I am having trouble getting new proxy settings to apply on some computers in our organisation. I am not sure exactly how proxy settings have been applied in the past, but for some reason, the old settings are not being replaced. The policy is attempting to use internet explorer maintenance settings to set the new proxy. I have tried the setting in group policy Process even if the Group Policy objects have not changed but this has not helped. Looking at brndlog.txt, on affected clients I am getting the error ! Processing of this Wininet.dll connection settings failed. I have googled that without much success. I have run gpupdate /force & restarted. RSOP.msc does not show any errors and as far as it is concerned the proxy is applying OK. If any one can give a pointer, I would be grateful. My only fix so far is to move the user from the particular OU with the policy, move it to a unrestricted OU alter the settings manually and then put the user back again - this has worked on 3 + occasions.
