Here is the problem.  The .27 interface says it is local access only.  I don't know why.  Can you help or give me some ideas what to try?

Additionally complicating matters are a couple of things:

This is a DC, in a domain called XXX.mydomain.com.  I want to be able to just use the mydomain.com also in DNS, and I believe that the XXX naming has messed up my DNS setup, but I don't know how that would effect the network connection saying only local connectivity....

The firewall is turned off completely right now, using advanced firewall control panel, just to make sure that this is not an issue.

I'm worried about IP conflicts, bad cables, anything, but I can't see anyone else using the address and i have replaced the cable into a new switch port in the managed switch.

Please help!

Why not team them?   This will give you failover/load balancing and resolve your issue.

the server is going to pick one nic to go to the internet, the other nic doesn't unless it is directly needed to or the binding order changes. So this is completly normal for it to do this.

Actually I really appreciate both of your responses, and am splitting the points, hope that helps.  I'm curious what best practices are assuming that I don't team, I was assigning different IPs to every NIC, but is it better to create multiple host records with the same server name and the different IPs?

I think teaming will really simplify.  I have already implemented it using the link given by Endure on the windows machines, now I have to do it on the centos/rhel ones.

thanks again

My recommendation is to look at your needs.    If you have some unique situation were you need two separate IPs I would go with that.    In most cases I see teaming being the best because its gives you a bit more fault tolerance.    I have had cables/NICs go bad.
