I have network analyst installed as an extension in my arcGIS 9.3, but it just does not work!!! when I go to ArcCatalog, the option of new network data set also does not appear... :( I have to do this job of finding routes & I need this to work. I am zero at programming & I don't have arc server as well.

    have you added the extension, you need to go to extensions I think it is under tools in the menu and tick the box, you have to do it seperately in both catalog and arcmap – Banger Mar 5 '13 at 11:13
  • @Sunil: No it is not enabled as yet... – Ade'l Mar 5 '13 at 11:20
  • @banger: I did it the same way as U have mentioned dude... still not enabled. – Ade'l Mar 5 '13 at 11:20

    @user12648 Recommend you to download ArcGIS DT 10.1 60 days trial copy and use it for 60 days.. – Sunil Mar 6 '13 at 7:48

So here is what I would Find out:

  1. Is your License valid, and not expired? To see this go to Start>>ArcGIS>>Desktop Administrator and go to the Availability Section. You will see how many ArcGIS Network Analyst extension licenses are available on your License Server, and how many are free. It will also indicate the expiry date of the License.

  2. In ArcCatalog go to Tools>>Extensions, and see if you have checked out the License for the Network Analyst. This needs to be done before you can use any Network Analyst Tools.

You can watch this link. Network Analyst options will be activated after following certain steps on setting up the problem. http://video.arcgis.com/watch/2109/creating-network-datasets-cost-attributes-and-evaluators
