User Login to a Win 2003 DC

I'm not sure where to begin, but I have a problem that I just can't seem to solve, and it has to do with 2 and sometimes 3 users having problems logging into our server. We are using a Windows 2003 Server as a DC, and we have another Windows 2003 Server set to a file server only. I have a total of 25 users, both desk top and lap top (very small network).  All 3 of these users are using Windows XP as the OS, and All completely shutdown their computers at end of day!

I have checked these items:
1. User name is correct
2. Domain is correct
3. User is using the correct password

Almost, but not every morning, after the computer is started, this user types their correct password and they get a message that says: “either the domain controller is not available, or user name or password is incorrect”. Sometimes they can retype this 3 to 5 times, then it connects, and other times they have to select shutdown and restart their computer. After restarting, they type their password, and it works!

I do not understand why this is taking place, as I have seen this happen, and even typed their password in myself, and the same error message appears.

Like I said, this doesn’t take place everyday, but it has happened many days in a row, then stops for a few days to even a week, and then starts up again.

I have no clue where to even begin to locate an answer as to why this is taking place.  Your assistance would be greatly appreciated.

Thank You

Check their DNS is pointing to the Domain controller (assuming your DNS server is on the DC)
You may want to try removing, adn re-joining the machines to the domain

Possible that I just found the problem. I had an extra DNS listed within my router that was sending down to the clients computer. I'll know more after I complete a few static test.
