Hi Exchange experts,
we are currently have just added a new subnet in our LAN environment. previously we are using VLAN 10 (192.168.10.x/24) for both our servers and clients. Now, we have added one VLAN call VLAN 15 (192.168.15.x/24). the routing has been done between these two VLANs. VLAN 15 is able to ping VLAN 10 servers without any problem. However, VLAN 15 is only not able to ping CAS ARRAY for exchange transport. because of this, the connection from outlook to exchange server is not able to go thru the TCP, only RPC over HTTPS, which is outlook anywhere.
May I know what could be the issue? since VLAN 10 and VLAN 15 routing has been done and both are able to ping to each other, except CAS Array, I don't think there is problem with network routing.
What could be the cause of the issue. I need your kind advise.
Thanks.
Regards,
Henry
