This sounds very much like an issue we had and the problem had to do
with UDP packet fragmentation.  Perhaps you can try the following
Kerberos change.  If it doesn't work, remove it.

Add the following Value to the registry on one of the remote
workstations, reboot and try again:

HKLM/System/CurrentControlSet/Control/LSA/Kerberos/Parameters/MaxPacketS
ize     DWORD     0x580      (1408 decimal)

How much data are those two users pulling down from the domain
controllers (network trace?)  What's different about them?

I have two users amongst 50 in a remote site that no matter what PC they
login to it takes forever, but if someone else logs into that PC, they
log on quickly with no problems.

I have already run netdiag and everything passed, I have deleted the
local profile on the computer, disjoined and rejoined the domain,
changed the network card, provided a different IP address, verified I
can access \\domainname\sysvol\domainname and rebooted the PC as well as
all the domain controllers and the routers inbetween the sites.  No
ports are being blocked by anything, no changes to policies have been
done, no new servers have been made domain controllers and none have
been demoted.  There are two Global Catalogs in that AD Site,
replications is working and I have not thrown the PC out the window yet.

What else could be happening here?
