Password Recovery

I recently aquired a 4506 with all the module. When I powered it up it went through all the boot up sequences and passed and then prompted me for a username and password. Since I didn't know what these were I decided to reset the passwords in order to get in.
When I go through the password recovery procedure per cisco document #21229 I get as far as issuing the "show running-config" command and I get a "authorization failed" error from that point forward.

Switch>enable
Switch#configure memory

Uncompressed configuration from 7582 bytes to 37341 bytes
505CPW-AMC-7-ASW1#show running-config
% Authorization failed.

505CPW-AMC-7-ASW1#write terminal
% Authorization failed.

I looks like they had AAA setup, and aaa authorization commands enabled. so i would say don't load the config from start to run and just start a new. unless you need the config then tftp the config over to a tftp server.

Console in and hit 'pause/break' key during boot.
When you get the 'romon' prompt type 'confreg 0x2142' then power cycle the router. This will cause it to ignore startup configuration.
Once you're in you can do a 'sh start' which will give you the existing config. Take from it what you need and start from scratch.

NOTE: Before you try to save any configuration, in configure terminal mode run 'configuration-register 0x2102' otherwise nothing will take hold.
