i had to change my ip address scheme from 192.168.1.X to 172.16.26.X and there are some old Unix boxes that used to use a 192.168.1.X address to get their license info. these Unix boxes are so old, i can't find where the conf files are for their license info. I thought it might be easier if i made a dns alias on what the Unix boxes use for their name server, then they would be able to find the server through the alias. At least that is my theory. the Unix boxes use my win2003 domain controller ( as the name server. this domain controller happened to be the Unix box license server which was address so if i go into the DNS of my win2003 server and make an alias from to, maybe the Unix boxes will find the license info. I'm just not sure how to set up an alias, or if this theory is even in the ballpark.

    Accepted Solution

    Is there another interface on the Unix box and the Win2003 server? You can setup the original IP on the second interfaces on each machine which should allow you to use whatever licensing info you need.

    no, there is just one interface. i haven't changed the old Unix boxes to the new ip scheme. however, 192.168.1.X can talk to 172.16.26.X through my router. so on my win2003 server i can ping the Unix box just as my Unix box can ping my win2003 server. i have a second interface on my win2003 server, but i have run into problems when i had both interfaces enabled in the past, so i would like to avoid that. unless i ran into problems do to my lack of understanding of running two nic's on a win2003 server.

    I'm really not sure what service of function we are dealing with. Are you sure this licensing stuff isn't pulled using a non-routable protocol like WINS or UDP or something? More information would be helpful.

    I ended up biting the bullet and changing the IP's on the Unix CAD boxes, and it went fine. Thanks for the input.
