Hello I am looking for a way to reinstall dotnet 2.0 at startup without restarting the machine. I have tried the microsoft comand in a bat file wihich works fine if you run it logged on. When is finished it just ask's you if you want to restart, but when i add it to run at startup fom task scheduler it reboots the machine. The machine in question is win2k server, dotnet is not at fault here but the software i am using has a bug in win2k server that if the machine restarts the software security layer in IIS stops working. Also you can see the other prob i have is if it is set to run at startup and repair restarts the machine it's going to do it in a endless loop. Any help in sloving this would be great Thanks in Advance Raspy
