Still the 1069 logon problem

Hi!
I've been searching the lists and the internet for a while but I didn't find
a solution, how to cope up with the problem.
I'm using Windows XP professional, want to have postgres as a service and
run on startup.
But: it doesn't start.
When I want to start it manually, I got the well-known error message:

Could not start the PostgreSQL Database Server 8.0 service on Local
Computer.
Error 1069: The service did not start due to a logon failure.

I really have to solve this problem, it's quite urgent!

I hope somebody can help me, how to solve this problem!

Bye & thanks,

Fritz
