This one is VERY interesting.
I have a Windows 2008 server that functions fine UNTIL someone tries to upload a file to a remote server on the web. Here's the scenerio:
A Windows XP computer uploads a file to a website (claims file). This file is sitting on the W2K8 box and is accessed via a map drive on the Windows XP machine. The upload goes fine.
They then try to upload another file and that is when the network seems to "hang." In researching and narrowing it down, it is actually the Server service on the W2K8 box that hangs. There are no error messages in Event Viewer and the service doesn't "stop" it shows running. But when you try to restart the service, it hangs in trying to be stopped.
Solution: Reboot the server (Not a good solution, obviously)
This happens on every workstation in the office. It also happens when you try to upload the file to a different website.
Anyone got any ideas?
