I have a box running Server 2012 r2.
Box operates fine with one issue, sporadically (can be days/weeks between occurrences) it partially loses network connectivity.
By partial, here are the symptoms...
What you cannot do -
You cannot connect to server via Remote Desktop
No internet connectivity at the server
No network connectivity from server out through windows explorer
What you can do -
Can connect to the server through windows explorer and mapped drives
Issue is resolved with a reboot of server.
Tried looking in event logs, but not seeing any correlating errors. And because it doesn't affect windows explorers ability to connect to the server, the only time it is noticed is if someone tries to connect through remote desktop. The only potential clue are about an hours worth of NSSM informational entries in the application log within a days time of noticing the connectivity issue. There are many different messages but seem to revolve around ISFhost services. Not sure if related.
Any thoughts on how to better troubleshoot?
