I can't seem to run ast2 on certain units - an error message consistently pops up - ADTM-113. It sometimes to help when I reset PRam. Does one know what the root of this issue might be?
ast2 error message
Could it be... Satan?
seriously, Apple's engineering teams must have a contract with the devil requiring them to make as buggy and inconsistent a product as possible.
I see the same issue, often. All AST2 resources are up to date on the local diagnostic server, but it doesn't matter.
Like you say, sometimes a PRAM and SMC reset will help.
Last time this was a consistent problem at our shop, apple tech troubleshooting chat couldn't find any way to fix it except telling me to format and set up our whole AST2 server machine again from scratch.
The one from today (because of which searching for the adtm error led me here) refused to run any OS-based diagnostic over ethernet, but it did succeed in going into OS diag mode when run over wifi.

Good morning,
We had the same problem at our location. Turned out to be the switch. We tested with Dell 6224 and Dell 6248 both giving same error. We ended up replacing with a Cisco and the issue is resolved now. Hope this helps!

For someone who still encounters this problem.
Under some network conditions, iMac Pro (2017) models may not start up to diagnostics and instead display 'Unable to run diagnostics. ADTM-113'
If this occurs, try the following steps: Connect the unit under test directly to Ethernet. Using Wi-Fi is not recommended. Use the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter connected to an Apple Thunderbolt to Gigabit Ethernet Adapter. If the issue persists after trying the above steps, escalate to Channel Service Support (CSS). This issue is currently under investigation and this article will be updated as more information becomes available.
