Looking for some TACACS help

When I reload my switch, I can watch the switch boot, establish PIM and BGP neighbors with my PE router.  However, if I attempt to hit Enter to sign into the rotuer via TACACS, all I get is


% Authentication failed

% Authentication failed

% Authentication failed

I get all three and a screen cycle with 1 press of the Enter key.  If I wait until I get these messages,

Nov 11 16:32:48.544 UTC: %AAA-3-DROPACCTFAIL: Accounting record dropped, send to server failed: system
Nov 11 16:32:48.544 UTC: %SNMP-5-COLDSTART: SNMP agent on host wo500-j3-1d-cpr1 is undergoing a cold start

and then press Enter, TACACS works without any problems.  I have a couple of devices in my network doing this.  The switch I am working with is a 3560, but I also have a 7606 router doing the same thing.

Anyone have any ideas ?

Thanks alot,

Brad
