Hi I made a mistake & instead of remotely connecting to a local PC on the domain
Through the SBS2011 server console, I removed the PC from the domain
Unfortunately the local PC doesn’t have a local password, so I can’t RDC to it
& if I try the user or server AD login, I get a trust error.
Question is how I can put the PC back on to the AD Remotely
It’s an easy Fix on-site or with assistance from there
But would prefer if possible to fix remotely
I’ve tried PStools to add a user password (error access denied)
Windows 7 Pro

Valid local admin credentials are key in administrating that computer. Since you lost it, there's no other way then to get local admin again. Probably you have to guide someone into burning a TRK (Trinity Rescue Kit) boot CD, and get the local admin going again (interactive winpass). After that, get that someone to log in as local admin, and start a remote session (ammyy or teamviewer, preferable installed as a service, so you can get back in after a reboot). Set up VPN again, and add to your domain.

I agree on the fact that this cannot be done without a local account (it would not need to be an administrative account, though). When disjoining from a domain, there must be a local account active, otherwise the computer cannot be disjoined. So there will be a solution if you can logon as some local user.

The guy in fornt of the machine can join the machine providing his own domain credentials in a local account session if you delete the computer account in AD first, without, only domain admins may join, so delete it or, if that poses any problems, give the guy in front of it write permissions on the old object.

If depends on the tools that you're using. RDP is not an option because of a lack of authentication. However, if you're utilizing something like Labtech or VNC, then it would be doable. Or even if you can get someone to get on the computer so you can have them start a remote support session using something like join.me
