On my single Win2000 Domain controller, I was getting a JRNL_WRAP_ERROR and I now find stupidly followed the instructions given in the error and created a "Enable Journal Automatic Restore" registry entry and set it to "1". At this point the Domain controller disbled the SYSVOL share and dispite hours of waiting, never re-enabled it so I have no Domain Controller.
Further reading has hinted that I should not have performed this step.
This machine was setup by my predecessor to also be our Exchange 2000 server and backup.
How do I re-enable FRS and get Exchange back up?
