Password reset recovery problem with cisco 827 router.

Hi,
I have been able to gain access to privilege mode by turning of the router and:
Press Break on the terminal keyboard within 60 seconds of the power-up to put the router into ROMMON
rommon 2 > reset
<----snip---->
Router(config)#enable secret <password>
<----snip---->

The password recovery technique is in this document.
http://www.cisco.com/warp/public/474/pswdrec_827.shtml
My problem is that after reboot the new password does not seem to work so I always have to always reboot to rommon2 to gain access.  After normal reboot, when I try to get into exec mode the router asks for username.  There are three listed in the show-config along with encrypted passwords, and none seem to work.  It is not even clear to me which password I am reseting.  Does anyone know if there is a way to change the username and password or a work-around to avoid this altogether?

once you have gotten enable rights what about line vty 0 4 passwords? I am assuming you are consoled?

what you want to do is the following

once your in the router do
copy start run
then enable secret <password>
then configuration-register 0x2102
then end
wr mem

and then reload

Thanks
Scott

scotty is right, it sounds like your changing the wrong password

Can you post a show run of the unit once you have access via romon to show the password config and if it is doing tacacs.

Thanks

This link will not help you with an encrypted secret ..... with that said .... it will work with type 7 passwords.

Thanks

it will at least give him access to user mode, also the decrpyted type 7s may give a clue as to what the secret is.

Scott, it is very easy to act smart and dismiss things, but i think this will help him as he cant even access the exec mode.

cheers

Thanks!  
 I used the website above to decrypt and I got plausible sounding passwords, none of which were mine.  This may give me enough access to change things.
As per Scotty_cisco's request, I can not post for a while because I do not have access to the router right now.  
I do have this from the last visit however.
-----------------------------------------------------------------------------------------------------------------------------------
password 7 6xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 login authentication userauthen
 transport input none
 stopbits 1
line vty 0 4
 exec-timeout 30 30
 privilege level 5
 password 7 1xxxxxxxxxxxxxxxxxxxxx
 login authentication userauthen
---------------------------------------------------------------------------------------------------------------------------------------


As per which password I reset.  I followed the instructions from the link above exactly as written.  I even did it more than once so I am assuming you can tell which password those instructions are resetting.  The instructions do not say which password is reset, but I can get into exec mode through the process described below.
