Isn't that for the server's registry, not the clients... ? If javascript can access environment variables, then you could get the env-var %username% (could have to do with security settings, and could perhaps also be possible through some client-side COM object)
There are tools, like psloggedon.exe (from sysinternals.exe) that can check which users are logged on to a specific IP-name (within workgroup/domain?), and you could perhaps do a check that way (but several people can be logged in at the same time on XP...) "nbtstat.exe -A" does a similar thing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
