Lost trust relationship between workstation and primary domain controller!!
I have had workstations lose their trust relationship with my DC before, and logging on as local administrator, taking the machine back out of the domain, restarting and putting the machine back into the domain usually fixes the problem. I have a machine that won't logon to the local admin account with the same error?? Why would the machine still give a DC logon error when trying to logon to the local admin account?? If I unplug the machine from the network and try to get into the local administrator's account, I get " There are currently no logon servers available to service the logon request.." I really need help in trying to recover this machine without having to completely rebuild the workstation...

what operating system do you have and are you really trying to logon using local administrators credentials ? Please do let us know the exact error. Could you please try the same thing with the safe mode . http://www.virmansec.com/blogs/skhairuddin

Hello, if you have multiple DCs then I suspect that there is something wrong with one of your DCs (possibly a replication problem). Please use Microsoft Skydrive to upload the output of these commands on all your DCs: ipconfig /all >c:\ipconfig.txt [from each DC/DNS Server] dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt ["dc* is a place holder for the starting name of the DCs if they all begin the same (if more then one DC exists)] dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045) Once done, post a link here.

Thanks for the quick response... Fortunately, I figured out my problem. I had the user's computer name wrong when trying to logon as local administrator. Once I had the correct computer name, I was able to logon as local admin and remove the workstation from the domain, restart, and re-add to the domain without incident... Thanks again...

Good for you but please specify how many DCs you have and post the files I suggested. I suspect that you have replication problems and if yes this may explain why you lose trust relationships.

Actually, my problems were caused by two machines (both in HR) having the same computer name... I realized it after having problems with the second one, that it had the same computer name as the first one I had problems with. I changed the computer name on one of them and totally resolved my issue. So in conclusion... My problems were human error!
