Hacker destroyed remote desktop access

I had a server compromised, I'll traced their damage and resecured everything (i hope). However, they must have damaged the files that run remote desktop because I can't connect. The server immediately kicks a session off, no login screen or anything. I am connected with VNC and can see that the server is listening on port 3389 and remote desktop is enabled. I do not have Terminal Services installed, I believe that's a different system.

So how could I go about "reinstalling" remote desktop? Or any other ideas?

Thanks!

Hi elmoredaniel,

If the server has been compromised - and this has been confirmed - I wouldn't think twice about simply wiping it and restoring data from backup.

RDP is just one thing that is going wrong here - who knows what else has been damaged (or changed).

Also, if you have a domain, start checking all the domain accounts

Hope that helps,

I'll consider that, but for now I need to get back in there without VNC (it's slow and buggy). What do you suggest about get RD back up?

If you are happy to run a computer that is probably still compromised, and just want to repair RDP, I would try the following, in order;

reinstall your video drivers
sfc /scannow
repair install of windows

This machine must be wiped though (I know you know, I am making sure you REALLY know :)

Run Winnt32 from the i386 directory on the local drive.  Follow the prompts to repair.  If this fails to solve it (as I suspect it might) then run Winnt32 and choose upgrade.  This will do an inplace upgrade and should only affect patch levels.

Make sure you know the CD key that machine is using.

If you don't know it, you can find it using Keyfinder.  http://www.magicaljellybean.com/keyfinder.shtml

Sorry for the delay. I started Winnt32 but there was no option to repair. I could only choose "Upgrade" or "New Install"

Did you go for Upgrade, as suggested by Netman?

Netman, Isn't the repair option only in the dos section?

Yes, my mistake.  Repair is only there is you launch the DOS setup.

Glad you're up and running.
