In my office, we have countless Windows workstations communicating with a server. We don't have a domain. All worstations and the server are in the same workgroup. All network connections are wired. We log into the server with a username and password different to that of the workstation.
One Windows XP workstation, just one in the office, takes up to 60 seconds to open a document on the server. If I save the document to the desktop and open it from there, it comes up instantly. If I use a similar workstation in the same room, the document opens from the server instantly.
Net Use \\Server\Share makes no difference. IP addresses and DNS are DHCP assigned and no conflicts are detected.
I am at a complete loss as to what the issue could be. It just occured to me that AVG is running and I'll investigate that. Do you have any other ideas?
