IIS: How to disable Data Execution Prevention in W

问题:

I've been trying to disable DEP on my windows 2008 dev box and have not succeeded.

I've tried: System Properties->Performance Options->Data Execution Prevention->Turn on DEP for essential Windows programs and services only

(still happens)

System Properties->Performance Options->Data Execution Prevention->Turn on DEP for all programs and services except those I select

in this case, i tried to choose both inetinfo.exe and w3wp.exe in the c:\windows\system32\inetsrv\ folder, and when selected, I receive this error:

"You can not set DEP attributes on 64-bit executables".

I'm sure that there is some memory leak somewhere - but that is a separate problem. I'm happy to live with it for a while in my development environment (in fact that is where I need to let it go so I can see it)

Any help would be appreciated!

Thx, Doug

The GUI does not show the 4 modes of DEP operation.

You need to do it at boot time:Boot Parameters to Configure DEP and PAE

However, more info on the error message:

System DEP configuration settings apply only for 32-bit applications and processes when running on 32-bit or 64-bit versions of Windows. On 64-bit versions of Windows, if hardware-enforced DEP is available it is always applied to 64-bit processes and kernel memory spaces and there are no system configuration settings to disable it.

Here is how to disable DEP at the command prompt:

BCDEDIT /set {current} nx AlwaysOff

回答3:

On Windows Vista and later, DEP and PAE are enabled at boot time and are configured by setting values for the nx and pae parameters using the BCDEdit /set command.

To disable DEP on Windows Server 2008 type the following on an elevated Command Line

bcdedit /set nx AlwaysOff

you would want to edit boot.ini and change a section contaning /noexecute=optin to just /execute

回答5:

You should be able to turn DEP off in one of your BIOS settings.
