PostgreSQL 9.0 service error : The service did not respond to the start or control request in a timely fashion.

[tuanhoanganh <hatuan05@xxxxxxxxx>]

Yesterday, my postgresql 9.0 service run well with user postgres. But today when it start, it have error "The service did not respond to the start or control request in a timely fashion."
When I change my user start service to "Local System Account" and check "Allow service to interact with desktop", postgresql service start well.

I have install dotNet framework 3.5 SP1 (include dotNet framework 1 Sp 1) on windows 2003

How to fix error.
Thanks in advance
