required Exchange 2000 schema changes not working

[slig]

hi everyone,

i've got a situation where I have a win 2000 domain, with exchange 2000 running on the existing PDC and I want to add a 2003 server to the domain.

according to Knowledge Base article 314649, I have to rename some of the LDAP schemas before adding the 2003 server due to 2000 not complying with RFC 2798.

After much mucking around, i'm at the stage where I have performed the ldifde import and all feedback from the system was that the changes were implemented okay. However, when double-checking in the "schema naming context" using ADSI Edit, the old attributes still appear as they did.

The domain controller i'm trying to apply these changes to is the only DC on the network.

Anybody got some ideas?

thanks
