Multiple times per day, I have an issue where I seem to lose the
connection to my server, which is the primary domain controller, file
server, SQL server, etc to my company. I can still make domain
requests, SQL queries, and other connections to the server, including
RDP, ping, etc.

For reference, a screenshot of what I'm seeing is here:

Server is Windows Server 2003 R2, and the workstation is XP SP3.

Any ideas?
