This is a new Windows Server 2012 R2 Essentials setup, This server is basically running everything on the network as you would probably expect with an essentials setup, all the client PC?s are running Windows 8.1 Pro with Update 1 and are fully patched.

It is a pretty much out the box essentials setup integrated with Office 365 and Windows Azure (For an additional offsite backup) I have added a few additional group policy settings for mapping Network Printers, the Desktop Configuration (e.g. to disable the tablet lock screen) along with opening up open some ports on the client PC?s firewall as required for Sophos Endpoint Security to be deployed.

This has been running for around a month now with only one re occurring issue, randomly when users log on to their PC Windows asks the user to enter their Domain Credentials:

?The system cannot contact a domain controller to service the authentication request, please try again later.?

This happened randomly to one user on the Monday after I had set the new network up, however this week its happened to that user again, along with three other users now. It appears once the user has logged on Windows is forgetting the users Domain Credentials:

This basically means folder redirection does not work, no files can be accessed on the server, no printers, about all the user can do is access the internet.

When this has happened adding the user?s Domain Credentials in the Credentials manager appears to have fixed the problem, however im concerned about it happening again, and to other users.

Basically I?m wondering if anyone has any idea what might randomly cause this, or how I could go about troubleshooting the issue? it really does appear to be very random when this happens.

Thank you!

network settings...

 

do an ipconfig/all on both the server and the client workstation and post them here.  if you don't want them posted pm me. 

 

 

 

99.999% of the time it is an improper configuration on your network card settings, pointing to a dns server out on the web and not the dc as your dns server.  also your server can only be the dns, there cannot be any internet dns servers setup on your nic cards of both the server and the workstations.  the server needs to point to itself, and the workstations need to point to the server for all dns resolution.  the dns service on the server will determine where to send the clients/server when it does a look up.

 

.001% of the time there is something going on and we will need to look at the eventlog to determine.  But being that an improper configuration is the most common cause by a landslide, lets look at your network card configuration on the computer and server.

I have sent you a PM with a full ipconfig from the server and a client PC

 

Thank you in advance for any insight in to this issue.

Domain controller should not be dhcp, I think you will find issues in the log regarding this.

When doing a dc promo, or running the wizard, I am positive it throws up a big warning about dhcp and forces you to manually set the address of the nic before continuing.

I don't think the dns service likes this either and you may see log entries the dns event viewer.

Thanks for the advice sc302, I had set the server to always be assigned the same IP address by the router, however that clearly causes issues!

Everything appears to be ok since manually assigning the IP address, and ensuring the servers DNS was set to the same as the servers IP address.

A newbie mistake I have certainly learned from, thanks once again :)

    • Microsoft announces multi-year partnership with AMD for future of Xbox consoles and hardware

      By Ringo Tanner · Posted

      Sales don’t mean anything at all??? How many copies of FH5 did Microsoft sell on pS5? The number PS5’s impact those sales. What cheating is there on PS? A small amount of users spending money on KVM setups? PC gaming cheating is 1000x worse than any console gaming cheats. Joe user can easily buy full on cheats for PC games with full on easy to use gui’s for the cheats. Those websites brag about how many days they have not been caught. There is nothing like that for console gaming. Apparently you know nothing about nothing.

      Console game sales still make more money than PC game sales. Both behind mobile game sales. Both Microsoft and Sony are making big money off of the games Microsoft is porting to PS. Those 75 million PS5’s are making an impact. There is a big market for console gaming and only Xbox console sales have suffered. The PS5 is on track to out sell the PS4. Yes Sony is porting their games to PC 18 months on average after they hit the PS5. Most console gamers want nothing to do with PC gaming especially Windows 11.

      Oooh so that’s why. I was about to say there’s zero financial incentive to stop releasing songs for an EXISTING platform, but now I understand. Pathetic. I was planning on buying this game for VR2, but I guess I’ll just stick with Synth Riders then.
    • WD SSDs still block Windows 11 24H2 download and installs, Microsoft may be guilty too

      By hellowalkman · Posted

      WD SSDs still block Windows 11 24H2 download and installs, Microsoft may be guilty too by Sayan Sen Microsoft has been slowly lifting several upgrade blocks for Windows 11 version 24H2, the 2024 feature update for Windows 11. For example, the most recent one was related to browser compatibility, and it was removed last month. This safeguard hold was lifted about a week after the company released the update such that it was available for download to everyone. However, there are still plenty of other compatibility blocks that are still in place. These include ones for Dirac Audio, sprotect SYS driver conflict, among others. Meanwhile, it looks like there is also an upgrade block on certain Western Digital SSDs that prevents them from getting the feature update. While Microsoft, or at least Windows 11, seems to be blocking the upgrade, the issue is not documented on the tech giant's health dashboard website alongside the other entries. The typical "What needs your attention" message box pops up indicating that the WD NMVe SSD in the user's system is the issue. It says: Thus, Windows thinks the WD drive in question is not compatible with the Windows 11 2024 update. As it turns out, the problem, one related to Host Memory Buffer (HMB), has seemingly already been fixed back in October 2024 with a new firmware update. However, Windows does not seem to deliver the correct link to download the update, which means users may still be unable to download Windows 11 24H2 on their PCs. A Reddit user found out that they were able to bypass the block by manually downloading the firmware from the SanDisk official support page for the corresponding drive model. They write: Thus, in case you happen to own such a disk, make sure to head over to the SanDisk Dashboard website here. It provides support for the following models: WD Green, Blue, Red, WD_BLACK, SanDisk SSD PLUS M.2, Extreme M.2, Extreme Pro M.2, Ultra 3D. You can find the instructions for updating firmware at this link. Source: Microsoft forum (link1, link2), Reddit
