Hi Guys, I have 9 Parent Child Domains (W2k & W2k3) running in 2000 Native mode. My exchange server is sitting in parent root domain only. RUS had connections with all child domains. I had an old exchange 2000 server. We followed swing method to move the mailboxes onto the newly created exchange server. I managed to change all the required components except for one. I'm not able to change RUS connection pointer to the new exchange server on 5 child domains. Rest I managed to change successfully. When I try to change the entry I give me an error message that you do not have required permissions... Run /domainprep on the respective domain. I have run /domainprep on child domains but still the situation is same. Anyone has any idea about it? Await your reply. Regards, Rajnish
