Not receiving password reset emails or new trusted device emails

Personal Usage.. one of my 4 PC's clearly is running TV, but is being shown as offline at mgmt console (and I can't get to it in unattended mode).  I tried to run it thru unattended SETUP again, but the "trust email" is not being generated.  I've seen similar issues in the past where TV gets hung up, restarting the PC usually fixed that.  But I have restarted the target PC several times to no avail.  I can access it directly via its ID & password  but not in UNATTENDED mode.  This unit has no keyboard or monitor so TV is the only normal access.  if this keeps up, going to have to start looking for an alternative.  I have also had problems before where TRUST EMAIL verification fails to be sent
