You can accomplish this by using Task Server and sending out a client task to run the script.  If, for example, you're patching process begins at 2am, then schedule the script to run just before that.

Thanks for the reply.  I understand your solution, but would the script have any way to interact with the patch deployment job such as stopping it or delaying it? If not, then there's no point. I need to add logic to the patch deployment process. I need more than just "deploy patches on a given date and time."

What is your aim? I don't really could imagine a scenario for your situation. PatchManagement is for delivering patches to your clients (that's it, not more but not less). If you want customized SoftwareRollout maybe you have to use the SoftwareManagement with great capacity of customizing.

If you want to have conditions according to patches I'm sure there will be ways, but at first please tell us what you want to be realized. Thanks.

For example, if a server that is part of a cluster is slated to be patched on a given night, I need to ensure it is a passive node before patching. If it's not, then I need to move resources off of it.
