Exchange: No DNS servers could be retrieved from network adapter that doesn't exist.
On Exchange 2010 in Event Viewer I'm getting 205 errors: "No DNS servers could be retrieved from network adapter b6ec8a19-09c6-4450-b4f5-77
Running Get-NetworkConnectionInfo gives two NICS (which are the internal and external ones)

neither of which seem to be the one giving the error.
Checking HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > WindowsNT > CurrentVersion > NetworkCards gives two additional NICs, both Realteks, but with different GUIDs.
A search of the registry for the GUID finds nothing.
How can I stop this error I I can't find the device it is referring to? System seems to be working OK. We are running as VM on XenServer host. Guest is Win 2008R2 SP1, 24GB RAM, Exchange 2010

Is this a physical or virtual server?
Follow this https://technet.microsoft.com/en-us/library/ff184583.aspx and enable displaying non-present devices. Search for network cards no longer present

On Exchange, the External DNS Lookups was not configured (Use Network card was selected, but field was blank). I've now set it and the events have stopped occurring. Looks like the blank un-configured setting was triggering some rogue event. Would have been much more useful if address was given as 0000000-0000-0000-0000-000
