Ran a health check on our Exchange 2010 org and came across this in the baseline tab: The value of the Windows Management Instrumentation (WMI) setting 'Win32_NetworkAdapterConfiguration.Index=7\WINSPrimaryServer' on cluster node MXMB02.CNYBUILDERSLLC.local differs from that on node mxmb01.CNYBUILDERSLLC.local (172.18.1.211 <> 172.18.1.210). Everything seems to be running well, no errors in event viewer, but I was curious if there's something wrong. I checked WINS settings on all three mailbox servers (MXMB01, MXMB02, MXMB03) and didn't see any discrepancy.
