DEP / PAE running on server?
Posted on 2010-09-15
I am running a Windows 2003 SP2 server, Enterprise edition. This is a virtual server.
If I go to System Properties, I can see "Physical Address Extension" listed under the memory info.
However, if I look at th boot.ini file, I can't see any PAE switch. The boot.ini is copied below:
WINDOWS="Windows Server 2003, Enterprise" /noexecute=optout /fastdetect
I've read the the optout switch means that DEP is enabled. And if DEP is enabled, PAE is enabled too automatically, we don't need to add an extra /PAE switch to the boot.ini file.
Could someone confirm if this is true?
The reason I ask is because we are in talks with a vendor to install a finance application on our servers, and they advise not to use PAE with their application. Why, I'm not sure.
Could someone advise:
i) What are the actual benefits of DEP
ii) Can we leave DEP running but disable PAE
iii) Is it recommended to have DEP with PAE disabled
Any help appreciated.
