Whew...here we go. A local free clinic has had the same guy who setup all of their computers, servers, printers, etc for the last 5 years. Recently he was arrested for stealing from one of his other clients and for obvious reasons they decided that they wanted to change all addresses, passwords....basically remove any chance of him still being able to access it so they hired me to do that. I went in and changed all of the local and domain users passwords and disabled his username, changed external port numbers for port forwarding, etc and everything was working for them fine.
Over the weekend we had a bad power outage that lasted like 30 hours and today they cannot connect to the domain controller (which is also used as the server for a program they use). I went in and plugged in a monitor, keyboard, and mouse into the server (it is normally "headless") and saw that it was getting stuck trying to do a Startup Repair but it was failing. I told it to start Windows normally and it booted fine after that, but when I try to login with a domain user account it says "No logon servers available." Normally I would just remove the computer from the domain and add it back but I have never seen a domain controller say that before. Any suggestions?
Have you logged into the server locally and made sure the "Net Logon", "DNS server service", and "DNS client service" are running?
That's assuming you're using a Windows Server OS.
What server OS is it running? That would greatly help us - help you.
Sorry I didn't post that. It is currently running Server 2012, I did not have a chance to check those services because I just stopped by there on my lunch break from my real job. Originally they just called and said that it was turned off and said they could not find the power button so I wasn't planning on having to do much. I am going back after work to try some more but figured I should go ahead and post so that I could have some suggestions since I wasn't sure where to start. I hate taking over servers that were set up by someone else!
Thanks for the reply, I will try that first when I get there after work.
