Domain Controller is Down

I get this error when I attempt to log into a network account:
"Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your system administrator for assistance."

I can only log in using the local admin account. Its not letting me sign on using a network logon. I know that the accounts are working, so I assume there is an issue with the domain controller.

Any ideas?

Time for the IT staff to get to it.

They'll check the ethernet out or re-image the machine if they think it needs it. Then again I'm running into companies that have ejected the IT staff and they end up begging for help.

domain

In reply to: Domain Controller is Down

when you login with your local admin account are you able to ping the DC? Also, check the IP settings to make sure they are correct. Are you using DHCP or are you static? If you are able to ping the DC adn IP settings are correct, is the computer name in Active directory? Also if the computer name is in active directory, is it disabled? If you check all these things and you are still having issues, drop the computer from the domain, rename it and create the new name in Active Directory and then add the computer back to the Domain. Somewhere along the line of following these steps, you should get the computer back inline. If other computers are able to connect to the domain then it is definitly an issue with this computer name or a setting on this computer.

For the archives: DNS as a possible cause

In reply to: Domain Controller is Down

Another possibility is that this is a DNS issue: here's the scenario.

Let's suppose you have configured both a primary and secondary DNS server for your computer's network adapter. The primary DNS server is the DC, and the secondary is some other machine, possibly a router or similar appliance on the LAN. As such, the secondary DNS server probably has no idea of the existence or location of the DC, but it may actually respond more quickly to a DNS query ... and, as a result, you will get the above-mentioned error.

If this is the case, remove the secondary DNS entry from the network adapter's TCP/IP properties.
