you need everything in the $PGDATA directory.     On my system here, its
D:\Postgres\8.4\data  but of course, your mileage may vary.

Hmmm. So, what's the output of running

    NET HELPMSG 3534

?

Have a look in the Postgres log - there's often (usually?) information
there that doesn't get sent to the Windows event log.

It's probably in $PGDATA/pg_log, unless you changed something in the
logging configuration.

Waqar,

yes. that says that the windows-user your PostgreSQL Service is
running as has no write priv on the data directory. Check your file
systems permissions and allow writing to the data directory for the
user your PostgreSQL service runs as.

You need the data directory, and the service user "postgres" needs to
own it's contents.   consider using runas and xcopy.
