Install Exchange 2007 in Windows 2008 SP2 in a Windows 2003
Is there a way to retrieve a program I previously have on my computer prior to another program installation? I tried to install Exchange 2007 in Windows 2008 SP2 in a Windows 2003 environment where I change the 2003 SPs installed on the sole DC.
However when I tried to run “Prepare Schema” and “Prepare AD,” I received an error prompt appeared on my screen.
It said, “Extending Active Directory Schema in progress…… FAILED Active Directory operation failed on mail.mydomain.com.jo. This error is not retrievable. Additional information: The parameter is incorrect. Active directory response: 00000057: LdapErr: DSID-0C090A85, comment:
Error in attribute conversion operation, data 0, vece.”
