We are experiencing intermittent problems with Radiator using AuthBY NT.
Maybe this is something that one of you has seen before.

Basically we have requests coming from a pix firewall to an NT box (a very
lightly loaded BDC) running radiator. The users type in their NT usernames
and passwords, which are then checked against the BDC. If the credentials
are ok and they are a member of a particular NT usergroup then the request
is accepted. This works great much of the time.

At least once a week authentication stop working. When I look in the
radiator log I see "NT CheckPassword failed: 53: The network path was not
found.". This seems to be saying that radiator cannot talk to the BDC. This
seems a bit weird to me since radiator is running on the BDC! There is
almost no load on the server so I can't see it not being able to respond to
the requests. Has anybody else seen this behaviour?

I have included below the relevant parts of my config file and a trace 4 log
of a user experiencing the problem.



Thanks very much,



Ash.
