Local Network is the Public facing network taking the traffic from the users, and the Back network ( is setup for backups and other system administration to happen on).
I have done this type of stuff in the past for those that want to have certain traffic go over 1 NIC ( or set of NIC's) and access for general users over another NIC. Usually don't register the Private ( Back Network NIC's IP) in DNS or WINS accordingly. We would put static entries in DNS accordingly in a special zone which the backup software was to look at for resolution accordingly. That and tight ACL's that only the backup server IP could even talk to that port, and the appropriate firewall rules set on the server to allow the backup software and only that to run. Z Edward E.

You can't really ping a name, only an IP address. If you give ping a name, it looks up an IP address. The first thing to do is to see which IP address ping is lookup up. That will tell you if the difference is in name resolution or some network layer thing. A comment on name resolution that may be applicable: In general, if a name has multiple IP addresses associated with it, you shouldn't depend on those IP addresses being given in any particular order. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
