Because ArcInfo licenses are limited, remember to change your license from ArcInfo back to ArcView when you finish processing.
To do this in Arc10:
Close any open projects
Click on the Start menu
Select ArcGIS Administrator
Change the License from ArcInfo by clicking on ArcView:
Change the License Manager from " ifwisedn " to " ifwisarc " -- Click OK.
the License server for ArcView is ifwisarc
the License server for ArcInfo is ifwisedn
