When I add a second network adapter to Exch 5.5 SP4 (NT4 SRV SP6) MTA doesn't start up with error 2140. I have made bindings for "all protocols" as follows:
1st Card is on the first line and 2nd card is on the second line. Also WINS is disabled forsecond adapter.
When I remove the 2nd network adapter everything is fine.
Do you have any extra suggestions?
1. Net. Card (LAN):
IP-10.54.54.101
SM-255.255.252.0
GW-10.54.54.4
WINS-10.54.54.100
DNS-DNS of ISP

2. Net. Card (SAN):
IP-10.54.60.10
SM-255.255.252.0
GW-No
WINS-No

Both of Network adapters are Gigabit Ethernet 1000.

I have noticed some weird behavior with exchange having 2 nics.

I have been unable to find any reference that says you can't have 2 nics.

But my question to you is, why have 2 nics installed that are on the same subnet?

I can see exchange getting confused on that one.

What other error messages are in the event viewer.
