Mount problem please help!

[UDP-Jack Bluebird]

I have got Samba (2.0.7) running on a fresh Red Hat 7.0 install.  I can do a
smbmount and mount a w2k share on the Samba box. But when I try to mount a
old LM2.2 share I get the following error right after the password prompt:

mount.smbfs: ioctl failed, res=-1
Could not umount /share: Device or resource busy
mount.smbfs: exit

There is also a message on the console that reads:

smbfs: protocols older than NT1 are not supported
smb_retry: no connection process

This setup works fine on samba 2.0.6
Any Ideas?
Thanks,
