I have two XP SP3 test machines that are running SMA 7.5 (7.53.x). Both machines receive patches via Managed Software Delivery policies. These policies have pre-detection checks. The policies are delivered to the machines, the pre-detection check runs, and the pre-detection check fails with error code 2. This error code is supposed to indicate that the patch wasn't detected and needs to be installed. However, the status of the pre-detection check never changes to "Compliant" or "Not-Compliant", it remains "In Progress". The pre-detection check run repeatedly and then fails with error code 2. Therefore, the patches never download and install.
I've removed and reinstalled the agent on both machines several times. The machines have been reverted to snapshots more than I can count. However, the problem persists. I borrowed another test machine, pointed it to the same servers/infrastructure, and the same patches installed just fine. Any ideas on how to troubleshoot/resolve this? Thanks.
