Bonjour is terrible. So many people have internet issues with that installed. I immediately remove it on any system I touch regardless, usually using Dameware to uninstall the service.

Here's how to do it from the command prompt. Copy and paste each line into it, then hit enter after each.

del "%PROGRAMFILES%\Bonjour\mDNSResponder.exe -remove"


regsvr32 /u “%PROGRAMFILES%\Bonjour\mdnsNSP.dll”
