smbfs: failed to load nls 'iso8859-1' error

[crisponions]

I recently upgraded to samba 3. Since then trying to mount my one of my windows shares I get the following error when tryin to list the folder, stale NFS header. The error in dmesg is, smbfs: failed to load nls 'iso8859-1'. I have checked it is enabled in the kernel. Another one of my windows shares mounts fine.

The windows domain was recently upgraded to win 2k3. I had to do a bit of tweaking to samba to get it to see the shares (they are on a domain controller). But previous to this both shares mounted correctly. Any ideas as to what might be wrong?
