Remote Desktop file problem

[apline]

I have an older MacBook with OS X which is used for school, the other day an administrator took over my computer through remote desktop so I immediately took my battery out later i went looking for this Remote Desktop program on my computer and found the following in...
/System/Library/CoreServices/RemoteManagement
In this folder I found what appeared to be a remote desktop file...
Icon: remote desktop icon
Name: ARDAgent
Kind: Application
Size: 2.9 MB
I tried opening this wondering if I could use it to gain access to friends laptops but when I double-clicked nothing occurred
I am wondering if this file can be used as a remote desktop file and how I could open it
Any feedback is appreciated
Thanks

Can you? Probably not. Would we help you if you could? No. You can set them up with screen sharing, though. Leopard has VNC support built in, or you can download a VNC client like JollysFastVNC to connect to their computers after they have set sharing up and given you the password to access their screens.
