PostgreSQL version: 9.1.4
Operating system:   Windows Small Business Server 2008
Description:=20=20=20=20=20=20=20=20

While registering the Postgre service no problem appears. If i wanna start
the registered service, there appears a windows message that the
postgres.exe had been crashed. I tried to take another version of postgresql
but same problem.
Before using 9.1.4 i used version 9.0.2.
Are there known windows small business server 2008 problems?
