postgres service does not start after windows restart

hi,

  i recently installed postgres8.0.4 on my comp. my OS is Windows 2000. it installed postgres database as service and made an local account on my comp.

but when i restart my windows i am unable to start the service. the service start is set to automatic but it doesnt start automatically and when i try to manually start it it gives an error

 

Could not start PostgreSQL Database Server 8.0 service on local computer

Error 1069: Service did not start due to logon failure

 

Kindly guide me as to how to restart this service after a windows restart

 

thanks and rgds
