The users are on a domain and the files are not setup as active directories.
? That doesn't make any sense to me.
Fixed to clarify.
Active Directory is an authentication framework not files and shares. I am still confused. Does lock up mean freeze / bsod / error messages.. ?
Ok, I have a misunderstanding of what Active Directory is. There are no errors server side, but client side the users can no longer access the server.
Is anything logged in the event logs on the clients or servers?
Clients are XP? Is 2003 fully patched? Is the server and the clients (and users) all members of the same domain?
Don't hold back on the info.
