RPC server unavailable


Scott Elgram

I have recently been experiencing a problem on many of the computers on
my network. All these affected systems are having trouble logging off.
From what I have been able to find out I believe that this problem is some
how related to similar errors like this:
The COM+ Event System failed to fire the Logoff method on subscription
{AAD1D51F-1279-4831-8684-D99F99B3CC62}. The subscriber returned HRESULT
After some research into these problems I found that 800706BA refers to
0x800706BA which means "The RPC server is unavailable". This is where I'm
stuck......if I am understanding this right it's a problem with my Win2k
Server and or the communication between the server and the affected
machines. I also found that this is a side effect from the MSBlaster virus
because it utilizes DCom and the RPC server for it self. So I ran scans but
found nothing.

Any suggestions on how I may resolve this please?

Hi Scott,

I see you posted the same issue on Fri Mar 18, 2005 8:24 am.

You should do a search in the Registry Editor (REGEDIT) and try to figure out what this GUID belongs to.

Because this GUID is not natively created by the OS.
Once found, export it out then deleted it to see if you continue to experience the same event.

Hope this helps,

Yeah, this issue has been driving me nuts for some time now. Interestingly
though the GUID changes between machine and between occurrences in an even
log. I tried searching the GUIDs on the registry buy come up empty handed
every time. The only other connection here that I have been able to make is
that all the affected machines are running MSN Messenger so I am leaning
towards that being the problem instead of my DC or network.
