Client 2 SP3 IR2 MAP ROOT H:=%HOME_DIRECTORY not working

Hi,

i'm testing Client 2 SP3 IR2 on Windows 7 Pro SP1 32 bits. After logon the loginscript stops because the %HOME_DIRECTORY cannot be mapped.

LOGIN-LGNWNT32-430: The following drive mapping operation could not be completed.
[ROOT H:=SERVER/VOL1:\USERS\OU\USER]
The error code was 8836

Other drive letters work oke because they don't use a Novell variable to get mapped.
Drive U: = SERVER\VOL1:INSTALL\DIRECTORY works
Mind the / and the \ difference behind the servername. I think the / at the H: drive is teh issue here.

Any ideas?
Regards,
Patrick
