Need some help getting started

I'm using Win XP Home

I'm stuck on step 9 of these instructions:

http://www.tishler.net/jason/software/postgresql/postgresql-7.3.4.README

It doesn't say whether I should run it as "postgres"
or my "Dan" account, but neither seems to work.

1) As "Dan", I get:
cygrunsrv: Error starting a service: StartService:
Win32 error 1069:
The service did not start due to a logon failure.

and there's an application Event with these comments:

The description for Event ID ( 0 ) in Source (
postmaster ) cannot be found. The local computer may
not have the necessary registry information or message
DLL files to display messages from a remote computer.
You may be able to use the /AUXSOURCE= flag to
retrieve this description; see Help and Support for
details. The following information is part of the
event: postmaster : PID 3460 : starting service
`postmaster' failed: execv: 1, Operation not
permitted.

2) As "postgres", I get:
cygrunsrv: Error starting a service:
QueryServiceStatus: Win32 error 1062:
The service has not been started.

and there are the following two application Events:

The description for Event ID ( 0 ) in Source (
postmaster ) cannot be found. The local computer may
not have the necessary registry information or message
DLL files to display messages from a remote computer.
You may be able to use the /AUXSOURCE= flag to
retrieve this description; see Help and Support for
details. The following information is part of the
event: postmaster : PID 4044 : starting service `'
failed: redirect_fd: open (1,
/var/log/postmaster.log): 13, Permission denied.

The description for Event ID ( 0 ) in Source (
postmaster ) cannot be found. The local computer may
not have the necessary registry information or message
DLL files to display messages from a remote computer.
You may be able to use the /AUXSOURCE= flag to
retrieve this description; see Help and Support for
details. The following information is part of the
event: postmaster : PID 2128 : starting service
`postmaster' failed: execv: 1, Operation not
permitted.

BTW, as "postgres", I was getting another error before
giving the postgres user a non-blank password. You
might want to add that to the instructions.

Thanks in advance for any ideas.
