does the service start after setting archive_mode to off again? Which
version of PostgreSQL? There was problem with fragmented RAM/virtual
memory that prevented PostgreSQL from (re-)starting sometimes. So if you
don't have an actual PostgreSQL try rebooting the system ...
What do the Windows system logs say? Do you have anti-virus software
running? Google for the error code ...
Good luck,
Peter
