I've created an MSI that installs our application. It installs fine if you run it locally on a machine with Windows XP SP2 or SP3. If you run it through SMS to a machine that has Windows XP SP2 it installs fine. But, if you try to run it through SMS to a machine that has Windows XP SP3 it seems to stall and take hours. (It only takes a couple of minutes when run via the other methods.)
Does anyone have any insight as to why it is behaving this way with SMS and XP SP3?
Update
Our SMS guys think they found the problem. We had asked them to do a reboot before the install. They said that on SP3, some services weren't being started before the installer was running. They think this was causing the problem. They're going to try adding a delay after the reboot before the install starts.
