Please assist...we have had the network connected and working without a glitch for the past 3 years...then all of a sudden couple of days ago the whole network stopped working.
Set up is like this: We have Server running Ms Windows server 2003 and other small applications like ms access database, active directory etc. We also use this server as a file server. The server is connected to total of 4 D-Link 1024 switches, the client computers then connects to these switches...(flat network). All the client computers access the server this way. These four d-link switches are connected up using a patch cable that run from one switch to another...on some of the switch ports we have connected a total of 8 Wireless Access Points (mix of D-Links and Zyxel). That is how our network is set up...
The problem: It started as a slowness on the network, then followed by some of the access points not working. We troubleshoot and realise if we disconnect some of the access points the switches start working, so we isolated 3 access points. This solved the problem only temporarily, after 2 hours we were back to square one: the access points that we thought are causing the problem are not the problem anymore!! It is as if the problem has now moved to something else...if we disconnect a number of users everything works well for a short while before the problem reappear with other symptoms...it is like the source of the problems keep changing.
Please assist what are the possible issues that can cause this from happening.
