We just experienced an issue where all of our workstations ran an application deployment even though there wasn't a required deployment to them. We called Microsoft and they told us that we'd need a Premier account to get root cause analysis.
Here's the details:
-Application 2 is in our task sequence that is being advertised to All Systems as available (thru PXE and Boot Media only)
-Application 2 has a deployment type which includes a Supersedence rule to uninstall Application 1
-Application 2 has 2 deployments. A required deployment to a small computer collection of 5 workstations. An available deployment to a small user collection of 5 users.
NOTHING ELSE.. but for some reason all systems ran the deployment type for App2 (which uninstalled App1 - but failed to install App 2). What on earth would have caused this to happen? I'm not concerned that the install failed, I'm just concerned that it ran the uninstall of App 1 without a required deployment.
Any help would be MUCH appreciated.
