Cannot get any WMI sensor to RPC to an Exchange 2013 server. I've checked everything down through nmap, wireshark and procmon and verified there is complete and consistent network connectivity to the server over port 135.

Interestingly there are only two RPC related processes I see in procmon on the Exchange 2013 server:

1.) Microsoft.Exchange.RpcClientAccess.Service.exe -> QueryOpen ->C:\Program Files\Microsoft\Exchange Server\V14\Bin\Microsoft.Exchange.RpcClientAccess.Service.exe.config SUCCESS

2.) store.exe -> RegQueryValue ->HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\RPC Retry Count NAMENOTFOUND

Since both of these are Exchange related RPC, I've tried mail server specific WMI Sensors and still got PE015 RPC unavailable. This is a multi-domain environment and there are plenty of other servers with WMI sensors in this domain working OK, this is specific to my Exchange server.

Not sure where else to look, I've been through ALL the RPC related error documentation and tried it all. I'm stuck.

Hello,

If the Exchange server belongs to a different domain than the probe, then please enter the according domain administrator credentials of the Exchange server's domain into the device settings. Additionally, please have a look at the following site which describes the monitoring of servers outside of the PRTG server's domain: https://helpdesk.paessler.com/en/support/solutions/articles/203.

I've added the monitoring account both locally and in either domain of both servers with the same username password.. verified remote management, changed the PRTG probe service logon account.. the firewalls are completely turned off and I see the RPC connection in Resource Monitor.. but somehow I'm still getting error 800706BA.

Again, this is only happening to my Exchange 2013 DAG cluster servers, where every other server in the other domain has WMI sensors running normally with no problems.

The only common denominator here really seems like Exchange 2013. Not sure what else to try and this is highly frustrating as it's a critical sensor for us and I've spent way too much time on it already.. looking at Nagios.
