Random users don't have Net access through Censornet

[markman]

I have a weird thing going on here!!
Random users don't have Net access through Censornet, the log in window just doesn't appear and the browser doesn't pick up settings. It is completely random through all 5 school year groups?? It is picking user up via AD and most users are fine.
Any ideas would be greatly appreciated, I did post on the Censornet site but the forum has been down a while. I am probably missing something obvious though!! ops:

1) When you say random users, do you mean the same users every time but no apparent connection between them, or the problem randomly occurs for all users?

2) 'Picking up browser settings' - shouldn't be a Censornet issue, should be group policy? If the browser settings aren't picked up properly, obviously the user won't get the login prompt as their machine won't try to contact the CN box... See if you can nail down if there are issues with those users profiles?

Is it definately user specific not machine specific? I don't know much about Censornet in practice (see my other thread) but I am aware that you need to register the MAC address of each station allowed to use the 'net. Could this be the issue.

It is down to the same users, wherever they log on they don't get the log in screen and the default home page is the schools site but for these users in tries to go off to the default Microsoft site and all our users are set up the same way.

You can use MAC address or IP address, we use IP.

Cheers for the help

Not sure if Censornet is at fault here. Can you check the GPOs are applying ok for the user? In particular the IE branding and the proxy settings?

Geoff is right there, the behaviour you are seeing is because of one of 3 reasons.

1) Connection has been disabled for that machine in CN.
2) The Machine is Not registered with CN.
3) The proxy settings have not been applied.

It does point to no 3.

I use this in my logon script when I have trouble just to do a quick check.

Set objWMIService = GetObject("winmgmts:\\" & strComputerName _
 & "\root\cimv2\Applications\MicrosoftIE")
Set colIESettings = objWMIService.ExecQuery _
   ("Select * from MicrosoftIE_LANSettings")
For Each strIESetting in colIESettings
   Wscript.Echo "Proxy: " & strIESetting.Proxy & VbCrLf & "Proxy override: " & strIESetting.ProxyOverride _
   & VbCrLf & "Proxy server: " & strIESetting.ProxyServer
Next

All the PC's are set up and enabled for CN and allow other users onto the Net. I agree that it looks like the proxy settings not being applied, anyone any idea why it is happening? and so randomly?

The script you attached, excuse my numbness but how do you run this? Beyond batch files I am a bit lost.

Save it as whateveryouwant.vbs it a vbscript.

Get that popping up to see if the setting is applying easy and if not you need to review how the settings are applied.
It could be DNS, NIC problems or something that can be fixed by simply reimaging/RISing the machine and GPs will work correctly.
Run netdiag and use the group policy management console to do modelling and GPresults.
