RPC, DCOM, WMI running..
I don't have auditing turned on.
Thanks for the pointer to the tool.
error: 800706BA: The RPC server is unavailable
Googling that hinted toward DNS issues...
It was DNS issue/conflict.

I had previously had all computers in the workgroup using my ISP's DNS. (RPE worked then)
Then I changed this computer (the one with RPE) to use OpenDNS. (it blocks alot of bad sites preventing some malware attacks and some advertisement junk)
I dont use RPE every day so I never thought of/remembered anything I had changed on network.
I changed it back & RPE works fine as does WMItest.
PsSsupend/pskill works awsome so far. Have not had chance yet to try on malware processes but only tested on other unneeded processes.
Sweet!

Thought I would mention what was wrong in case someone else runs into the same issue. Check DNS settings on the RPE computer & the one you can't reach...
Now to have it list dlls and handles under processes in new window or lower window actually listing dlls/handles.. (something like sysinternals process explorer does)
