I have an EMS server with two TMG 2010 nodes joined to an array. These nodes are Windows 2008 R2 Datacenter servers and NLB (multicast) within the array.
I had these servers in an array with no problems for about 24 hours, then the next day the EMS console displayed an error "unable to retrieve data from both these TMG nodes".
THese nodes are correctly listed in the appropriate "Computer sets">>" Array members", etc. DNS resolution is OK between these hosts.
Any idea what I can look at to resolve this problem?
you should check your logfiles on TMG, the eventlogs from Windows Server to see what has been changed shortly before the error occured
Do you have any update about this issue?
