Dev disp +work.exe getting disconnect

Hi Expert,

I having the problem, that is every 3-5 min disp+work process getting disconnecting and i.e. getting automatic connect also.

Actually what i have done means one day i was restarted the dev. system after that i received a msg like "Winnt blocking the program disp+work.exe for that you need to change setting" and it shows 2 cmd button like change setting and close this msg, when loaded the desktop screen. I have selected change setting, there was 3 check option, last check box was selected default and i have selected first check option of SAP. From this change only i'm facing problem.

Now how can I change like default setting. Pls give solution.
