A friend of mine has set up Active Directory on a local school's server, which is running Windows Server 2003. The primary purpose of this is to allow a group policy to be applied to the laptops. He may also be providing server-side storage for the accounts, but I'm not 100% sure if that is set up.
The server is connected to a network switch, which in turn is connected to a wireless access point. The server runs a proxy server which, when authenticated by Active Directory, is used by clients clients to access the internet. In their IT facilities there are 20 laptops which connect to the wireless access point, each of which is configured to access Active Directory on the server.
The problem is that when the laptops log into the server, it works for a short time then the laptops can no longer access Active Directory server. At first he thought the wireless AP was being overloaded, so he changed it but the problem remained. When this issue arises, the server machine freezes on "Loading your settings..." when you attempt to log in to the server physically. To regain control, the server must be hard rebooted (reset button on front of case).
The network connection itself seems fine as two network switches and two wireless APs have been used with no resolution to the problem. The event log shows nothing suspicious other than a few unusual network disconnections and automatic reconnects.
This is a reasonably urgent issue and a speedy response would be highly appreciated. Thank you in advance.
