I am working to get multiple AutoIt scripts to run invisibly for the workstation user. Unfortunately, as soon as Switch Users is enabled the AutoIt script pauses. The best solution for this is to have Terminal Services open on a separate computer (on a non-visible desktop using Dexpot). But, for some reason as Terminal Services windows are minimized, they also stop running the AutoIt scripts (or, rather, they stop finding windows to work with).
I had great success with Terminal Server Patch v1.4 on my own workstation but it didn’t work on a newer Dell, so further research led me to the following sites to try. Hopefully, I’ll come back and edit the results of my experiments. The other option I have is to purchase for $150 a solution from AikoTech IT Solutions that will give one workstation 3 concurrent connections (3 users pack for LOW PRICE of USD 150 per server).
[On Edit] The first link below outlined the steps to take that solved my problem.
[On Edit] Also, I was not able to find the terminal services policy in Group Policy Editor (start/run/gpedit.msc) but it turned out to be easy to restore once I found the right question to ask Google. Thanks to Ramesh Srinivasan at Winhelponline.com for Restore Missing Folders to the Group Policy Editor in Windows XP. Basically, highlight a primary category, go to add/remove templates, then select system.adm.
Links rated as of this date as having the most potential of accomplishing the task on XP Pro SP3.
