I'm in the process of creating external one-way trusts to a master domain across several hundred different servers each with their own unique domain.
I've run into a massive problem, however, when deploying the configuration automatically a number of older servers are unable to join 'because file already exists'. Upon further research, it seems my predecessor did not SYSPREP these domain controllers when converting them from a template and therefore can not join the domain without the unique SID. (These servers are all VMs)
My question is, does anyone have experience with obtaining new SIDs for a production server that won't cause the domain controller(s) or SQL to burst into flames or am I SOL?
