While attempting to deploy an Exchange 2007 SP 3 Hub Transport Server, I get the following error message: Hub Transport Role Failed Error: An error occurred. The error code was 2147950612. The message was The requested operation did not satisfy one or more constraints associated with the class of the object.. Any assitance would be greatly appreciated. Thanks. POB7

Sounds like an issue related to Active Directory. Where in the process does it fail? Perhaps you might like to post the contents of the setup log. Neil Hobson | www.msexchange.org/neil_hobson | neilhobson.blogspot.com | twitter @NeilHobson

Neil: The contents of the setup log are quite lengthy. I will have to truncate it in a series of replies. Do you have a better method for me to transfer the contents of the setup log? Thanks, POB7

Hi POB7, Per the information, it seems some issue with schema role on DC server, I would suggest that you could confirm the DC healthy through DCDIAG, and if you have exchange 2007 email ststem already, it is better to confirm the email system work well or not, and then add the HUB server. Could you please post more information about your scenario, then, we could give you more suggestion. Regards!
