Raise Domain Functional Level During Business Hours
Raising ad domain functional level.
Raise domain functional level during business hours. All the dcs are now 2008r2. After you set the domain functional level to a certain value in windows server 2008 r2 you cannot roll back or lower the domain functional level with one exception. So i went ahead with both the forest and domain update.
I ve inherited an ad domain that is currently at the 2003 functionality level. Now you raised your domain functional level to windows server 2003 native. Caution this cannot be reversed at any point of time.
If you had windows 2000 dc s that s another story. The most common method to enable the domain and forest. Thanks to all that responded.
I d like to raise. It really surprised how painless and quick it was. After the domain functional level is raised to a higher level it can only be changed back to an older level by using a forest recovery.
When you raise the domain functional level to windows server 2008 r2 and if the forest functional level is windows server 2008 or lower you have the option of rolling the domain functional level back to windows server 2008. After the domain functional level is raised to a higher level it can only be changed back to an older level by using a forest recovery. I was running exchange 2010 on a 2000 functional level.
I checked the ad replication status tool and it found no errors. It s been that way since i started and i never had any problems. Once you raise everything to 2003 functional level those dcs will not be able to talk to nt4 0 dcs.
