Error: "Application Server does not exist"

Overview 

When you log in to Everest, the client fails to start with the following error: "Application Server does not exist".

The server event log located in C:\ProgramData\Everest\Temp\sverr.log has many of the following errors:

DCOM received error "1326"
Unable to logon to <Your Domain>\EverestCOM in order to run the server

Solution

This situation may happen after running a DCPROMO to promote your EVEREST server to a domain controller. To fix the undesired behavior, change the EVEREST and EVEREST REPORTS COM+ user accounts from <Your domain>\EVERESTCOM to <Machine's name>\Administrator.

This is the machines' local administrator account, and not the domain one.  

  1. Go to Component Settings (Click on Start > Run, type dcomcnfg and hit enter).
