The interface is unknown / The System Event Notification Service service failed the logon.

customer informed server is in accessible via RDP and not responding to the ICMP,
 
how ever VM is accessible from the console , and it's a 2008R2 server gives below error when login to the console,

The System Event Notification Service service failed the logon.
The interface is unknown

 

first thing we noticed VM tools showing as Running(Not Installed) - it's seems this is common when VM tools corrupted or Open VM tools installed on the server

 

so we go ahead and re install correct VM tools and it fixed the issue .
