we have Networker server Redhat NW 7.6.1.3 and HyperV server W2k8R2 with NW 7.6.1.2 and NMM 2.3.

Backup aborts with error: NMM.. Exception caught: Could not connect to IRCCD service on port 6728 of host IT2m1125.it2mtech.de

No debug is written, firewall ports are configured and open. All NW and RM services are running.

Any idea about the reason of this error.

regards

Bernd
