Active Directory 2003 Native mode vs Mixed Mode

active-directory

My company is switching the Active Directory schema from Mixed Mode to Native Mode.
Did anyone had any problems when doing this?. It is a one way process and I'm wondering if there are any impacts on the way apps will work with AD. (VB6 or .NET apps)

To give you an example of something that I think is under question mark: there is one old app that resolves users from AD using a linked server in SQL. Would this still work?

Appreciated,
Adrian

The only reason to have problems is if you have any old NT4 domain controllers. If they're all gone, going native is advisable.
