Firewall Client on NT4/9x cannot authenticate - 20.Oct.2005 5:49:00 PM

We are completing a migration from an NT4 domain to a Win2k AD domain. Most computers have been upgraded to Win2k or XP. We have a few computers doing specific tasks that cannot be upgraded that are running NT4 or 9x.

Win2k and XP computers work as expected. I have 2 basic groups -
Internet + email
Email + VPN (to partner company)+ allowed websites (for updates)

On ALL NT4/9x machines I cannot authenticate to the AD domain. I get a red x by the client and a message saying:

Disabled: Cannot Authenticate to ISA Server %servername%

I have looked all over the web, google, newsgroups and this website with no luck. I am assuming that my ISA configuration is correct because it works on the XP/2k machines.

Is there anything special that I need to do for the older computers/OS's?

Oh, I have ISA 2004 sp1 on a Win2k Box.

Thanks.

First of all if i`m not mistaken - new firewall client didnt works with NT/9X. You need old client for this machines - from ISA2000.
On firewall client settings on ISAserver you need to check option "allow older clients to connect to the IsaServer" or something similar.
Make sure your NT/9x sees AD and all users policy propagate for them correctly.
It should work just fine.
As a quickaround option you can permit access for selected PC`s as computers, but its weakens your security.

Thanks for the quick reply skiril.

I'd like to give that a try except...

where to get an ISA 2000 client?

I can't find one @ technet/microsoft.

Thanks again
