samba - Aug 2009 - cupsaddsmb not working after upgrade to Lenny (rpcclient -> WERR_INVALID_PARAM)

Dear list,

   I've upgraded my server from Etch to Lenny and now the printer (HP 
LaserJet 6P) does not work any more through Samba.

Printing a testpage via http://server:631 works perfectly so I skip 
giving details about the CUPS setup.

Also lpstat reports the printer working
# lpstat -a
HP_LaserJet_6P accepting requests


I tried to rerun cupsaddsmb. The driver files are copied to the 
print$-share (I can see them in /etc/samba/drivers) and also the first 
RPC call 'adddriver' is reported successful. The second one
'setdriver'
ends with 'WERR_INVALID_PARAM', see output:

That does tell me absolutely nothing :)

Any idea?

Thanks,

Another thing I found out:

When calling the 'setdriver' command with rpcclient the syntax is
setclient <printer> <driver>

I guess that means to assign a driver to a printer.

I furthermore read in Google that samba should find CUPS printers 
automatically, at least after a restart.

Nevertheless, 'enumprinters' does not return any printers:
# rpcclient localhost
Password:
rpcclient $> enumprinters
No printers returned.

Ok. After trying hours the solution of the problem was the simple 
Windows method of rebooting the server :(
