[plug] Quick DNS Query - Slow logon

[Bennett, Phillip]

It could be something to do with w2k3 needing to be a DNS server rather
than WINS these days.  I could be wrong, but I'm fairly sure it puts its
services listings into the DNS (Usually running on the PDC) This could
be confusing the clients, as they are told to point at the linux box for
DNS.  If you set up a backup DNS server on the linux box for the Active
Directory domain it might help.

Hth,
Phil.

Why guess? Try doing a few controlled tests after hours if you can, and
use Ethereal to monitor what's happening from both servers' points of
view (or, if you have a decent quality managed switch, clone all traffic
to your laptop and capture it that way).

Ethereal is available for win32:

If you compare the times that things actually happen on the workstation
to events in the packet traces, keep an eye out for something that seems
to be timing out / retransmitting repeatedly, etc, you might locate the
problem.
