SYMPTOMS
When you use the Data Execution Prevention (DEP) feature on a Windows XP-based computer or on a Windows Server 2003 based computer, you may experience the following symptoms:  On a Windows XP Service Pack 2 (SP2)-based computer or on a Windows Server 2003-based computer, Event Data Recorder (EDR) opens when you join a Microsoft Office Live Meeting 2005 session or a Microsoft Office Live Meeting 2003 session.

Note EDR captures error report data. DEP prevents the Live Meeting 2005 console or the Live Meeting 2003 console from loading and displaying correctly on a Windows XP SP2-based computer. When you use application sharing on a Windows Server 2003-based computer, DEP may close the Live Meeting 2005 console or the Live Meeting 2003 console without displaying an error message or a warning. You may receive one of the following error messages:

Data Execution Prevention

An error has occurred while creating an error report

Data Execution Protections - Microsoft Windows

To help protect your computer, Windows has closed this program.

Name: Microsoft Office Live Meeting 7

Data Execution Protection helps protect against damage from viruses or other threats. Some programs may not run correctly when it is turned on.

For an updated version of this program, contact the publisher.





CAUSE
These issues may occur on computers that have DEP enabled. By default, DEP is enabled on Windows XP SP2-based computers and on Windows Server 2003-based computers.

DEP is a set of hardware and software technologies that perform additional checks on memory to help prevent malicious code from running on a computer.

DEP can help block a malicious program in which a virus or another type of attack injects a process with additional code and then tries to run the injected code. On a computer that has DEP enabled, execution of the injected code causes an exception. Software-enforced DEP can help block programs that take advantage of exception-handling mechanisms in Windows.
