error massage

hi all
the latest silly thing is the attached error massage, every time i close a program it pop up and force me to log off and re log in, is there ant way i can shut this thing??
thanks in advance

One of the first things I do on an XP install is disable DEP. Has caused no problems on any of my machines doing this.

Be sure you have 'show hidden files and folders' enabled. Open 'My computer'>C:\ . Find the 'boot ini' folder,right click and choose 'open with notepad'. Find the portion of a sentence that says: /noexecute=optin and remove it. Replace it with: /NoExecute=AlwaysOff : Go to the file menu in notepad and click 'save'. Exit file menu and then go back to it and choose 'exit'. Reboot and DEP is dead.

hi, thanks....i am trying to located this boot ini..... i can not find it although i had exposed all hidden files, any more info on where to find it??

well i have located the boot.ini file, i removed the /noexecute=optin and replaced it with /NoExecute=AlwaysOff , when i try to save it refuse to save and tell me can not save..... so how??

the file looks like this;

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

i am removing only the red color words

In your case you would want to add Windows Explorer to the list.
And a description of DEP, though it may be overkill

Could be you weren't logged in as admin on the first go-round. But yes, your second method would have been my next recommendation.
Glad you got it done...:)

Further to my problem above, I had managed to shutdown the DEP but I am still getting error message that window explorer need to close and I have to go to task manager in order to close Dr. Watson to get my laptop out of its freezing condition.
any advice?
