Ixnay. This is bad practice and will cause problems such as you describe.
All servers and workstations should specify *only* the
internal/AD-integrated DNS server's IP address in their network settings.
The internal DNS server should be set up with forwarders to your ISP's DNS
servers for external resolution and/or use root hints. See
http://support.microsoft.com/default.aspx?scid=kb;en-us;300202 for more
info.
