scanning for bad ram

[Paul A]

Nick,

that makes sense and I will be doing the test offline soon. I did setup OSMA
on the server and can https to it. The log/alert files don't show anything
out of the ordinary with the ram. 

I do have one more out of topic question, I setup IT assistant on my desktop
and I can see certain servers that have the latest versions of OSMA but not
all of them even though I can https to them. These are servers on the same
vlan using the same ACL's/Firewall but I can see some but not others through
IT assistant. For some reason I can only see 3 servers out of 6 that I have
the OSMA software installed. I installed OSMA from the dell REPO.

Any thoughts ? 

Thanks,

paul
