postgres in windows xP

Hi

I have been trying to get postgres in windows through cygwin. No success yet. I followed all the instructions in postgresql-7.4.5 step by step. But the last a few steps, particularly, in step 9, cygrunsrv –S postmaster  doesn’t work. I could not start postmaster as service at all. I have added postgres to log on as service in secpol.msc. I can also see postmaster in service, in postmaster’s property, log in tab, I can also see postgres.

Ok, here are a few messages, I got, I tried both commands cygrunsrv and net start.

When I run as   admin user , who got admin right, I got these errors

admin@laptop ~

$ cygrunsrv -S postmaster

cygrunsrv: Error starting a service: QueryServiceStatus:  Win32 error 1062:

The service has not been started.

admin@laptop ~

$ net start postmaster

The postmaster service is starting.

The postmaster service could not be started.

A system error has occurred.

System error 1067 has occurred.

The process terminated unexpectedly.

When I run as postgres user, who got limited right, I got these

postgres@laptop ~

$ cygrunsrv -S postmaster

cygrunsrv: Error starting a service: OpenSCManager:  Win32 error 5:

Access is denied.

postgres@laptop ~

$ net start postmaster

System error 5 has occurred.

Access is denied.

Any Help please,

With many thanks

James
