I don't have access to a Windows DNS server to test this on at the
moment. That being said this does work on BIND.

I don't think this will work with an alias (CNAME) but it will work to
have a different IP per location.

1) Remove your existing SharePoint alias (and let it replicate).
2) Create a new sub-domain that is named the same thing as your
SharePoint alias was. - Do not let this sub-domain replicate.
3) Add an unnamed host (A) record to your new sub-domain using the
IP of the local SharePoint server.

Repeat steps 2 and 3 above on your other DNS server.

Now when clients resolve an A record for what use to be a host record in
the parent domain, they will now resolve an A record for a sub-domain
its self.

If that doesn't work, you can do some other ""interesting things so that
the address that your SharePoint alias resolves to is always local.
