Domain Server 1 800xa Alarm "Computer is not reachable"
I have a (DOM01) Domain Server 1 800xa Alarm "Computer is not reachable" but the server is running, I can remotely log into it, and it is shown online via RnrpMon. I have resterted the server a couple of times but the alarm has been comming back within a couple of hours.
I can see nothing in the event logs on the server to explain this. A couple of client errors (trust relationship), But all are working.
Any susgestions out there?
Looks like you have PNSM Basic Computer monitoring used and Domain Controller node is configured for monitoring
If so, there can be multiple reasons for this error, few are as below:
- Check if Network discovery and file and printer sharing option are on in Network sharing and access on Domain Controller node
- Check if firewall exceptions are added properly for PNSM
- If trust relationship related errors are there for PNSM server node also then rejoin the PNSM node to the domain
Hope this will help you
