anyhow he has to wait 30 days for the dispute or whatever to end. The other person only had a password and is screwed losing all of the email, docs and years of photos. Google won’t help her at all. Her fault because she had no backup/recovery setup. Enable passkeys if possible. Also do NOT use browser based password managers. If using a cloud service make sure it is one you can fully sync to one of your devices so you can back it up. Like a PC or Mac with some backup drive plugged into it. Google is the worst to use IMHO. You can’t sync your photos at all. You have to use the “Take Out” service which is manual and takes days. That service strips the meta data from your photos. Also Google Docs synced to a device are useless without a Google accounts. MS Office/Libre Office is not going to open a link to a Google doc to a dead account.
    • Why you need to take back control of your synced passwords and how to go about doing that by Paul Hill Credit: Pixabay Last month, when Google decided to introduce daily and weekly caps for Gemini, it reignited an anxiety of mine, that you can’t really depend on service providers to maintain features forever, and it got me looking into free software (as in freedom) in other areas too. One app I quickly came across was KeePassXC on desktop and KeePassDX on Android as an alternative to password manager lock-in within the Chrome or Firefox ecosystems. I personally like to switch around with browsers, and using either password manager is inconvenient, so something like KeePassXC was interesting to me. The main issue with it now is syncing; I was not sure how to do that. After a bit of research, I came across Syncthing, a tool I was vaguely familiar with but had never used because it seemed complicated. However, I was completely wrong, and honestly, I think everyone should use it if they use multiple devices. It essentially lets you share folders peer to peer across all of your devices, no cloud services that you don’t control necessary! And it was fairly simple to set up, if not a bit clunky. Since setting it up, I’ve also started using Syncthing to back up other apps too, so don’t think it’s limited to just saving password databases. You can use it for pretty much anything you use Dropbox or Google Drive for. Before continuing to talk about those apps a bit more, let’s walk back a bit and talk about browser sync. Ever since the late 2000s and early 2010s, really, since we have been using smartphones, browser sync has been a necessity of life. I don’t know about you, but I have hundreds of passwords saved. For the most part, they’re all unique, so I don’t remember them and rely on software to manage them for me. Until recently, I’ve relied on password managers in Chrome and Firefox, but what I always found annoying was that it can be hard to transfer them between browsers. Sure, on Windows it is simple enough, but on Linux, exporting bookmarks has been temperamental. It works OK nowadays, but not too long ago, Chrome required you to enable exporting passwords in chrome://flags. The situation is even worse on mobile; there is no exporting or importing of passwords of any kind. You literally have to do it on a desktop, which is incredibly annoying in our mobile-first world. Sync also lets us take out bookmarks, history, tabs, and autofill data easily. To enable sync, it’s just a matter of signing into the browser once, and it handles the rest. It’s nice and easy. Obviously, all this has some issues, including those I’ve outlined above about it being hard to transfer data between browsers, but also things such as account suspension, lost account passwords, and other lock-in mechanisms, such as passkeys, being tied to a specific browser. On a sidenote, I have just removed all of my passkeys because they can make it harder to move browsers. I think the biggest threat to your synced passwords, especially if doing this with Google, is having your account suspended. I don’t ever expect mine to be suspended, but you do hear horror stories on Reddit where people lose access to their Google accounts. Imagine if you have hundreds of passwords, then suddenly lose access to them because Google froze your account, what would you do? So yes, it can be nice to use these syncing services for their convenience, but they also have risks. You may have seen me going on about free software quite a bit in my editorials. It’s essentially a concept championed by the Free Software Foundation. It’s software under particular licenses that grant you four freedoms: run the program for any purpose (0), study and change the source code (1), redistribute copies to others (2), and the freedom to distribute modified copies to others (3). For example, if there is an app I use and one day it gets abandoned by the developer, I can keep running it or even clone the software and continue developing it. Look at the myriad of cool services Google has run over the years before killing them. You can’t take the source code for those because they are proprietary, for the most part. Both KeePassXC and Syncthing are free software, so I get the freedoms listed above. In my use case where I’m syncing a database full of my passwords, I also get proper ownership over my data, there is no losing access to the database due to a frozen account, I can access the code of the tools I’m using, and I can get support from real people online if I run into issues, rather than having to consult a vague help page from an opaque company. With the KeePassXC password manager, you create a .kdbx file, which is what will be synced between devices. KeePassXC has cross-platform apps and also has browser extensions so that the browser can fetch passwords from the database once it is unlocked. Meanwhile, Syncthing is a peer-to-peer file sync tool where you can select folders to sync between your devices. Just pop files in the folders you choose, and then they will be available across your other devices whenever they come online. Syncthing is resilient as it works over both LAN and the internet and only ever sends content between your devices, never to a third-party server somewhere else. By combining these two pieces of software, you can essentially replicate the browser sync functionality. I have had a weird, conflicting issue where a new file is appearing, but it doesn’t seem to be impacting my main password database, which is updating between devices just fine. If you want to get a setup similar to what I have, you will need to go here to download KeePassXC for your computer. Once you have that, you will need to download your passwords from your web browser to a CSV file. In Chrome, you can type chrome://password-manager/settings into the URL bar, and you should see an option to download your passwords under Export Passwords. This will give you the CSV file you need for importing into KeePassXC. If you use a different browser, just use a search engine and type “browser-name export passwords” and muddle along. In KeePassXC, you’ll want to press Import File from the home screen, select the CSV file, and create a new database from it. On one of the screens of the wizard, there will be a Title field with a drop-down selected to none. Change this to Title and continue. You’ll select a name for the database, the encryption level (the defaults are fine), and then you will pick a password. I would choose four unrelated words that are easy for you to remember, as you’ll be typing them fairly often to access your passwords. When you have all your passwords in your new database, you will want to set up the browser extension so that your browser can fetch passwords from KeePassXC. Rather than explain how to do that here, refer to KeePassXC’s guide on how to set it up properly. Once you’ve got that set up, you want to install KeePassDX on Android. You can grab it on the F-Droid store and the Google Play Store. For iPhone users, there are other .kdbx-supporting apps, but I haven’t tried any of them, so have a look around and use what suits you. Once you have that done, you will want to install Syncthing on your computer and find a third-party app for your mobile device. On Android, I use an app called BasicSync; there are also options for iOS, but again, I’ve not tried these. Once you’ve got SyncThing, you’ll want to set it up and connect all of your devices together and share a folder between your gadgets. PCWorld has a good tutorial on setting up a synchronized file between your devices using SyncThing. Once you’ve set it up, congrats, you’ll never have to touch that stuff again except for adding or removing devices. I’ll be honest, I didn’t particularly like setting up Syncthing. It didn’t take me a massive amount of time, but I think I had to check online because I found it a bit confusing. That said, I’ve had it running for several weeks now and never need to touch the Syncthing settings, so that’s very nice. I also mentioned a conflicting file. I’m not sure why this is appearing, but the main .kdbx file seems to be updating and syncing just fine. What’s nice is that both KeePassXC and Syncthing are free software, so they won’t just vanish one day; you can take the code and fork the project or use a range of alternative implementations that others have made. It’s also nice that it works over LAN, so even if your ISP is having problems, your passwords will still sync. One area where you will want to be a bit more careful with this setup is if you only have one device. I am OK because I have a computer and two phones, all synced up. If you just have one device, you will probably want to store a backup of your .kdbx file somewhere else. Obviously, you’ll also want to remember your password really well, too. If you get locked out, it's game over. Overall, if you want to take back control of your computing from big tech, taking control of your passwords is an important part of this. You don’t need to immediately clear out your browser’s password manager; try running KeePassXC and the password manager concurrently for a while to see if you run into any problems. If you do try this out, let us know some other creative ways to use Syncthing. I haven’t really come up with a solution about what to do with my bookmarks, for example.
