Is rhe account you are using in "Entrerprise Admins" ?Karl

Hi Nitin,You can check to see if you are logged on as a member of Enterprise Admins as well as the schema admins. In addition to this you can make sure that the Schema Master server role can be contacted or at least queried from the exchange server. What do you get after running netdom query fsmo from your exchange server? You can also refer the exchange server setup logs for detailed information.http://technet.microsoft.com/en-us/library/aa996158.aspxhttp://technet.microsoft.com/en-us/library/aa995868.aspxMilind Naphade | MCTS:M | http://www.msexchangegeek.com

That is correct. Didnt you know that Exchange 2007 SP2 modifies the schema before it gets installed? Glad to hear that you know it now. :-)Milind Naphade | MCTS:M | http://www.msexchangegeek.com
