So I am runnign a Windows 2000 and 2003 Server network. Primary DC is 2003, and secondary DNS is 2000. We have been having someweird network problems. In active directory users and computers, every single user's account suddenly locked out- then 10 min's later after I unlocked them all, they locked again. Then I noticed that user's network mapped drives were disconnecting. The client IP addresses are all set to DHCP FYI. Even people in Outlook were prompted o enter a password, domain, and username while they were logged in and using Outlook. Did we get hacked or is something crapped out? All of the services running on the Servers looked fine, and event viewers showed nothing out of the ordinary. One thing I noticed was the secondary WINS server could not find the primary (which is one of our DC's) I started it back up and all seemed fine- but then the problems continued. Utter chaos. What could be some possibilities here?? Please help me out guys!!
