We have had the same problems trying to use this at customer sites. We
used it for 'naughty students' to restrict the internet for a period of
time using a 'fake proxy'. However, when we move the students back to
their OU, the students would still be restricted from the internet even
after many reboots over several weeks.


I have all but given up on this as a useful solution to restrict
internet. It acts like a preference and not a policy.  I am very
interested in using this at our customer sites that want a quick way to
temporarily restrict internet access by having a fake proxy apply to the
'naughty OU' and have internet available when the individual is moved
back to their regular OU.


If anyone has a workable solution, please share it.

It's been some time since I had to deal with this, but what you're
describing is exactly what we went through when removing a proxy.

Thanks so far... Well its definately odd becuase if we apply a GPO with
Proxy Settings, the Proxy Settings obviously take place at the client
side. When we remove it the settings stick. The only way I have got the
settings back to normal (i.e. no Proxy Settings applied) is to actually
open the Proxy Setting up, do not configure it at all (yes! just open it
up and leave it all blank) and then save it back to a group policy and
apply it to the OU!!!... the client then takes the new value (which is
blank)... its almost as if you are going to configure it but then change
your mind and do nothing. Its weird, as you'd expect it to be removed
but instead you have to go back and create a blank proxy setting GPO and
apply that.
The only way round so far I have managed is to create 2 GPO's... one
with Proxy Settings and One with No Proxy settings (by this I mean
creating a new GPO and opening the Proxy Settings section and not
filling it out and saving the GPO as that) and then filtering this
against AD security groups.... then populating users who should be
proxied and users who can use the local gateway out to the Internet...
Could it be my environment...I wonder

Hi Taz,


My understanding was that the IE settings just built INS files
(Install.INS, SecZones.inf, Authcode.inf, Programs.inf ) and then ran
them when the policy is applied. There is no process to back up your old
settings and reapply them when the GPO is no longer applied.


Only Non tattooed Admin Templates have true reversal of settings. Group
Policy Preferences support "Delete setting when not applied" which is
slightly different to "Replace original setting"


Darren may be better informed. If so, I would be interested to hear the
mechanism used by IE to back out settings.
