Hi, I have a problem with one of my GPO on the domain it is attached to OU that have users and is configured to set proxy parameters. I change a proxy address two days ago and when you restart the pc new settings will apply but after couple of hours user will get old proxy settings back. I added two DCGC 2008 to domain recently but I do not see problems with any other GPOs except this one. If I open proxy GPO and under the setting i see new settings and there is no other GPO that deliver proxy setting except this one.
I also check the AD replication and it works with no problem.
