I fixed it by putting this vbscript in startup on the profile (works a treat):
set WSHShell = WScript.CreateObject("WScript.Shell")
' Proxy Settings
WSHShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer", "10.0.0.2:8080"
WSHShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable", 1, "REG_DWORD"
WSHShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyOverride", "10.0.0.*;intranet.*;"
Set WSHShell = WScript.CreateObject("WScript.Shell")
' Home Page URL
StartPage = "http://www.google.co.uk"
WSHShell.RegWrite "HKLM\Software\Microsoft\Internet Explorer\Main\Start Page", StartPage
WSHShell.RegWrite "HKCU\Software\Microsoft\Internet Explorer\Main\Start Page", StartPage
