I am having an issue with a server in a secure domain, the event log is full of DCOM errors. The log is full of them and new logs appear at a rate of 3 per second which is difficult to work with when troubleshooting issues.
Now I am aware that these errors could be caused by any number of reasons but whats strange is that the addresses DCOM is trying to contact are on an external WLAN and none of the addresses can be pinged..
I have tried installing Wireshark to capture the traffic to find out what is generating these errors but nothing obvious shows up.. just wondering if anyone has any suggestions on how to troubleshoot this?
RPC port is not blocked as far as I can see
Addresses are on external WLAN do not have access to the server anyway so not sure what happens there
