I have one computer on my client's NAV network that keeps losing the connection to the NST. The other computers on the network work fine, and I have used the exact same network path (servername:7046/DynamicsNAV) for both. What other things can I check?
I do not believe it is a authentication error as I have the user added to the database - and usually it says "You do not have permission to run Dynamics Server" when it is an authentication error.
ADDITIONAL INFORMATION from the event log:
"the security system detected an attempted downgrade attack for server host/192.168.1.160. The failure code from authentication protocol Kerberos was "there are currently no logon servers available to service the logon request"
The Security System could not establish a secured connection with the server host. No authentication protocol was available.
Also when I try to log into Classic using Windows Authentication Mode I get:
Cannot generate SSPI context State ID HY000"
