Hi,
I'm trying to configure an NPS as a RADIUS server for a customer, I've never set one up before and after a week of troubleshooting from where I am to where the customer is (Across the country) we are finally getting rejected instead of no response from the server at all (yay).
The issue I have now is event ID 4401 Domain controller for "domain" DIR is not responsive. NPS switches to another DC.
Then I get event ID 4400 There is an LDAP connection for domain controller "domain" is established. Each time it hops between different domain controllers. This is a large domain with many DC's...
The NPS server is a member of the RAS and IAS group in activate directory and is on the domain...
Any ideas?
EDIT:
I would also like to add that I am getting access-request and access-challenge and access-reject while watching wireshark when someone tries to connect. The users are added to the security group that is added to the network policy conditions.
