Have been visiting this forum on a number of occasions but never left a post. Thought I could help you out with your request for a remote support solution so registered.
I was recommended a solution called NTR Support from a colleague who uses it to access SIMS and launch applications remotely. I have registered for a trial version at http://www.ntrsupport.com and it is proving to be a godsend. I have already saved myself a 45 minute journey to a customer site!
Just thought I could be of some help.
Good luck.
