Locked out my Server Box

I am in a sticky situation...

Basically, I am moving the server IPs from one range to a new one.
Now Ive just gone through ten servers when I hit this particular one.

After getting to it, I realised, what the hell is this password for Administrator (Windows Server 2003 x64 Edition). I have absolutely no idea. After an hour of thinking, I realised I still have no idea...

But then I realised Windows Vista MSTSC saves passwords for you if you allow it. I went through every IP configured for the two NICs for this box and finally found one I saved the password on. Great news... you would think, but the problem is, even though I am in, what can I do to change the Administrator password?

I will lose this IP in about 6 hours, Im moving networks and I cant keep the current IP for this box for any longer then this, which means I need immediate answers before I lose the box altogether and I really cant be bothered to travel to the DC if it can be avoided.

Anyway, Im thinking either, there is a way to get the administrator password... or I create a new account with full administrator permissions.

Can anyone think of a way to get access back to the box after the IP is dropped and I cant use the Vista remember credentials?

Thanks

 

Dont worry,

I decided to take the risk of losing data and reset the password through the lsusrmgr

Hopefully everythings okay.

 

It should be fine.

lusrmgr is the usual way for admins to change the password for everyone, including themselves. the changing of passwords at msgina is only for individual users.

 

Well originally I didnt want to tak the risk, but then I realise it makes no difference if anything is damaged, worst case scenario, I have to go up to the DC and repair things, which I would have had to do anyway.

Looks like it worked anyway,

Linux has various methods without loosing any data but Windows has only
lusrmgr to change the admin login.
