Disable IE enhanced security in Windows 2008 R2 Terminalserver

One of the IE features in server environments is the enhanced user security setting.
For servers this setting might be ok, but for normal users in a terminalserver it's just not usable.

On the "Server Manager" screen you can specify for users and administrators if the enhanced security should be active or not.
First this is to turn this off for normal users.
If by chance this really has a effect on your users, be happy and enjoy it.

But if you are still reading, then probably disabling this setting for the users did not change anything.

To make it simple:

Login as user and run these 3 commands from the commandline:

Rundll32 iesetup.dll, IEHardenLMSettings

Rundll32 iesetup.dll, IEHardenUser

Rundll32 iesetup.dll, IEHardenAdmin


This bug is only one year old, so please let MS some more time until they provide a fix for it.

Be (a little bit) god under Windows 7

Under Windows 7, just create a folder with the name

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}.


Now navigate to this folder with the windows explorer.
Software developers (even at MS) have some sense of humor :)

Connecting VDSL modem with Cat6 cable

if it's a Zyxel VDSL P-870M, then don't do it

Instead use the supplied ethernet cable (Cat5 UTP)
We did install such a modem and connected it to the firewall system (HP rack server) and did install the PPPoE stuff.
The PPP authentication did work, but then the modem stopped responding on the ethernet port.
We did even switch network port on the server, changed the cable against another cat6 cable, connected a serial terminal to the management port etc.

In a last try we did then plug in the supplied yellow cable.... and it worked.

The supplied yellow cable is a cat5 unshielded cable, with only 4 wires connected.
So probably the modem and server did agree to a gigabit connection when all 8 wires where connected, but then the modem miserably failed as soon as data did flow at gigabit speed.
On a 4-wire cable connection, the server and modem did agree to a 100MBit connection and that's probably the speed the modem is able to handle.
