PostgreSQL Problem on Windows XP

Hello,
I attempted to install PostgreSQL on Windows XP according to the
procedure in http://www.postgresql.org/docs/faqs/text/FAQ_MSWIN

There seems to be a problem with the ipc daemon, as the following happens:
=========================

Owner(at)Trick ~
$ ipc-daemon2 &
[2] 5152
[1] Exit 1 ipc-daemon2

Owner(at)Trick ~
$ initdb --pgdata=/usr/local/pgdata -W -E LATIN1 -d
Running in debug mode.

initdb: internal variables:
PGDATA=/usr/local/pgdata
datadir=/usr/share/postgresql
PGPATH=/usr/bin
ENCODING=LATIN1
ENCODINGID=8
POSTGRES_SUPERUSERNAME=Owner
POSTGRES_BKI=/usr/share/postgresql/postgres.bki
POSTGRES_DESCR=/usr/share/postgresql/postgres.description

PG_HBA_SAMPLE=/usr/share/postgresql/pg_hba.conf.sample
PG_IDENT_SAMPLE=/usr/share/postgresql/pg_ident.conf.sample
The files belonging to this database system will be owned by user "Owner".
This user must also own the server process.

The database cluster will be initialized with locale C.

=========================
Any suggestions? I have a gigabyte of memory and only 465 MB is being
used, so there shouldn't be a problem with memory allocation.
Thank you,
