You should try to avoid using the WinNT: provider for ADSI - it's old, it's only there for backward compatibility, and it's severely limited in its capabilities.

Is this a user account in a network environment? If so, use the LDAP:// provider instead - it's much more powerful and more flexible in many ways.

Where exactly is your code failling? It's not clear from your post. On the .Invoke() or on the .CommitChanges() call?
