I have Remote Desktop successfully working behind the router. However, I cannot access the desktop when outside the office. If I leave my laptop (also Windows XP Pro) at the office and use a third machine, I can reach the laptop, but not the desktop. All PCs are running XP Pro SP3 and the firewall is OFF. I have even forwarded port 3389 to the desktop with no success. I have DSL with AT&T/Bellsouth using their Westel modem, a Linksys router and a Linksys switch off the router. In fact, the laptop and Desktop are attached to the same switch. Thanks for your help. Kg4ibj
