Does the ASP page expect the parameters passed to it by POST (rather than GET as you are trying)?

Try (based on the HTTP::Request::Common docs): 

use HTTP::Request::Common;
my $ua = LWP::UserAgent->new;
my $res = $ua->request(POST 'http://100.100.100.100/ReceivingPage.asp'
+, [username => 'test', password => 'test']);
