[Samba] Print server failing for some users on occassion

[Mark Adams]

Hi,

Debian Lenny, Samba 3.4 (backports)

I'm currently running a cups print server with a samba front end for xp
clients to connect to. The majority of the time, this works fine -
however very occasionally a user get's a "RPC error, spool service is
not running" and cannot print. Simply logging off, and back on, enables
the printer to work again as the login script disconnects and reconnects
the printers. Nothing of use shows in the samba log for this user.

Has anyone seem any similar behaviour or have any pointers on where to
start looking?

Thanks,
Mark
