Unable to start the RAS service

P

Pal

It was all working fine in my W2K server. This morning
noticed that RAS user was unable to connect to the RAS
server. The event log shows, Event ID: 20152. The current
configured authentication provider failed to initialize
successfully. The parameter is incorrect. Tried several
times to restart the service but no use. Also deleted the
RAS configuration and recreated but back to same errors.

I am not sure how to proceed on this error to get the RAS
service up and running. Thank you in advance for your
help.

Authentication provider failed to load and initialize. This could be because

(1) If configured for RADIUS authentication:

a. check whether the rasrad.dll file exists under
%SystemRoo%\system32.

b. RADIUS server name is misspelled or RADIUS server is not running.

(2) If configured for Windows authentication:

IAS Server initialization failed
