NEC UltraMail RPC Server Unavailable

The scenario is when starting NEC UltraMail / Voice Mail Administration version 3,0,1,11, you receive errors related to the RPC server being unavailable, and MS Events like "DCOM was unable to communicate with the computer 'YOURCOMPUTERNAME' using any of the configured protocols."

MS will suggest you check a DCOM registry setting to verify what protocols are available, and the entry will be empty. Nice.

That has nothing to do with it.

Search your registry for "DOSGui". You should find an entry like "HKEY_USERS\bunch of cryptic stuff\Software\CTL Inc.\DOSGui\SaveSettings".

The VMSMachineName REG_SZ there must equal your machine name. Do an IPCONFIG /ALL and if your name is MyComputer.MyDomain.Local, enter the "MyComputer" portion only. Change the VMSMachineName to your real computer name.

If your IT department likes to re image machines rather than troubleshoot little application problems, they may be changing machine names or leaving residue from the image sources in your new image. This will break UltraMail.
