Summary

Windows 2003 Server Service Pack 1 (SP1) includes support for Data Execution Prevention (DEP), a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits. DEP is not compatible with the Mobility XE server on some machines: in these cases, if DEP is enabled the server may continuously reboot or bluescreen immediately after installing the Mobility XE Server software.

This technical note explains how to disable DEP to resolve this conflict.

About Microsoft DEP

In Windows 2003 SP1, DEP is enforced by both the hardware and software and is set to be enabled by default. For more information on DEP, see this document on the Microsoft site: http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2mempr.mspx

Disabling DEP

You should disable DEP before installing Win2003 SP1 on a machine running Mobility XE server, or before installing Mobility on a machine running Win2003 SP1. Follow the instructions below to disable DEP.

If you have already installed Win2003 SP1 and Mobility XE server on the same machine and are experiencing problems (for example, continuous reboots), boot the machine into Safe Mode, then follow the instructions below for disabling DEP. You should not have to uninstall the Mobility server or Win2003 SP1 to correct the problem.

1. Open the System Properties by selecting System in the Control Panel.

2. In the System Properties dialog box, go to the Advanced tab and click the Settings button under Startup and Recovery.

3. Click Edit to modify the Boot.ini file in Notepad.

4. In the [operating systems] section of Boot.ini you'll see a line that looks similar to this:

   multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /noexecute=optin

    

   Replace any /noexecute=[value] DEP boot parameter with just /execute, without the "=" sign or value to the right of it. The line in Boot.ini should now look similar to this:

   multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /execute

5. Reboot the computer.
