The recommended way of installing the Exchange 2013 Edge Transport server is on a workgroup member (stand-alone server) in the DMZ. However, it is not uncommon that customers are implementing an Active Directory domain in their DMZ for management purposes.
When installing Exchange 2013 Edge Transport server in such an Active Directory domain, the setup application fails with the following error:
“Microsoft.Exchange.Data.Directory.ADOperationException: Active Directory failed on localhost. This error is not retriable. Additional information: the parameter is incorrect.” And “Active Directory response: 00000057: LdapErr: DSID-0C090D8A, comment: Error in attribute conversion operation, data 0, v2580 —> System.DirectoryServices.Protocols.DirectoryOperationException: The requested attribute does not exist.”
This is a known issue with Exchange 2013 which started in CU5. A workaround is to install the Exchange 2013 Edge Transport server on a workgroup member and join this server to the Active Directory domain after installation.
Unfortunately CU6 does not solve this issue and shows the same behavior.
