Hi Roberta, I don't have a proper answer for you - however I did notice that the Exchange server "Serverold" was causing a problem. Did you Rename the old Exchange 5.5 server before you started the procedure? If so it might be worth checking its AD entry as it could now be incorrect due to the recent change in server name. Of course I could just have the wrong end of the stick :) ________________________________ From: Roberta Campos [mailto:rbcampos@xxxxxxxxxxxx] Sent: 01 April 2004 14:40 To: [ExchangeList] Subject: [exchangelist] Upgrade Exchange 5.5 to Exchange 2003 http://www.MSExchange.org/ I have to migrate from Exchange 5.5 (on NT) to Exchange 2003 (on Win2003). First I used ADC to move the Mailboxes from Windows NT to Windows 2003. When I try Join Exchange 2003 on 5.5, this error occur: "Setup encountered an error while attempting to bind to the Excahnge server "serverold" 0xC103FC93 The account that I'm using has administrator rights on Exchange 5.5. What can I do?
