Iwould like to share desktops between my two computers. 1 is upstairs and 1 downstairs. I'm looking to control the desktop, browser, files, etc., of the computer I am not currently using at that time (but it is on). They are both connected to a D-Link router, which is connected to my cable modem. They both have the latest windows updates as well. Here are the specs:


PC1:
OS: Windows Vista Home Premium 32-Bit
CPU: AMD Athlon 64 X2 4400+
RAM: 2.00GB
HDD: 250GB
MOBO: A8N-SLI Premium
Video: ATI Radeon HD 2600XT
Audio: Creative X-Fi Audio Processor

PC2:
OS:Windows XP Pro
CPU: Intel P4 1.8Ghz
RAM 2.00GB
HDD: 80GB and 120GB
Video: ATI HD 3650
Audio: USB SoundBlaster Live External Sound Card


Anyone have any suggestions? Due to the low specs on PC2, I need something that isn't a resource hog. A few programs I have tried were really difficult and slow, but perhaps I'm looking at the wrong kind of program? I've been looking at remote pc software, but a lot of them seem quite resource heavy.
