I had been noticing that my network connections thing in the system tray seemed to be showing constant network traffic to my PC. Recently it had always been looking like this:
Now I was pretty sure that at one time the monitors would not always look “lit up” like that, but sometimes be “dark”, like this:
I was also having network connectivity problems, so I restarted my computer. At that time I got a message saying that DLACTRLW.EXE was not responding. I waited, but it did not close on its own. When I End Tasked it, the network connections monitor stopped showing constant activity.
I did a search to find out what DLACTRLW.EXE is, and decided to remove the DLA key value from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run .
My computer booted up without obvious errors, and now DLACTRLW.EXE is not in the Task Manager’s list of running programs… I think we’re good!
Update 7/24/2008: I also notice that when I’m running an ActiveMQ broker on my PC, the network connections systray icon remains constantly “lit up”.
