Initdb failing for no apparent reason in 8.0.0beta4 on windows

Hello,

We have been using postgres 8.0.0beta4 successfully on various windows
machines for a while now, but we have run across a particular windows
machine of one of our customers where initdb.exe is failing with an exit
code of 1 for no reason that I can determine. The machine is running
windows 2000 (sp4, version 5.00.2195). I have tested in-house
successfully on windows 2k (sp4, v5.00.2195 as well), windows 2k3, and
windows xp pro (sp2).

We created a non-administrator account (named "enetaware") on the customer
machine and given it "log-on-as-service" privileges (we ultimately run
postgres as a service using this account). We have the postgresql bin,
lib, and share directories installed on the customer machine in
"C:\Program Files\EmprisaNetworks\E-NetAware\postgresql". We execute the
following command while logged in using this account (-d and -n options
added temporarily for debugging):

initdb.exe -d -n -U ena -L "C:\Program
Files\EmprisaNetworks\E-NetAware\postgresql\share" --locale=C

The output from this command is:

Running in noclean mode. Mistakes will not be cleaned up.
Running in debug mode.

This user must also own the server process.

The database cluster will be initialized with locale C.

creating directory C:/E-NetAware-Data/db ... initdb: failed

The exit code returned by initdb is "1". Any ideas why this would be
failing? I didn't see any similar report about this in the mailing list
archives. My next step is to recompile initdb.exe and put in more
temporary debug print statements and have the customer retry it, however
that may take a while.

Thanks in advance.
