we are pushing down proxy settings through a login script. they get set and everything works fine. after 90 minutes gpupdate runs and the proxy settings are blanked out. We have verified that its defently get blanked out when gpupdate runs. their are no group policys setting proxy settings on the ou or domain level or anywhere else. the ou’s with no group policy are not effected. We did have one but it was deleted and replicated to all domain controlers. does anyone have any idea how to fix this or why this is happening.
