Getting "Access Denied" for Windows Updates

Hey there,

I have an SCCM (v2303) environment managing ~600 devices for the last 7+ years with a very high success rate (96% or better). Over the last 3 monthly update cycles, I've had a few devices fail to install an update with this error - "Failed to install update(s) - 0X80070005 - Access denied". All of the devices are on an internal network and have been managed by this SCCM instance for over 3 years. Using Software Center to attempt another installation fails but if I clear the cache and re-run the installation after that it usually succeeds. It's only happening on 3-4 devices each update cycle but it's a bit troublesome. Thoughts?

TIA
