Hello all, My dept. using own exchange server 2007. It's one server without cluster as member server on local domain. The exchange sever have 2 nic's, but now, I using only one (the other is disable.) for example with IP :192.168.100.100 (the IP with start 192.168.xxx.xxx is the organization range) The DNS know that IP to send\receive E-mails My Question is : For redundancy, I want to resuscitate the other nic and connect it to other vlan (for example with IP: 192.168.200.100). And to add MX record to DNS. (records to both NIC's IP) At the end, I want - the down time of exchange server will be near to Zero (for network problems...) Is it work well ? Thanks, Zvika

Hi Why not using nic team?Jonas Andersson MCTS: Microsoft Exchange Server 2010, Configuration | MCITP: EMA | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi, Thanks for your comment. Nic team is good for redundancy when you using one IP (or vlan). and when the switch networks is stable . but, what is the better way for unstable switch network ? is what I wrote before , will work well ? Thanks, Zvika
