Multiple NICs, Multiple subnets, Exchange Server Active Sync
Posted on 2009-05-01
I have an exchange 2003 server that has been operational for years and allows synchronization of email through PDAs (e.g. iPhone). This has all worked marvelously until I added a second NIC on a separate subnet for the server. We added a SAN device and I'm separating the ISCSI traffic for the SAN on the second card on its own subnet. Both nics go to th same switch that has been segregated into VLANs.
The new card breaks only the Active Sync part of the exchange server. Everthying else with email traffic works fine (sending, receiving, OWA, etc.)
I am thoroughly perplexed!
