Below is the status message of the advertisement of my Deployment of Windows 7 via SCCM.
The can confirm that the current time on the client is between the advertisement start and expiration time. The client doesn't appear to download and run the task sequence.
Advertisement "WIN20027" was received from site "WIN".
The client passes any supported platform requirements and the SMS will add the advertisement's program to the list that will be displayed to users and/or run via assignment. If an advertisement is received but not displayed on a client, verify that the current time on the client is between the advertisement start and expiration times, and that the program specified in the advertisement is enabled.
Any ideas, so close yet so far......
