I'm going to try my best to describe the problem since I'm not the SysAdmin!
At my office, we have multiple PCs who connect to a Microsoft Server 2003 - Entreprise Edition.
We didn't do any modification to the server, but for some reasons PCs have problems holding a connection with it. Even tho the server is managing the loggings, they stay connected. When they lose connection, i feel like it's just for about a second, and then it goes back on. For exemple : they connect to the server, see their documents, browse, and when say open something, it hangs. Sometimes it works, sometimes it doesn't
I don't know what kind of information you guys needs, so just let me know if I can help :)
