SBS2008 DistributedCom error
Hi
On my SBS2008 server I have hundreds of System Errors in the event viewer, all saying the same thing.
"DCOM was unable to communicate with the computer PC.domain.local using any of the configured protocols."
Windows Firewall is OFF.
I'm not even sure if this PC is even on the domain anymore, is there a way I can check when it was last connected to the network?

It doesnt respond by name or IP, but it could well be becuase it is off.
It's still part of the domain but I have a feeling the PC was one that we chucked ages ago due to a hardware error.
Anyway to check last domain contact?

Hmmm... you must have a LOT more stations in your SBS domain than I am used to. I know the names of each system and where they are becuase the nameing conventions help me figure it out and becuase the documentation says that WKS01 is currently used by Sally.
But, afaik, logons are by user, not by station.

not really, they have about 10 stations total, but naming conventions are all over the place, making it very hard to pinpoint.
maybe what I can do is remove all traces of this workstation from DNS and see if it reappears after a week or two.
What is that error about anyway?

Unable to communicate.... = can't find it.

I reckon its an old PC.
Will removing it from SBSComputers in ADUC fix it?

As in all things SBS, use the Wizards.. in this case, from the Server Manager console.

I was not aware there was a Wizard for removing a computer object?
In 2008/2011 it is under Network, Computers Tab, highlight a system, on the right - Remove.
ASKER
Ok, removed.
I saved and cleared the log, will check back in 1 or 2 days to see if it still comes up.

Well, I cannot see any errors for that machine anymore.
However, a lot of other machines are now showing instead - mostly laptops that spend the majority of time offsite.
Some of these are not even domain-joined.
Is it safe just to ignore these errors, and/or can I get rid of them somehow? I cant delete their computer objects becuase they are live machines, mostly which connect in via VPN.

What happens if you ping it by name, then by IP address?
