.net applications run with reduced security over a network. You will need to adjust .Net security for your Trusted Zone with Start-->Control Panel-->Administrative Tools--> Microsoft .Net 1.1 Wizards, Select Adjust .Net Security, Select Make Changes to This Computer, click next, Select Local Intranet, move slider to Full Trust, click Next, click Finish. This will have to be done on each PC on the network, or your Network Admin may be able to do this with Group Policy settings.
