I have a program on my computer that runs as SYSTEM and it is trying to launch an exe(opc server) on a remote machine x.x.x.x. But I get a DCOM error in my machine's eventviewer.

DCOM got error "2147942405" from the computer x.x.x.x when attempting to activate the server: yyyyy

I followed almost all the suggestions on the internet about opening dcomcnfg and adding users limits.default for launch and activation and Everyone,system,interactive,network from link (ftp://ftp.softing.com/pub/outgoing/opc/DCOM/DCOM-Settings-en.pdf) but nothing works.

Would anybody have nay other ideas on how to make this work.

According to MS Technet:

With my VERY limited understanding of Certificate servers you may have one of the scenarios:

  1. Client PC's are trying to connect to a Certificate server that no longer exists
  2. Client PC's have a certificate that is valid but the Certificate server no longer exists
  3. A Certificate server is broken
  4. Clients do not have the proper authority to request the Certificate

I say this is limited knowledge as I am currently trying to remove AD Certificate services from a Domain Controller and I can see that in the System event log the exact same messages are being logged as I have stopped the Certificate services to asses the impact. If I get further information I will post back.
