Everything worked last night.
Everything is working for every computer except one now. That one computer (out of 20) is saying that credentials are incorrect when trying to browse shared folders on one of our servers (win 2003 r2) the other server (2008) is able to be browsed fine. I am able to connect using RDP to the server from the affected laptop using the credentials that are supposedly incorrect when trying to browse (or map a network drive). I have searched the internet for about an hour and not found any fix. Thanks in advance.
I'm assuming this is a security issue rather than a networking issue but no settings have changed.
