I have a realy strange error on one of our servers.
When I open the event viewer and try to open one of the eventlogs (application, system...) the MMC freeze up and the OS totally loose control of that session with MMC. I'm able to start another MMC and perform whatever I want except looking at eventlogs.
When I try to log off the server it is not able to log me off, and if I try to log on locally or connect to the server on RDP it's not possible. To be able to logon I have to disconnect the power or hold the powerbutton pressed until the server is turned off.
And now to the situation which to me makes this really peculiar...
If I open the log files from another server (event viewer/connect to another computer) I'm able to open the logs without any problem. If I have opened the logs remotly BEFORE I open them locally I have no problem at all! I can open the event logs, log off/on open the eventlogs and everything looks great. I'm also able to log off and log on again and still able to open the eventlogs.
