[Samba] Problems with Samba <=> CUPS and Samba <=> Windows

There are two problems I have with Samba

My system: Suse Linux, Kernel version 2.6.12.5, Samba version
3.0.20-0.1-SUSE

1st problem: If I put my outlook.pst on my Samba server and tell my =
Outlook
to use the network path to it, it screws up after some weeks. The file =
is
about 240 MB large but I don't think that does matter. I don't have any
other files having problems.

I already tried to disable kernel oplocks and to map the path to a local
drive but it didn't help. What can I do?

2nd problem: I use CUPS with Samba. If I try to cancel my printjobs via
Windows spooler, it comes up with an "access denied" notice. Looking =
into
the error log it reads: cancel_job: "anonymous" not authorized to delete =
job
id 156004 owned by "M-Y-U-S-E-R-N-A-M-E"!

What is wrong? My jobs get my username on it, but my cancel commands =
don't?

I'd appreciate any useful help :)

Thx in advance

Manuel
