Windows Server 2008 R2 64bit Screen Frozen and Remote Desktop Freezes but Server Continues Working

Solution 1:

It might be the cause of memory exhaustion . I have the same problem , not able to login through remote or locally. Black screen comes out after login. As per the monitoring tool my server is consuming 99 percent of the memory.

Solution 2:

I have a redundant set of AD servers that periodically do the same. Those are (luckily) the only Windows servers we run. What happens is that the user.ini file gets corrupted, particularly on a lengthy Windows update session. The only thing that helps is (since of course it does not find its recovery partition, and a command line does not help) to take the OS disk out, put it on a USB-to-SATA adapter, connect it to any willing PC, and manually go through the directories in the \user folder and delete everything with the extension .ini. Pop the disk back into the server, boot it up, and restore all of the users' desktop and such, for all users (in our case there is only one user, and that is admin) since these servers really only need to run AD. Terrible software design.
