samba - Dec 2004 - Odd - some users can mount /home, others cannot

LS,

What could cause the following situation:
Most users CAN connect to their /home other users CANNOT connect to their
/home and get the error 66 message.

All users concerned are in the same group and thus share the same gid.

I am aware of security stuff putting directories on 0777.

Setup is:
Win98SE
Fedora2
Samba 3.0.3-5

Funny thing is that a smclient -U username \\\\server\username
password works fine - so I can get a the data I need from the Linux side.

Error log reads as follows at log level 1:
[2004/12/16 10:14:59, 0] smbd/service.c:make_connection(771)
  fslinux (192.168.11.200) couldn't find service home

Now increased the loglevel to 10 for some detail.

A net use command on the Win98 machine reveals that the UNC mapping to the
users /home dir exists but it does not get mapped to the drive.
