Lost local admin password ck 10-04-2005

Hi,
I lost my local administrator password. It is stand alone windows server
2003 standard edition with SP1.

"Administrator" is the one and only one userID with admin rights.
Any way to get back the password without reinstall the OS?

thanks

do you have access to the server? do you want to reset the password to something
you know, or do you want to recover the old password, those are two different
things.

If you have physical access to the box you can reboot it with for instance
ERD commander from Wininternals and reset the admi password. (look out, it
will corrupt the certificates that are present in the personal store of
that admin (including de recovery agent certificate)

there are several other tools that claim to do the same thing, but I had
bad experiences with for instance te famous linux boot flop that claims to
do the job, but it corrupted my registry in a sence that I could not promote
my machine anymore to a DC or demote it from DC, and it was consistent in
doint so.

s first test the tool you are going to use first on a similar test OS.

good luck

Eric

In This case I should try to get hold of a ERD commander CD, a BartPE disk
or something like that. you can get ERD commander from www.wininternals.com.
this is for me the first choice in these situations.

I do not know what the linux Boot floppy does when you enter a blanc password
for the admin.

can you physically logon to the server with another account?

In that case you might want to try the following first:

open a command prompt and type:

at xx:xx /interactive cmd.exe

where xx:xx is the time in two minutes. if it says: added new job.....
you in the clear, because now you just have to wait for the commandbox to
open and do the next thing:

net user <username> /add
net localgroup administrators <username> /add

with this you added a temp user and added this account to the admins group,
you now can logon with this accoutn and reset teh password of the original
admin.

good luck
