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 
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.
