Windows Small Business Server 2011 problems with DCOM error 10009
Had a issue a while ago with Event 10009, DistributedCOM flooding my System Event Viewer.
At fist i have tryed communicating DCOM with great tool named "DTCPing" it can be found on Microsoft support site: https://support.microsoft.com/en-us/kb/259011
I have run the tool on my SBS 2011 server and Client (Windows 7 Pro x64).
Now from the Client -> Server connection the tool worked great and it loged that "RPC test is successful" but from Server -> Client related connection it gave me error:
Invoking RPC method on CLIENTNAME
Problem:fail to invoke remote RPC method
Error(0x5) at dtcping.cpp @303
-->RPC pinging exception
-->5(Access is denied.)
I have read alot of site's and nothing really worked. Checked the Server's firewall in "Inbound rules" and "Outbound rules" for "Distributed Transaction Coordinator" and enabled them but the (Access is denied" was still there.
So i have found this helper:
Witch resolved the problem and DCOM stareted to work on client and server side.
So this is what helped my problem:
