NW6.0 and 6.5 servers. Edir8.7.2

In a user profile under GENERAL>ENVIRONMENT>HOME DIRECTORY

Volume: DCPAH3_APPS.DCPAH
Path: Folder\Subfolder

When I login as a user, with the MAP ROOT U:=%HOME_DIRECTORY variable, I
get the following error -

LOGIN-LGNWNT32.DLL-430: The following drive mapping operation could not be
completed.
[ROOT U:=DCPAH3/DCPAH3_APPS:Folder\SubFolder]
The error code was 8804.

I understand that this location does not exist - hence the error.

Why is it trying to add the server name onto the Volume/Path?
It should be [ROOT U:=DCPAH3_APPS:Folder\SubFolder] - and if I put the
specific map command in the profile instead of using the HOME DIRECTORY
variable - it maps fine.

This is driving me nuts - I cannot use the Home Directory variable - I have
to map the drive to the specific location in every user profile. Any help
would be greatly appreciated.

thanks
