Well part of the problem if you only have 10 users is from your previous post machines had multiple IPs on the same network - so its possible they are making multiple connections.

You really need to clean up the wiring so that you each machine only has 1 IP (one wire) or wireless -- NOT BOTH and not multiple wired connections to the switch.

Remember you mentioned you have like 10 machines with 30 wires ;) I would suggest you CLEAN that up first no matter what you end up doing -- this may help your 10 limit issue.

Also you can disconnect users that are connected to the server without rebooting it.

Look here -- under sessions should show you all connections to that machine, and also open files, etc. Don't disconnect anyone that has open files -- but if you see a session and no open files by that user, you could disconnect the session to free up connections without having to reboot the server.

Budman,

Its not possible for me to do that because all the wires run through the damn ceiling. I disconnect one wire that goes into one computer and another one stops working. Its so damn confusing how its set up. Anyways were can i find that computer management thing with the sessions. Edit: found it. Now this is much better. Ok now when someone has a problem connecting I will check this and see how many pc's are connected. If there are less than 10 then something else is the problem.

Dude I don't care how hard you think it is, it needs to be FIXED!!! Your making harder than it really is -- does not matter where the wires go.. You have access to the end points (unless there is some other switch up in the ceiling ??).

So disconnect the wires on the computer sides.. So that they only have 1 wire connected to them.. Do this for all your computers -- once this is done then go to the switch and disconnect all the wires that don't have lights on.. Since they are not connected to anything!!

Now on each machine - disconnect the wire, go look on the switch which light went off?? Label this wire at both the computer and the switch.. When your all done -- pull out all the other wires ;)

Or if you want to leave them for expansion.. Once you have all the other wires labeled.. Disconnect a computers wire from both the switch and the computer.. Then use one of the other wires, then one at a time connected the unlabeled wires until a light comes on.. Now label this WIRE on both ends.

This should not take more than a couple of hours tops to do really!

But the FIRST step is to get the machines connected only once to the switch!! it would be faster if you got a wire tester to track down both ends of the cables.. But you can use what you have current to trace the ends of the wires.

It would also be easier with a managed switch, so you could look at mac addresses on each port, etc. But again -- you can do it with what you have in a few hours.

It NEEDS to be DONE!!!! having multiple wires that you have no idea where they go is just going to give you headaches the first time some machine is not working and trying to figure out if its the port on the switch, the interface on the machine, etc.. etc..

Do this clean up FIRST!!!!! It NEEDS TO BE DONE!!!

Why did I have visions of a token ring or bus network set up there when he said that once he "disconnect one wire that goes into one computer and another one stops working" *Shudders* lol Do you know about patching? I really dont understand whats going on in your enviroment at all now. Each computer will be patched into a wall socket perhaps right? That will then lead to a patch in your computer room wherever that might be and then from there to a physical port on a switch. Are you getting confused and thinking that each section of wiring is another cable :s

Its impossible for him to be unplugging a wire on a computer and have some other computer stop working :) Does not matter if there are patch panels or not.. There is NO way its token ring -- he posted what switch he is using ;)

But sure its quite possible for him to be unplugging the wrong cable on switch, etc. Or the one on the server (does it have multiple IPS) From your previous posts I would guess yes that a computer is using to access it with. Also from your previous posts you had 2 switches.. Did you atleast get it done to 1 switch??? Or do you still have 2??

Where I would start is disconnecting every wire on the switch that does not have a light!! That is when all PCS are on and working.. Now unplug one wire from a PC... If its stops working -- give it a second, or even reboot it -- maybe it was using that interface to access the server -- can take a couple of seconds to recover, etc.. once that machine is working on one wire. Remove the network card it was using from the machine if it was an addon card!! Always unplug the addon on card wire if there is one vs the built in one on the motherboard..

Once you have the computer working with 1 wire -- go to the switch and unplug the cable that does not have a light!! Repeat this process.. Leaving the server for last.. Once you do it on the server pc, you might have to reboot the server and pcs to make sure they now connect to the server on its ONE IP address..

Gawd I would almost be willing to come to your location to clean up this mess for free -- just so these threads would stop ;)

This is the current situation:

On the linksys sr2024 there are 16 wires connected, 14 have lights on. On the d-link dss-16+ there is 10 wires connected with 6 lights on. The most lights that should be on is 12-13 max with the 2 copiers we have that are connected to the network. So now I will start to unplug and see which goes were.

You can get rid of that one switch all together -- we went over this quite some time ago.. One is just a 10/100 while the other is a 10/100/1000 keep the gig one and get rid of the 10/100.

If I recall correctly you have enough ports for all your PCs (if they only have 1 wire connected) and a few extra for other network stuff like printers and or copiers, and the connection to your router with still room for growth... That sr2024 has 24 ports.. So 10 PC, plus router plus server is only 12 -- so you have 12 ports open for more pcs or other devices.. You do not need that other switch at all!!

Budman,

The question is, why is there 2 switches? There is plenty of space on the big one. There must be some kind of purpose that the other guy put 2.

I believe this is why Budman is suggesting over and over that you need to clean up the wiring jobs. It sounds completely botched up. At this point, I wouldn't bother wasting any more time by trying to guess why the previous guy did what he did.

We dont why your server has 2 NICs. Who knows why the Admin before you did that, or the weird ass cabling job.

Edit: I was under the impression you had already sorted all this out. You *Really* need to resolve any cabling issues BEFORE you start messing with clark connect or upgrading/migrating other systems.

There is NO reason why you would need 2 switches or multiple interfaces on any machine.. Other than the guy before you being an IDIOT is the only reason I can think of.

I would not worry why he did what he did, I would worry about getting it Cleaned up! If in the future you want to start teaming interfaces for failover or more bandwidth you can address that once you get the basics down, etc.

You have a XP box as your "server" with unmanaged switches for gosh sake, teaming interfaces for bandwidth or failover is so far down the road in improvements to your network its not even funny.

Lets get the basics down first.. Then you can move on to fancier setups later.. Once you have your network wiring cleaned up.. I would suggest you get your file server on server hardware (raid hard drives, dual power supplies, etc) with a server OS with the use of a domain vs peer-to-peer workgroup. Get your PCs off a HOME OS (XP home).. Then work on your backup issue -- $24K a year seems quite high for the size of your company.. Again for gosh sake your on a XP box for a server ;)

You could backup your 2TB of data for a LOT less!!

Then you could move to thinking about bringing other services like email up to speed? Not sure what your company uses now? What are they paying for it? Its clearly not housed on site.

Then you could think about using content filtering and or bandwidth management, etc. for your internet connection. Then you could worry about maybe moving to a managed switch..

These things are down the road -- for now lets get your network wired correctly so you understand what is plugged into what and how it works ;)

In a nutshell this is how your network should look.

post-14624-1257190538_thumb.jpg

Lets get it looking like this with each machine only having 1 connection to your network, and the one switch.. With you knowing which cable goes where, etc.. And then we can move forward.

All computers could be plugged into your 1 switch or the router switch ports.. Depends on where they are located, etc. The only reason I can think of why you would need more than 1 switch would depend on layout of your machines.. But from what I recall your switches are right next to each other.. So you only need 1.. And I would not suggest you connect anything to your router either -- unless location of PCs mandates it.. So should prob look more like this.

post-14624-1257190957_thumb.jpg

Here I added some printers/plotters -- so now it should look pretty freaking close to your network ;)

Well there you go -- you can pull your dlink out of the picture now ;) Your router is connected to the linksys one right?

I thought from one of your screen posts of ipconfig a wireless device?

Yup here

From your server you post shows a "Wireless-G PCI Adapter" And then you have it bridged???

Ethernet adapter Network Bridge:

Connection-specific DNS Suffix . :

Description . . . . . . . . . . . : MAC Bridge Miniport

Your server should not be doing any bridging between wireless and wired or any bridging for that matter!!! It should have 1 wired connected into your switch -- just like all your other machines.

Visio -- its a bit pricey.. But it does a nice job of network layouts ;) There are some free alternatives..

http://www.weresc.com/cade.php is one off the top of my head, there are a few others, if your looking to draw out your network. If you want could dig up some more for you.

But since I have access to visio through work, I just use that.

edit: yes danny you should connect the router to the linksys, since everything else is connected to the linksys and then remove the dlink all together.

edit2: BTW if you wanting to see some really nice layouts, just out http://www.ratemynetworkdiagram.com

    • Friday Windows 11 preview builds are here. Insiders in the Experimental (formerly Dev) and Beta Channel can download builds 26300.8697 and 26220.8690. My Windows11 device on the Preview Channel just got 26220.8728. My guess is this build is a nightly update from 26220.8690.
    • Traffic has a surprisingly unexpected impact on your surroundings by Sayan Sen Image by Radik 2707 via Pexels A collaborative study by researchers from several Israeli institutions found that everyday pollution from traffic and industrial activity measurably changed the atmospheric electric field over the Tel Aviv metropolitan area, providing new evidence of how human activity can influence the lower atmosphere. The research was led by Dr. Roy Yaniv of the Hebrew University of Jerusalem and the Gertner Institute at Sheba Medical Center, Dr. Assaf Hochman of the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University, and Prof. Yoav Yair of Reichman University. The study also involved Itay Froomer, a student from Hadera High School and the Israeli Museum of Medicine and Science (Technoda), who carried out the work as part of the Ministry of Education's 5-unit physics research track. The researchers focused on the atmospheric electric field under fair-weather conditions. Even in the absence of storms, a weak electric field naturally exists between Earth's surface and the atmosphere. One of the main ways scientists measure this field is through the Potential Gradient (PG), which is the inverse of the vertical component of the electric field. PG is a key part of the global electric circuit, a planet-wide system of electrical currents maintained by thunderstorms and electrified clouds around the world. Scientists have long known that the atmospheric electric field can be influenced by factors ranging from large-scale atmospheric processes to local weather conditions such as dust, fog and clouds. Human-made pollution is also known to play a role, but understanding exactly how urban emissions affect the electric field close to the ground has remained an area of ongoing research. To investigate this relationship, the team analyzed measurements from a newly installed electric field mill, an instrument used to continuously monitor the strength of the atmospheric electric field. The instrument was installed at the Center for Technological Education (Roter House) in Holon and became operational in August 2024. It was funded by Israel's Ministry of Education and the Holon municipality. The electric field mill forms part of a broader monitoring network that includes nearby meteorological stations and air-quality monitoring sites. This allowed researchers to compare electric field measurements with detailed weather data and pollution records to better understand what was driving changes in the Potential Gradient. The study focused on two major urban pollutants: fine particulate matter (PM2.5) and nitrogen oxides (NOx), both commonly produced by vehicle traffic and industrial activity. PM2.5 refers to microscopic airborne particles small enough to remain suspended in the atmosphere for extended periods, while NOx is a group of gases released during fuel combustion. Researchers examined daily, weekly and seasonal patterns in the atmospheric electric field and compared them with changes in pollutant concentrations. Their analysis revealed a clear relationship between NOx levels and changes in the Potential Gradient, particularly during morning and evening rush hours when traffic emissions were at their highest. “What we observe is a direct physical link between emission peaks and electrical variability,” explained Dr. Roy Yaniv. “NOx reduces atmospheric conductivity very quickly, so the electric field responds almost instantaneously during traffic rush hours.” Atmospheric conductivity describes how easily electrical charges move through the air. According to the researchers, nitrogen oxides rapidly alter this conductivity, causing a near-immediate response in the electric field. PM2.5, however, was associated with a delayed response. The researchers attributed this difference to the particles' longer atmospheric residence time, meaning they remain in the atmosphere for longer periods, as well as their different microphysical interactions with surrounding air and atmospheric components. The study also identified a pronounced "weekend effect." In Israel, traffic volumes and some industrial activity decline significantly on Fridays and Saturdays. During these periods, concentrations of both NOx and PM2.5 dropped, and corresponding changes were observed in the atmospheric electric field. “The weekend signal demonstrates just how sensitive the electric field is to changes in human activity,” the researchers noted. “When emissions decline, the electrical environment adjusts at once, providing a high-resolution indicator of urban atmospheric conditions.” The findings showed that pollution levels can influence not only the chemical composition of the atmosphere but also its electrical properties. Researchers said the results strengthened the case for using atmospheric electricity as an additional tool for environmental monitoring, particularly in densely populated urban areas where anthropogenic, or human-caused, influences are most pronounced. The study also pointed to potential public health applications. By combining air-quality measurements with observations of atmospheric electricity, researchers said they could gain a more complete picture of how urban atmospheric conditions change over time. “Integrating air-quality data with electric-field measurements gives us a clearer picture of how the lower atmosphere evolves moment by moment,” the researchers added. “It’s a framework that can support both scientific insight and practical environmental decision-making.” Beyond the scientific findings, the project highlighted a collaboration between universities, public institutions and secondary education. Researchers said the work demonstrated how students could take part in real-world environmental research while contributing to studies of air quality, atmospheric processes and their potential effects on society.
