samba - Mar 2004 - Samba-3.0.2a and pathwork server smbmount problem

When I tried to mount a share folder from a pathwork vms server, I get
the message 'protocol initiation failed'. I get this message since
I've
upgrade to the kernel version 2.4.25 and to samba 3.02a.

I don't get this message with my old config (samba-2.2.28a and
kernel-2.4.28). Is somethings has hanged with smbmount between these 2
release ?
