Lmutil - Copyright (c) 1989-2008 Acresso Software Inc. If you're on a 9.3.1 machine, there is a workaround to check availbility, even if the the 9.3.1 client can't talk to the new license server: get a copy of the new 10.x lmutil and run UPDATE: I learned a fix for this will be included in ArcGIS 9.3.1 SP 2 - so Desktop Administrator will 'see' license availablity on a 10.x license server.
I have tested 9.3.1 client on the same machine as a 10.x license server and it works - just like Billy reports - with Desktop Admin's Availability report saying zero licenses available, without any extensions listed. Thanks for sharing your experience - I think this was a firewall issue.
