Windows Server 2008 R2 password and account issues

Hi all, i have potentially a serious problem. i have recently installed a new server and setup remote desktop services for all the users. Only myself and 2 other usernames were administrator privileges, i got a call from on the staff members saying the password is not accepted and to ask if i changed it. I have since found all administrator account passwords are not working, some usernames are not even listed anymore in computer management and there are 2 more accounts setup as administrator access. These are called MicrosoftTM and Systems.

Can anybody please help me, is there a way to retreive the passwords, or perhaps restart the server with standard user access incase its just needs a reboot, or is it more serious and someone has gotten into the system and stuffed around with the settings.

I had a look through event viewer but could not see any logs that mention password changed or anything like that.

On the face of it, someone or something has compromised your systems.

It isn't uncommon for people to name an account something that would, at a casual glance, pass for a system or Microsoft account.

System / Sysetms - very close. There is no inbuilt account call Systems or MicrosoftTM.

Is the problem Domain-Wide?

If so, you may be better off isolating the RDS box (was this internet facing? Do you know for sure it was the attack platform?).

I would look to get hold of a boot-CD that can change the password on that machine and then trawl the logs to see if you can determine who, why and when it was changed.

If it's domain wide you will need to restore AD I'm afraid - I would do it in parallel with the above.

Do you have strong password policies in place? Many attack vectors for RDS on internet facing servers look for weak passwords on port 3389.

Were any new group policies applied after your Server was put into production?
Even a simple task like moving a computer from existing OU or Computers container to another OU could result in new Group Policies being applied.

If you have local accounts then the restrited accounts policy could remove the other accounts.

Run:
gpresult /h gpresult.html
or
rsop.msc
to see the Group policy settings that are being applied to that computer.

Thank you for the replies, indeed it was some spyware junk on the server. I managed to reset the admin password and get back into the server. however it had continual virus related issues so in the end I had to reformat and start again. Fingers crossed it doesn't come back.
