SP4 and Group Policies - resolution, Kind of.

This is a story of the right hand not knowing what the left hand was
In the last few days, I have found out the following:
Scripts are now running in the new building (we just moved the whole
agency 3 blocks down the road and set up NEW layer 3 switches). It is
still the same way in the old building where SP2 and SP3 work, and SP4
The difference with the old building and the new building is that my
other co-Engineer turned off ICMP on the Switches! Even Peer to peer on
the same subnet! He did this without consulting me, or advising me of
what he had done. He does have a bit of a communication problem.
But, now that I know what is wrong, I still don't know why earlier
versions of W2K work without ICMP, and latter versions do. I know that
GPOs are supposed to use ICMP, and yet without it, they still worked
with earlier versions of W2K, not latter ones tho.
I want to thank all who responded to my post. There is something
different about SP4 and several gave me a hint of what the problem was
(we do not use Cross Domain Logins, but the fact that SP4 broke it lead
me to the sucessful conclusion).
SO I guess MS patched a hole they had all along, and for those who are
having problems, check what your routers/layer 3 switches are doing to
ICMP. If you block it, that may be your problem.
If we could get rid of some NetAPP products, we would patch to all SP4!
Unfortunately, the older NetApp products cannot understand SP3/4
Authentication, so we are stuck in a real mixed mode. Sp4 on the
desktop, and 2 on the servers. For now at least.
Marcus Ranum's new book "The Myth of Homeland Security" is now out and
is available from http://www.amazon.com/ranum In this hard-hitting
review of the homeland security business, Ranum shows us how the problem
is vastly harder than it's being made to sound, and how special
interests, butt covering, and bureaucracy are threatening to derail any
chance of making progress.
