I've been working on this problem for many hours at a time for over a week
now, and I'm stumped, and am hoping that someone might be able to give me
some assistance.

I have 2 users (that I know of) that have persistent connection drops. I
can see the problem as odd as it would seem, yet I don't know where it's
coming from. I have been monitoring these users connections and running
Ethereal scans on their machines and I can see when they get dropped. When I
ping -a on their IP addresses they no longer show up as their regular machine
ID's.

The machine ID's that are showing up as these people's IP address are
machines that no longer exist!!! These machines aren't listed in the Active
Directory as computers and one of them is showing up in WINS with a
"tombstoned" state, but how are they grabbing these users IP addresses?

I'm pretty sure this is a DNS problem, yet can't quite put my finger on how
these old machine names are getting propagated back into the picture.

I'm seeing other oddities in DNS like multiple machines with the same IP
address too. I have flushed the DNS, but this didn't seem to help.

In DNS there's an option to "Reload". Is this the same thing as doing
ipconfig /flushdns at the command prompt, or does it do something else?

Delete the addresses in DNS that no longer exist. Check WINS again for any
other old machines that may have been overlooked.
