Connect to 2.0.2 from 1.9.18

[Pedro Fradique da Silva]

Hi all,
I'm trying to connect a SUSE6 box with Samba 1.9.18 to a RH5.1 Server
with Samba 2.0.2.
I receive this error:
Mount error - Invalid argument
The commandline is: smbmount //rh51/public /mnt/pub -Uuser
It worked fine untill we upgraded to 2.0.2.
Can anybody help?
TIA,
Pedro.
