Hi,
Can't you connect through console and do a debug tacacs, on a router
that is not heavily utilized?
If you happen to be experiencing timeout on tacacs auth, try to restart
CSTacacs on the ACS.
If you go to services.msc (you said it was a windows box), what is the
status of CSTacacs?
Is this happening only to one router, or to all of your infrastructure?
Also check under system configuration-logging, that you are in fact
logging failed attempts.
Re-check your windows firewall status or any other firewall you may have
installed (like CVPN Client)
HTH

Have you looked into the 'Reports' -> 'Failed Authentications' (might
not be
exactly these names). You should see all denied authentication attempts
and
the reason for the denial there. You also need to set the router up in
the
network groups as others have suggested.
If you do a 'sh tacacs' on the router you should see if a tcp session to
the
server exists.

Just wondering:
Your acs logs should not be blank Unless you are not logging anything.
You
might
want to turn them on. If they are blank then it's like the service is
not
listening to requests or getting the request. Under reports and
activities
what
does the appliance status page state for the basic configuration
(tcp/udp
ports
open). Are the ports open?
Are you filtering any ip addresses in the acs client setup?
