Cause

In this case, the client computers were unable to generate their package snapshots becuase Active Server Pages were not enabled in IIS on the package server.

If Windows Integrated Authentication is not enabled for the Altiris virtual directories, then the clients will not be able to access the ASP pages.

Resolution

To resolve this, we:

1) Checked the snapshot file in the GUID Folder on the Client and found that it was unable to generate a snapshot.

2) We checked the IIS logs on the Package Server, and found that the client was receiving 404 errors when it was attempting to generate its snapshot.

3) We Enabled Active Server Pages in the IIS Manager on the Package Server, and the client was then able to generate its snapshots. This is found in the IIS Manager under 'Web Service Extensions' in the main menu tree.

4) Enable Windows Integrated Authentication if Anonymous Access is only set.
