:Q - This host has internet access but we're not able to ping/ssh to it. I've reimaged it but issue still persist. Any thoughts?

It looks like during testing ( this machines was very thoroughly used for dev purposes in the past) the permissions were changed on the machine account to explicitly stop the machine from being changed via gpo. I changed the permissions back and checked for other machines in the same state. I am kicking off a re-image now to verify the fix.

Reimage worked fine! Monitor needs to be unplugged and machine rebooted to finish

External monitor unplugged and now I can ssh to the host. Thanks Q! ssh t-w864-ix-001.wintest.releng.scl3.mozilla.com The authenticity of host 't-w864-ix-001.wintest.releng.scl3.mozilla.com (10.26.40.31)' can't be established.
