I have a strange problem and hope someone can help me. One of our Server 2012 hangs completely up. Nothing from the services (file, print, ...) is reachable an monitoring over snmp is not possible anymore (network monitor alerts). But the ping to the server is working fine. When I try to connect with RDP to the server I get the user authentication form -> enter my user and password -> the loading bar appears but after some time it throws an error. Anything what helps is to hard switch off the server and restart it again. That occurs the second time - last time Sunday 01/25/2015
I found no errors in the event log.
Thanks in advance for any help. Please tell me if you need any information.
