Windows 2008 server looping with microsoft updated


We use windows 2008 server as our DC and the space on C drive had fallen down to 0 bytes.
and I restarted through RDP connection ,which I had and now the server has booted up I can't RDP. I went to the server locally and connected a monitor and  I  noticed that its doing windows updates.
It says installing update 1 please wait. This is continuing and now its more that a couple of hours and have not completed. Any suggestions to sort this will be much appreciated.

With 0 bytes free, your server will not be able to do anything, including finishing the updates it is working on.  You must free up space for the system to work.

Clear the obvious, temporary files, log files etc.  Look for things like Antivirus signatures that are no longer used, large user files.  

Use a tool like space monger ( which does not require installation ) to find space hogging files and get rid of them.

After you've cleaned up space find ways to better utilize your space.  You should keep at least 10% of your volume free at all times, to give the OS room to work.

Your first problem is free space on the C drive. You might try moving the paging file to another drive to free up space on C. Clear out all misc log files, reduce the size of the Windows logs if they are large, clear out all junk.

We use FileTree to evaluate what's using disk space. it's a great app.

At the moment I can only access the C drive through the UNC path.The server screen is on the windows update screen. if I give a hard boot to the server will I be able to see the Cntrl+Alt+Screen  and then clear up the space. Will clearing the Temp folder contents from UNC path make a difference
