This is a small business with one domain controller and 20 workstations. The domain controller is being backed up by an offsite backup service. System State and Active Directory are being backed up. The offsite backup service says that there are versions of System State and AD prior to the admin password change. The offsite backup service says that the System State and AD can be restored (which has the old password) if customer can connect to the offsite server.
The restore has to be done over the Internet by connecting to the offsite backup service (AES256 encryption) and restoring System State and AD from the backup server. System State and AD can only be restored to its original location while in restore mode.
We rebooted the domain controller into Directory Services restore mode and logged in as a local admiin. Only problem is we cannot connect to the Internet now. DNS and other services are shut down when in Directory Services restore mode (safe mode). All 20 workstations can no longer connect to the Internet.
We tried to restart DNS service to no avail.
While in Directory Services restore mode I looked at the properties of the network adapter and saw that the DNS address had been changed to the loopback address (127.0.0.1). I reset it first to the DNS server address but that did not work since the DNS service was not running. I then changed it to an outside DNS address but that did not work either.
Customer's firewall is managed by ISP and I do not have access to it.
If I could figure out how to connect the Domain Controller to the offsite backup server via the Internet I could restore the old pasword.
I don't know what to do and will greatly appreciate your help.
