yes, I have in fact, I am trying to resolve this. go to run >> dcomcnfg >> Look in your event viewer .

see dcom error 10010. I get this error running procedure from server1 calling procedure on server2. AFter almost an hour. It will give me this error. Then client ssms will dissappear. I believe it is a client issue on sql server 2008.

The server {7E477741-01A6-4C06-9DAC-55F6174C08A3} did not register with DCOM within the required timeout.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

this is a client side issue.
