I have windows server 2003 and when it rebooted after a power failure it will not let me log into the windows login using the admin username and passord now. It says "system could not log you on. Make sure your user name and domain are correct." and if I use a client login thru the same login window on the server, it says " The policy of this system does not permit you to logon interactively. My main problem is I have only the admin setup on server to log into the server. It does not recognize the admin login and gives the message first listed here. A different message (the second one here) appears when I use a client login on the server.

I think the trust between the client and the server is lost , maybe it will be solved when you reset the servers computer account on the domain controller , But in this case i have used a third party application to remove my local SAM database passwords :http://www.password-changer.com/The system does not permit you to logon interactively is described in this article :http://support.microsoft.com/kb/289289http://support.microsoft.com/kb/841188i hope it will help you.Network is my LOVE
