Exchange Server with NIC on iSCSI network

So I have several machines with 2 NICs, one connets to a corporate LAN, and
the other connects to a iSCSI Network.

I have One DC that also has a NIC on the iSCSI network so it can do DHCP for
the iSCSI devices.

It seems as though from some errors in event logs that some of the servers
and workstations are getting confused with the DC and Exchange servers with
the Dual NICs.

I've set up both NICs to not register in DNS. Though it seems like the
Exchange 2007 server is using the iSCSI NIC to do LDAP queries.

For instance I am getting the below Errors in Exchange 2007. I've done the
dcdiags and other tests and all test out good. Its like its trying to use
the 2nd NIC for other things. How can I make it so that the 2nd iSCSI NIC
is only used for iSCSI Traffic?

Thanks,
Scott<-

The network card on the storage network should not have any of the
usual tickboxes ticked - Client for MS Networks and F&P for MS
Networks etc. Just TCP/IP.

Thank you,

Anything I need to do in Exchange? I changed the Client and Default IPs to
list the internal NIC IP and the NIC used to get DNS Severs.
