I have a single server that is in a NLB configuration. There used to be two servers but we removed one and I kept the NLB so that I didn't have to change the IP address settings for all of the RDP clients that still connect to the one remaining server.
This was working fine for years until yesterday. None of my users are able to RDP to the termianl server. I tried to RDP to it via the NLB IP address and the IP address assigned to the server. I am able to ping just fine.
I check the NLB manager and everything appears fine. I right clicked the server in the NLB manager and selected control host and then stop. Then I tried to start it again and received the below error.
"Start" operation result : FAILURE (Cause : Critical Error, Check NLB status on machine)
I had this same issue yesterday so I removed the host from the cluster and then added it again and everything was fine. This morning, I have the same issue again and I am unsure why.
What could cause this and how do I resolve it?
