Slow Network Logon on NT 4.0 Network

[Robert Vorwaller]

I recently setup 2 Compaq EVO 2.4 Gig computers with
windows XP Professional on our network, and when first
setup the computers connected to our network in about 8
to 14 Seconds. I did the first update on the web to
service pack 1a thursday 7/4/03 and the logon time jumped
85 to 90 seconds. I know it is looking for something but
I don't know what. We are still on a NT 4.0 Network, and
have a WAN connection to multiple sites. I am guessing it
is trying to find an active directory, or something.
Yesterday I noticed that the Service pack 1a was removed
and reverted back to sp1 on the update site. I thought
that it was having a problem and so I did a fresh install
and then installed SP1 and ended up with the same
symptom. I did an install with a corporate version of XP
Professional and then upgraded to SP1 from the web and It
did the same thing. I installed the compaq version back
on using the restore cd and used the SP1 cd that came
with the computer and It still worked fine. I then went
to the update site and installed the security fixes and
the computer then went back to 85 to 90 seconds to logon
to the NT 4.0 Network. Does anyone out there know what
is happening???????
I have two older EVO computers running XP Professional
that have been keeping up with the service packs and
patches and neither one of them is having this problem.

Why is XP running slower while logon

When I login into a Windows 2000 active directory from a new xp pro machine
the login in is extremely slow. After logged on, everything works fine. But
other windows versions don't have this problem.
A: This is almost like name resolution issue. Comparing with previous
versions, XP is heavily dependent on DNS to find DC. If the DNS is
configured incorrectly, XP will take longer time waiting for it to timeout
before it tries using NetBIOS. Make sure
1) The DNS setup correct and have the server information.
2) XP clients can find the DNS server.
3) XP machine's DNS server is pointed to your internal DNS server rather
than your ISP's DNS server.
4) Make sure no errors on logon scripts or GPO's that could be causing
the delay.
5) Check any errors on event viewer.
6) Disable NetBIOS on the interfaces that client will not use.
