We do not normally use Remote Assistance in our workplace however we had an issue this morning with a software developer in Munich who needed to control one of our systems to resolve a problem. He was able to control my machine without a problem however I have now found that most of my systems are unable to use this feature. They get to the point of saving the file or sending the invite and they pop up a message "A program could not start. Please Try again." I have gone through all of the things I can find on the web making sure the Remote services are started, terminal services are running, I set my GPO's up to allow remote assistance, I have tried using my admin account and also regular user accounts. I am at a loss. I got one to work doing all of these fixes and crossing my fingers just right but I cannot reproduce it on a test machine. Most of my systems are running XP SP2 and some have SP3. I really need to make this work and quickly. Anyone else run into this situation? Oh and we dont run the windows firewall and our desktops have no local firewall so that should not be an issue. We do however run McAfee VSE 8.5i on these systems.
