please give me an advice with the following problem. We have just succesfully deployed NAC in our network but have a problem. Domain users (including administrators) are not able to change their passwords for a domain account. When I change the password for an account, the user is able to log in to his computer but Trust agent installed there doesnt allow connection to the network. And when I change the password back to the old one, Trust agent is immediately able to let the computer connect to the network and come to normal green.
So far I tried to restart the computer, also tried to shut it down for few minutes. Then I tried to restart ACS and the domain server. So far the problem is still persisting and is quite critical for our network as we are not able to change any password for any domain account.
We use the following HW and SW in our network:
ACS version 4.0
Trust agent version 2.1
Management center for security agents version 5.2
Three Catalysts 3750, IOS verze 12.2.(37)
And I have almost forgotten to note that ACS is connect to the Active directory server via Remote agent.
Thx for your support in advance.
