Windows 10: NPS server service is not starting

NPS server service is failing to start

NPS bug on windows server 2019

I installed 2 new windows server 2019 with NPS and VPN and in both servers I have the same error.

Cannot initialize the Routing and remote access service due to an error in the NPS service:

RAS log: Event 20153: The currently configured accounting provider failed to load and initialize successfully. The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server
to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.

NPS log: Event 4404:

NPS cannot log accounting information in the primary data store (C:\Windows\system32\LogFiles\IN1902.log). NPS will continue to process connection requests without logging accounting information in this data store. Error information: 22.

The NPS has default accounting settings writing logs to a file not an SQL database.

I have tried deleting the log file and restarting the NPS service but I get the same error.

I can solve the issue when i disable Logging failure action: "If loggin fails, discard connection requests", in Log file properties in accounting.

After that change the RAS service starts sucessfully.





I think this is a bug.

 

Belle & Anna Radius Negotiation (NPS>PEAP)

It seems its becoming a habit for me to solve my own posts..



The actual result came from a Nokia engineer, which solved the problem completely.



http://msdn.microsoft.com/en-us/library/ee942815(v=VS.85)

• On the NPS server start regedit.exe
• goto HKLM>System>CurrentControlSet>Services>Rasman>PPP>EAP>25
• Add DREG value BypassNegotiation
• Set the value 0 to 1.
• Restart the NPS Server Service

SOLVED.

 

NPS Server and DHCP Problem

We are running Windows Server 2012/2016 Network Policy Server - With 802.1x authentication, when NPS submits a query to a Domain Controller with a computer name, does it trigger the Windows 10 client to request an extension to the leased DHCP address?
