Hi,
I have used LogMeIn and TeamViewer for remotely accessing my clients' PCs. I like TeamViewer because of its ease of use (client downloads a small exe and runs it, tells me the number and password to connect with and we are up and running) but the licence cost is a bit above my threshold at the moment (US$749 or around there).
What other options are there that are easy to setup and free or little cost?
