Does that lock out the mouse and keyboard when in safe mode then?

Need to find a way of intergrating a script into RM so that either the machine reboots when safemode is detected or it doesn't allow them to log on while in safemode. Have set all the students as domain guests (saves space on the oh so massive 40gig hdds) so there's no local profiles to worry about

I deleted the keys and it made no difference at all on my windows 7 test pc.
Both mouse and keyboard still functioned.

Could someone build such a script, because i am not a scripting guy myself.
Workarounds:Create a login script which logs off the user if it detects the environment variable SafeBoot_Option=Network

Here's an older one I've used on XP before (Haven't tested it on W7 since upgrades)

Haven't tested this at all on any newer systems, but might be worth trying if you got time?
Set WMIService = GetObject("winmgmts:\\.\root\cimv2")
Set Items = WMIService.ExecQuery("Select * from Win32_Environment")
safemode = false
For Each SubItems in Items
if SubItems.Name = "SAFEBOOT_OPTION" and SubItems.VariableValue = "Network" then
safemode = True
if subitems.name = "lib" then
username = subItems.Username
if safemode = True then
msgbox "We caught you " & username
Set OpSysSet = WMIService.ExecQuery("select * from Win32_OperatingSystem where Primary=true")
For each OpSys in OpSysSet

We have Novell setup on the PC's and we've had people try to get in on safe mode with Networking, but they've never gotten any further from the Login box.
Our laptops haven't got Novell installed and the kids have tried to get in on safe mode but we have those locked down with Guest accounts disabled and we have a Universal local Admin password which even if the kids did guess it thy probably wouldn't be able to make out the characters and where the numbers go and since it's about 32 characters long.............. I think we are pretty secure - although we never used to be.

You can log on with any user account in safemode if networking is enabled though, not just guest/admin. And being safemode no boot-services will be running.

Yeah I agree anyone can login with networking enabled - only local Administrator can login to our machines in Safe-Mode with Networking. The only way you can login to the a network account is to login to the local admin account and then login to the Novell Client using the network username - even then on some machines it doesn't authenticate because the Novell services arn't running - but yeah only the local "Administrator" account we have can login. We have had students try to change this Admin password but they can't get into CMD as we have disabled it and we had one person run their own script to do it but nada - because they tried to restart to login to Admin in safe mode but Deepfreeze had kicked in by then and reverted the changes.
We only have 2 local accounts thats Guest and Administrator - Guest is disabled completely, and the Admin account has a really long password

Atm, I am testing LanSchool and I came across this topic, so I wanted to sort this out first before going any further.
And I came up with a whole other approach.
I have copied the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\LanSchoolStudent to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\SafeBoot\Network\LanSchoolStudent
By doing this, LanSchool will also run in Safe Mode with Network enable and the students can still be watched.
I am 99.9% sure this can be done for all other remote tools, like AbControl, Netop, Vnc etc.

Spoke too soon.....
The pupils now tell me they can still press F8 and then choose
"Directory Services Restore Mode"
This boots to safe mode on our win7 test pc's and the keyboard and mouse WORK AGAIN

NoSafeMode does look like a good solution, but there is one small caveat to be aware of.
The unlock password is stored in plain text in the master boot record which means anyone can view and/or modify it with a suitable hex editor.

Pitty you can't get soemthing like those waterproof/washable ones incased in a proper frame so they sit correctly and have the keys moulded together instead of big spaces between them....
