LV6.1 does have built in functions for remote control or remote viewing (faster) through an Internet browser or another PC running LV. I don't think you need to know much about TCP/IP either. The web publishing tool does all the work. Select the menu "Tools" -> "Web Publishing Tool" and click Help to get started.
Also search the online knowledge base: http://zone.ni.com/devzone/conceptd.nsf/webmain/e789515b9976253786256b1f007e039b?OpenDocument http://digital.ni.com/public.nsf/websearch/09B82EFACFF958A586256BC800779CB4?opendocument The first step would be to get the remote control working the way you want it from inside your firewall (i.e., run your equipment from your office PC). Getting it to run from outside the firewall will be more difficult and may require access by your IS department. Hopefully, someone who has done this can help you out.
