NHKSrv.exe
(Netropa for Dell)
Netropa Hotkey Server task seen only on DELL and Compaq PCs running Windows NT4/2000/XP. Our understanding is that this task prevents any hotkeys you configured via the Netropa/Dell hotkeys configuration software, from working when your PC is locked by a screensaver.
Recommendation :
NHKSRV is sometimes responsible for literally eating up CPU cycles, up to 90% CPU usage sometimes. So, although NHKSRV is effectively a security feature, you may need to disable it and possibly completely disable hotkey support altogether. To disable, use Starter, or if you cannot see NHKSRV in Starter, go to "Control Panel \ Services" in WinNT4, or "Control Panel \ Administrative Tools \ Services" in Win2000/XP to set this service to "Manual".
