Enabling DCOM in Windows Server 2008

  • Article

In order to make DCOM applications work in Windows Server 2008 you need to do two things. Installing the Application role is not needed (but it does add the COM+ network access as in 1) below).

  1. Allow "COM+ network access" in firewall rules (type firewall.cpl from a command prompt and on the left you'll see the setting). COM+ is somewhat of a misnomer since it is also for DCOM. COM+ Network Access is a preconfigured program in the exception list that you can just check off.
  2. Add your DCOM server to the list of program exceptions in the firewall.

A quick test of DCOM access is the DCOM test client/server app.
