Error code 1063

We have PostgreSQL 8.1 running on Windows 2000 for a few
weeks now, when we try to start the service, it could not
start claiming no error returned. So, I go to the command
prompt and run the following:

"C:\Program Files\PostgreSQL\8.1\bin\pg_ctl.exe" runservice
-N "pgsql-8.1" -D "C:\Program Files\PostgreSQL\8.1\data\"
pg_ctl: could not start service "psql-8.1": error code 1063

I tried googling that error code, but come up with nothing.
Can someone tell us what this code means?

C:\> net helpmsg 1063

The service process could not connect to the service controller.

You can't use "runservice" from the commandline, only from the service
control manager. If you want to start it with pg_ctl, just use "pg_ctl
start".
