Webadmin doesn't inform you if network definition already exists with the same name. Tested on vista sp2 IE8.0.6001
Screenshot: Create a network definition 111 as shown. Now try to create another definition 111 and you will not get an error.
Edit 1: Two errors
1. No popup that definition already exists for the same content/name.
2. If you create the definition with different content (like changing the interface/address etc), still no error and the contents are not changed as long as the name is the same as original.
