Hi, Have you configured the reverse lookup zone from DNS for both the subnets? Post the below output dsquery subnet -name 10.1.132.21/24 | dsget subnet dsquery subnet -name 10.1.5.0/24 | dsget subnetBest regards Biswajit Biswas Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
