Windows pre-login MAC vs hostname

I'm trying to get pre-login working better so that we can get better computer policy application.  Pre-login is currently hitting a walled garden VLAN because we're only get MAC addresses, and then once in the OS, it auths as user and switches VLANs.  Anyone know in Windows how to get the machine to consistently just send their hostname?

Windows machines will only send their hostname as the username during a
machine authentication.

Okay.... so the only explanation is that my Juniper switch is re-writing it?

Re: Windows pre-login MAC vs hostname

Juniper took verbose logs and analyzed them... they say that their switch is receiving it by MAC and just forwarding that along.  Which means.... the ONLY explaination is that the switch inside our ShoreTel phones is somehow re-writing it.   UGH.......

 

Anyone ever heard of this?

So if you take the phone out of the equation it works properly ?
Thank you

That is exactly my next bit of testing.... just not at work at the moment.  :-)

Re: Windows pre-login MAC vs hostname

where you able to confirm or deny?

It wasn't the phone.  It was Windows 7 being rediculously unpredictable.  It doesn't even seem to care what settings we have.  Even when we can get Windows 7 working... it often breaks TLS because the Skype for Business certificate is issued in the same exact common name and Windows 7 gets confused.

 

We actually gave-up on Windows 7 being smooth with this system and have started a push to get to Windows 10.
