I rant he best practices analyzer against my file server running 2008 R2 Core server and get this error.

http://technet.microsoft.com/en-us/library/ff633426(WS.10).aspx
All IP addresses for the server should map to the same AD DS site.
Issue:
Not all network adapters are configured with the same Active Directory Domain Services (AD DS) site.

Impact:
DFS Namespaces site awareness will behave incorrectly, with the namespace server potentially providing referrals to client computers at a site that is not local to the server.

Resolution:
Configure all network adapters to use IP addresses from subnets that belong to the same AD DS site.

I am assuming I am getting this error because I have 1 NIC performing iSCSI on the SAN subnet and the other NIC going to corp LAN.  Can I fix this or do I ignore the error?

In Active Directory Sites and Services, expand the Sites container.

Right-click the Subnets container and then click New Subnet.

In the New Object - Subnet dialog box, in the Address box, type the network address or any IP address within the range of IP addresses for the subnet (this would be the range attached to the NIC your having issues with)

In the Mask box, type the subnet mask. (same-for the range your having issues with)

In the Site Name box, click the site to which this subnet is being associated, and then click OK (associated it with the same site as the DC is in your having issues with).

That should fix the issue. You could ignore it safely, but always better to fix the annoying little warnings.
