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 is running Windows XP Service Pack 2 and the Windows Firewall is enabled, see How to: Set Up Remote Debugging for instructions on how to configure the firewall for local debugging.

  • To restore Windows authentication, try rebooting both machines. Check event logs on local and remote machines for Kerberos errors and check with domain administrators for known problems.
