I have SBS 2003. All client computers are XP Pro SP 2. Everyday almost exactly 9 hours after logging on to the client computers, the connection to network resources (such as shared folders) seems to become unbearably slow until the client computer is restarted. Then it continues to become slow about every hour after. Granted I shouldn't be working 9 - 10 hour days, but i do. Anyway, it is not a utility or something that runs at the same time everyday because it completely depends on what time the client logs on. Also, logging off for lunch or whatever through the course of the day seems to make no difference. I am not even sure if this is coming from the server or the clients or the router for the network, but I have tweaked every setting I can find and had no luck. Any thoughts. Thanks

You should gather performance info when the server and client is running okay (for comparison sakes) and when it goes to heck, specifically looking for processes. Task Manager will do this fine, just be ready. Make sure when you click the Processes tab you click view, select columns, and then check CPU Usage, Memory Usage, I/O Read Bytes, Paged Pool, Non-paged Pool, Handle Count, Thread Count, I/O Writes. I'd start on the server. Make the window viewable, do a screen capture, and then leave it up and ready for when it spikes. Screen capture it again, and see what is spiking for processes. I'd also look at network utilization as well. "Milk was a bad choice!"

I have the SAME exact problem. I also have a 2K3 SBS server running windows XP. On the XP workstation that are on the domain, I also lose network connection after 9+ hours. I have a XP workstation that is NOT On the domain and I have the 2K3 SBS server drive mapped, and that is not losing connection, only the PC's on the domain are losing connection. any help will be greatly appreciated.

"I also have a 2K3 SBS server running windows XP." That's a new one. "Milk was a bad choice!"
