Exchange agent cannot get the rootDomainNamingContext property from authenticating DC specified in Exchange agent properties

• Point to a different Domain controller in Exchange agent properties and check if the error persists
• For WMI error when querying Microsoft_LocalDomainInfo, please run the RAD tool on authenticating Domian Controller to verify that all prerequisites are set correctly
• For LDAP error, run attached java tool to test the related LDAP query
• Check the firewall setting in both Domain controller and Exchange server
•                    Rule #1: need local ports 135, 139, 389 (or 636) and 445 opened.
                     Rule #2: need "Dynamic RPC" local ports opened.
                     For more information, see the following article: https://support.quest.com/SolutionDetail.aspx?id=SOL85903.
• After applying above steps, please restart FglAM. As the LDAP command has failed once for environment setting, it will still return NULL for rootDomainNamingContext as Fglam JRE may have cached the results
