[Samba] (no subject)

[Coen]

LS,

I've been trying to set up Samba 3.0.20b on a Debian server. It all works
ok, except for IIS 6.

I am using a W2K3Std Server to connect to a Samba domain. This is
necessary because of the way IIS authorises it's users. Every website has
it's own user and uses that user to log on to a home directory in which
the website resides. So far, everything is okay.
When I browse to a website, I get the site presented in no-time. If I let
the site idle for a while (say 5 mins or so at least) it's dead... "no
such file or directory"
Stopping and restarting the website in IIS manager works immediatly, but
it is not the way I'd like to work (:P)
When I check the samba errorlog after refreshing or visiting a 'dead'
site, I see the next line:

[2005/10/28 10:55:43, 2] smbd/sesssetup.c:setup_new_vc_session(704)
  setup_new_vc_session: New VC == 0, if NT4.x compatible we would close
all old resources.

Does anybody have any idea what is causing this problem?

Thanks
