PNSM need to be able to remotely execute stuff over DCOM. I assume the node EWS-2 exists and is available over network?
If EWS-2 is not reachable, these messages are natural. Remove all IT Assets and Basic Computer Monitoring objects for nodes that are not existing.
Otherwise, something may be wrong with the service account in EWS-2; eg is it made member of local admin (or domain admin)?
Try accessing EWS-2 remotely from the PNSM server node by eg reading the C$ admin share by executing:
(at PNSM server)
C:\> dir \\EWS-2\C$
Hi
Can you check on following firewall rules on PNSM Server (where ABBshadowOPC.exe is running) and Computer ZZZ.
DCOM Configuration: Configuring the Windows Firewall
o Open the Windows start menu
o Select "Settings / Control Panel"
o Select "Windows Firewall"
o Select the "Exceptions" tab
o Click "Add Program"
o Add the following programs:
o ABB Shadoe OPC.exe (Only on PNSM Server Node)
o Microsoft File and Printer sharing
o Select the "Exceptions" tab
o Click "Add Port"
o Set the following preferences:
o Name: "DCOM"
o Port number: "135"
o Select "TCP" radio button
o Click "OK"
Best Regards
