I would like to update the schema to windows 2008. I am wondering will that any impact on windows nt 4.0 servers? Thanks, MS786

Will that have any kind of impact on win NT 4.0?

Hello, NT4 and Active directory are different. If you update the AD schema additional attributes are added that have no influcence on NT4 servers. What roles does the NT machine have and which SP is installed on it?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
