I have NLB cluster running on on 2 Windows Servers 2008 R2 Standard. Two webservers running Sitecore. When I first set up the cluster, everything was fine. Now, when I run NLB console, I can only see one of the servers within it. For the second server it tells me there is en error connecting to it:
"error code 0x80070721. Error connecting to server XXXX"
If I connect to this server thru Remote Desktop, I see same thing for another server. Both show status - converged. So, I assume they both connected to the NLB cluster, but not being able to connect to the console.
