[Hampshire] Samba Panic

My system upgraded Samba this morning and now Samba won't run.

The problem is I can't start nmbd, the nmbd log has this in it

[2007/11/16 07:43:46, 0] nmbd/nmbd.c:main(727)
Netbios nameserver version 3.0.22 started.

I am running Mepis 6.5 which is based on ubuntu dapper, I beleive the updates
were sucurity based as that all dapper is releasing currently.

Any suggestion
