Error: Unable to initiate DCOM communication
A DCOM error occurred when the local machine tried to communicate with the remote machine. This is caused by a firewall on the remote server or broken Windows authentication on the remote machine.
To correct this error
If the remote machine has Windows Firewall enabled, see How to: Set Up Remote Debugging for instructions about how to configure the firewall for local debugging.
To restore Windows authentication, try rebooting both machines. Examine event logs on local and remote machines for Kerberos errors and contact domain administrators for known problems.
