That's exactly what I had thought on WINS...and a consultant from our local networking and server source that was in here today agreed...then said that disturblingly often just putting the AD server's IP in the WINS section helps. The thing that got me on to the network being the problem was examining the regocx.log file in the local work folder as well as looking at the Networking graph in Task Manager while vantage started. On my PC...56% network utilization and login screen within 4-5 seconds. On a slow PC...1-2% utilization for 3 minutes and the log file confirmed it was taking forever to check the DLLs and OCX registrations. Once the WINS setting was made and the PC moved to the other switch it too got 50-60% utilization. HOSTS file and such are all proper. Not sure what it was causing the utilization to be throttled so badly but it was definitely happening when checking files on the mapped M: drive for the Vantage server. It could find the server fine...just not transfer data very fast.
I even had one freshly scrubbed and reloaded PC (no traces to old server or anything else) that was slow. A new NIC in it cut the delay in half...to 2 minutes. So the onboard interface was a problem but not the whole issue. Virtually all our PCs have onboard interfaces. I had wondered before about two identical PCs where one was fast and the other slow and now I wonder instead if the fast one just happened to be on the faster switch. Even if I don't find the root cause at least I have a workable solution.

Todd,
In my opinion in a true AD environment WINS should go the way of the
dinosaur. AD uses DNS for resolution. Only if you have programs that rely on
the NetBIOS namespace should WINS be needed. In terms of Order of Name
Resolution, when a host tries to communicate with another host, it first
looks to see if it is itself, then searches it local cached entries, then
the local Hosts file, then checks DNS, and lastly looks for the NetBIOS
name, by either checking LMHOSTS, WINS or by broadcasting. So as long as the
DNS records are correct it should use that before WINS.
If you needed to add an entry to LMHOSTS file then something else is wrong
with those clients. I can only assume the rest of your clients get to
Vantage via DNS.
The managed switch will help to see if the NICs on your problem PCs are
chattering or sending bad packets. I use HP Switches and I like the fact I
can use a port to monitor all traffic, so I can have a PC with some sniffer
software (I use Ethereal) to monitor traffic if I am experience problems
between hosts.
Ben Nixon made a statement that on-boards NICs should not be used and be
replaced with higher quality NICs. Though I have not had the problem you
have had, I did recently go around and made sure all my on-boards NICs had
the latest driver firmware which did resolve some other issue I was seeing.
Replacing all my on-board NICs would be somewhat costly and unless a issue
arises I will wait to make that sort of change.

A resolution follow-up for future searches on this subject.
Yes, indeed there seems to be some aspect that involves WINS...but also
involves the network switches. I have resolved the speed issue on three PCs
by doing the following....
1. Moving the client to a different switch
2. Making a WINS entry on the client that points to our AD server
Either action by itself has no effect...and I had previously tried both
independently without success...but when done together reduces login screen
delay from 3 minutes to 4-5 seconds as well as dramatically improving
Vantage performance in general.
My conclusion is that some PCs are sensitive to the switch they are running
on or perhaps a port setting on that switch. The primay user connection
switch is an unmanaged 24-port 3Com switch that has a 1Gb uplink to our
Gigabit backbone switch. I suspect there may be port settings that do not
negotiate speed correctly with some clients and because this is an unmanaged
switch changing this setting is very difficult. I'm not clear where the
WINS part comes in but as long as it helps I'm happy making the setting on
the client.
I am now ordering a new, managed, switch (HP ProCurve 2626) to replace the
3Com switch because the Gigabit switch only has one more free port. Only
remaining issue are the several slow clients in our plant that are not
served by the office switches. I may have to manually inspect their port
negotiation settings and/or bolt them down at 100Mb-full Dup at both ends.
Plus the WINS change.
Thanks again to all who offered suggestions...the answers were in there but
just required the right combo of them to be hit.

Todd,
I did not see a reference in any of the posts to WINS. Because you are on
6.1 and are having network issues without a doubt (the fact that it runs
fast on some machines and not others). I would first clean the registry of
the clients with trouble as you were indicating you were working on, and
then if you don't have WINS set up, go ahead and set it up. DNS is helpful,
but I have found in the NT4 domains that I have worked with benefit greatly
from WINS. If you are beyond NT4 domain, I don't know if WINS is as
helpful, but either way, be sure to check your hosts file and remove any
reference to the old server and maybe insert a reference to the new one.
Best of luck,
Aaron Hoyt
