So Ive got three machines which need exporting, can I do them one at a time? For example, Ive got three servers, 1 x Terminal Server, 1 x SQL Server and 1 x domain controller all running Windows 2008 R2. I can just about export one machine per night due to network speed, power it up and then leave off the old ones.
People used to just say to take it off the domain and then rejoin, but the easier way is to perform the following to re-establish the secured-channel.
netdom resetpwd /Server:DC /UserD:Administrator /PasswordD:mysuperpassword
