SCCM - Machines not pulling definition updates from DP

[CHSGM]

Currently have an odd issue where machines assigned to a specific DP are not pulling down the definition updates I have deployed to them.

 

Within the site there are 3 DP's and all have the same content distributed to them, with each school having its own DP to pull content from.

 

At the moment the machines are not pulling down the definition updates I have deployed and I am struggling to identify the reason. I've done some of the basics such are redistributing the content to the DP and I have also queried to machines to make sure to make sure they can see they have updates available to them, which they can.

 

Odd thing is that alongside all the missing AV definition updates (daily), a monthly office rollup was deployed and they all installed that without issue.

 

Attached is a CAS log of one of the clients. Any help would be greatly appreciated

I would double check the boundaries and boundary groups to check if the DP is setup with both of these.

Yep. They completely match up with the same configuration as the other sites and still won't play ball. Even tried removing and re-installing the DP, which has led to no avail.

Figured it out - Appeared to be communication between the DP and Clients. Installed ASP 4.6 and following this it was then working as normal again.
