If you are having problems with IE picking up proxy settings etc - then change / compile this AutoIT script so it suits your network:
Code:
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "First Home Page", "REG_SZ", "http://navaho")
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "Start Page", "REG_SZ", "http://navaho")
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyServer", "REG_SZ", "PROXY:PORT")
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "Proxyenable", "REG_DWORD", "1")
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyOverride", "REG_SZ", "intranet")
Run('C:\Program Files\Internet Explorer\iexplore.exe') Use it to launch IE. It will change the reg settings before it launches.
If you have problems running it then use the RunAsSet command at the start and close it at the end:
; Set the RunAs parameters to use local adminstrator account
RunAsSet("Administrator", @Computername, "adminpassword")
Code as above
; Reset user's permissions
RunAsSet()
