My trust to two nt resource domains quit working last
week. Is there any body else that has the same problem?
I have been workink on this with MS and still no
resolution. Thanks in advance.

It's actually pretty common but there a number of
reasons the trusts quit working e.g., Cable, NIC,
routing, name resolution, or something blocking the
necessary netbios ports like a personal firewall ect.
ect. Can you give us more details of what symptoms
you are seeing and what you have tried unsuccessfully?

With MS on the phone we broke the trust and recreated with
netdom. Netdom would not complete successfully. I do get
the W2k domain to trust the NT domain. When I try to map
from the w2k AD domain I get The trust relationship
between the Primary and the trusted domain failed. I get
admin alert messages (on w2k) saying message from NETLOGON
at"NT machine"

Failed to authenticate with \\W2k DC, a windows NT domain
Controller for W2k.

I just reset the "RestricAnonymous" on w2k DC's to 0.

Every thing is on the Lan on one net sharing the same Wins
server.

Everything pings out.

What error did you receive while attempting to use netdom?
Open a dos prompt immediately after unsuccessfully using
netdom to complete the trusts and run nbtstat -c and verify
the following netbios names are in the cache without conflict
domain names 1b, 1c and at least computer names 00, 20, 03
pertaining to the PDC/PDC emulator in the remote domain.

I ran the netdom command and it ran successfully this
time. I had all the netbios names in the cache. What
else can I check?

So your problem is intermittant or do you see current
5719s on the DCs in either domain?

I see a couple on both domains on 4/15 which is when my
problem started. I am also getting allot of 3210's. The
problem does not seem intermittant. I am unable to map to
the trusting domain (NT domain). Yesterday I ran
nltest /sc_query:w2k from the nt domain and got an
error_access_denied. Status 5 0x5. thanks for the help.

Have you checked NTLM compatibility?

I have knock down the AD DC's security policy to allow for
downlevel clients. What is the best way to check NTLM
compatibility?

Compare the following on the DCs in each domain:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\LMcompatibilityl
evel

It was set to 1 when I set it to 0 I can map from the
console. Do you know what AD policy controls that reg
setting?

Yes. I would think the trusts were not properly established..

Well late yesterday after a reboot and recreating the
trust with netdom, trust NT to W2k is working. It was the
Lan Manager Authentication Level. I had it set to send lm
and ntlm -use ntlmv2 session if negotiated. I set it down
to send LM & NTLM responses. I have had it set the latter
for a long time, I was suprised that it stopped working.
I run SUS and some security patches rolled out last week.
I think the patches must have change something with this
setting. With viruses taking advandage of security
vulnerabilities so quickly anymore. I hate to miss a
security update or have to uninstall the update. Have you
heard of any others having this problem? Thanks for your
help. I love this newsgroup.

No actually I haven't heard a whole lot regarding this particular
issue. I suppose it's possible the update may have reset the
NTLM parameters as a security measure..
