Cannot connect to DCOM port 135 : Firewalled?

[bubblie]

Good Morning we have approximately 185 machines about 12.49% of our machines that have an Important message Never Scanned OS. We are mostly a mobile environment and I am not sure if this is the result, however I find that number to be a little high. I am also finding servers on the list. When you open one of the machines there is no info. However when you click the errors you will find the same error on each of the machines
• Wmierror Cannot connect to DCOM port 135 : Firewalled? (machine name)
• The RPC server is unavailable 0x800706BA (Machine Name.Domain Name)

Thank you for your assistance.

Most likely it's the windows firewall blocking access to the computer.
You can test this yourself by trying to telnet to port 135 on the machine.
