Using %UserDNSDomain% in PRF file --> Issues`

[Nathan]

Trying to use the %USERDNSDOMAIN% env variable for Outlook 2003 setup
with some issues. I've updated the prf file we use to setup the
intial outlook profile and then run outlook, but end up with an MSI
error regarding an Installation failure.

Has anyone tried to use this variable successfully? I know it works
if I manually create the profile and use the varable as part of the
servername field, but just having issues with the auto prf side.

TIA

Nathan
