Windows 2003 server installation issue

Hello Folks,

   I am facing an issue starting postgresql using windows service when my user belongs to Administrator group.

   I applied patch from following thread to 8.4.1 source code and it seems to be working with every windows operating system except Windows 2003 .

   http://archives.postgresql.org/pgsql-bugs/2009-10/msg00128.php

  I get an error as below

  OpenProcessToken : error code 5 when I start as service but if I start postgresql from command line as “pg_ctl start –D ….” Then it starts up.

 Please provide some input on this. 

Thanks & Regards,

Vikram
