I have a PC on a domain but I don't know the local administrator password.
I cannot logon to the PC by using a domain user because the trust is broken between the PC and the domain hence wanting to logon locally.
I'm not sure how to recover the password ot how to logon.
HELP!!
thanks

Here you go.  With this you can blank out the Admistrator password.

We can't help with Password Recovery as that would leave the account compromised without any evidence of entry - but we can give you advice on resetting.

The best tool I've found is http://pogostick.net/~pnh/ntpasswd/ which edits out the password from the security hive.  You need to burn the .iso to a bootable CD and then follow the instructions on screen (info on the linked page) remember to save your changes before exiting the utility.

Similar functions are available on boot CDs like UBCDWin

Scroll down about half-way to the "Offline NT Password & Registry Editor (v080526 - May 2008)"

Section and pick the utility that best matches what you need...SATA vs. PATA etc.

Unplug the network cable/disable wifi to take the pc off the network then login using domain admin credentials
If should still have them cached

I have done this several times for the old trust relationship failure

Then reset local admin password

Once you are in to correct trust relationship failure
Reset local admin password
Check time/date are within 5 mins of domain controller
Move pc into temporary workgroup
Reboot
Login again as local admin
Replace cable/wifi
Rejoin domain
Add new domain admin/domain users
Reboot
Should be sorted
