if the cifs.ko was for 2007, then post exactly what you did.

The exact commands, the exact error messages.

Then it is possible to work out what went wrong and what to try next.

cifs is the term for the microsoft implementation of file sharing (I think that's what the fs in cifs is). Samba is an implementation of it too.

Samba uses cifs, Windows uses cifs, other things do too.
