After a power shortage, nobody could connect to the Samba shares of a Debian Linux server, and a look at “top” on the Linux server showed that the winbindd process used 100% cpu.

The solution was easy:

/etc/init.d/samba stop
/etc/init.d/winbind stop

a kill -9 <processnumber> to the running winbindd process.

Find and remove the gencache.tdb file (/var/lib/samba/gencache.tdb on my Debian server).

/etc/init.d/samba start
/etc/init.d/winbind start
/etc/init.d/samba stop
net rpc join -U administrator%<admin_password>
/etc/init.d/samba start

This fixed the problem.

Configuration: Domain master is a Windows SBS 2003, main file server a Debian Linux Lenny server using winbind as primary autentication mechanism.
