We are currently in the process of upgrading a ICT suite from HDD's to SSD's and the machines that we have upgraded seem to be giving us issues with getting onto the internet for the users.
Whenever a user logs on, they unable to access the internet as it says 'access denied: authentication configuration missing' in Chrome, however when the same user logs off and back on again, the internet seems to work completely fine. It's as if the machines are logging in way too fast and not picking up the right proxy policy for students, hence no internet. We use a proxy server, in which students go out on port 800.
We had escalated this issue with Smoothwall, and they pointed the issue down to settings in group policy after investigation. Not entirely sure if its GP as it would affect every machine on site, but rather only affecting the upgraded machines. Also not sure where to check in GPM?
Apologies if I've created this thread in the wrong place.
Any advice at the moment in time will helpful
Thanks,
Yusuf
