Not sure if it's related, but we've come into a situation once where we moved to new proxies; even though the hostnames remained the same, the IP addresses did change, yet most IE users continued using the old proxies, despite the GPO being correctly configured, and the proxy.pac reflecting this also. It turned out that IE was caching some information; we had to add this vbs (at user/logon) to ensure that the workstations would switch over to other proxies: -- On Error Resume Next Const HKEY_CURRENT_USER = &H80000001 strComputer = "." strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" Set objRegistry = GetObject("winmgmts:\\" & _ strComputer & "\root\default:StdRegProv") DeleteSubkeys HKEY_CURRENT_USER, strKeypath Sub DeleteSubkeys(HKEY_CURRENT_USER, strKeyPath) objRegistry.EnumKey HKEY_CURRENT_USER, strKeyPath, arrSubkeys If IsArray(arrSubkeys) Then For Each strSubkey In arrSubkeys DeleteSubkeys HKEY_CURRENT_USER, strKeyPath & "\" & strSubkey Next End If objRegistry.DeleteKey HKEY_CURRENT_USER, strKeyPath End Sub -- Frank.
