We have been using Logmein to remotely access pc's. It was originally free.
The first charge was €99 for one years access about 4 years ago. This year they took €350+ for one years access.
Does anyone know of another provider that can give me remote access to our pc's. I've heard of Teamviewer but I believe someone has to be at the connecting pc to allow access.
It's possible to set up unattended access for Teamviewer, so it may be a solution for you. I find it very handy for managing personal machines. However, although you can try it for free, the cheapest business license is similar to the €350 you baulked at. That's for one user initiating one session at a time to unlimited endpoints.
