Which Windows machines are these? 

We just upgraded hg on the iX boxes (and talos-r3-xp) last Friday, so that's a likely culprit. Also, the command line is calling hg directly: is C:\mozilla-build\hg\ in the PATH?

I vnc'ed to t-xp32-ix-002 (In reply to Chris Cooper [:coop] from comment #1)

t-xp32-ix-120 https://tbpl.mozilla.org/php/getParsedLog.php?id=23720223&tree=Ash

I'm pretty sure it is. I tried to vnc into t-xp32-ix-002 and tried running talos_script.py manually. It seems to work fine. It got to the step that where the browser got launched eventually.

This is happening for mozharness on Ash.
Not across the board.

You probably have to define self.config['exes']['hg'] a la
http://hg.mozilla.org/build/mozharness/file/5ef622ddcabe/configs/unittests/win_unittest.py#l18

since it's not in PATH.

Attachment: Added hg's path to exes dict in windows_config.py

Hm, re-looked at the error messages.
Are you actually creating the C:\slave\test\build\talos_repo dir (or is it being created by hg?)  Wondering why the directory doesn't exist.
