I thought the ACC might have been my problem a couple of days ago so I went ahead and set one up
Before this though ACC was set to use the application credentials with "Run from server if bandwidth is above" still set and I didn't experience any problems.
This is the Run History from a computer that has had consistent failures since Monday when I started seeing this.
Something I've been noticing is that the Source of the install changes from computer to computer; for example the first two attempts that ran on 11/2/2015 were the actual path of the MSI, and then it switched to using a shared location.
This is Run History from a laptop.
The targeted agent settings for our laptops do not have the "Run from the server if bandwidth is above" option checked off, yet it seems like this one was trying to do just that.
You can see in the second Run History image that the agent attempted to install from the shared location, and then switched to running the install from a local location. Running from the local location caused the run to complete successfully.
Any thoughts?
