OSD Task Sequences failing on Install Software RPC error

[jbudd0649]

We are a small school district in northern VA, every summer we wipe and reload all of our Windows PC's so that the students and staff have a fresh PC at the beginning of the year. Each school has a task sequence unique to their building for software programs. All software is being deployed via the package model during the TS. I recently upgraded our server to CM 2503. We do not use intune nor do we have any type of cloud presence. We have been imaging PC's this way for years. This issue just started after upgrading to version 2503. We are experiencing a high rate of failure deploying the task sequences. When I look at the smsts logs I am getting error 800706ba. The error happens randomly, one PC will fail on Office 2021, and another will fail on adobe reader. There isn't a consistent failure on one specific package. I have tried re-distributing all of my software packages and I have verified that there are no firewalls between the clients and my SCCM server and DP's. We did notice that the Task Sequence fails less frequently on PC's that are directly connected to a core switch. In many of our buildings we have a lack of network drops, so we utilize the ethernet pass through on the back of our cisco phones to provide a connection to the staff PC. If we plug the PC directly into the wall drop instead of the phone our chances of a successful TS completion is much better, but still not perfect. Again, this is a brand new problem after upgrading to 2503. I have attached a snippet of the smsts log. Obviously this could be network related, but since this just started with the latest version of SCCM, I am just trying to rule out any issues that could be caused by the SCCM environment before I go to my network team.
