As every one keeps telling you the information is in the startup data base
As for the: rundll32.exe bthprops.cpl,,BluetoothAuthenticationAgent
well thats there also.
It is:bluetoothauthenticationagent & is described as:Associated with BlueTooth software, designed to allow bluetooth mobile devices to authenticate to the computer, when connecting a PDA to your computer - necessary for the computer and the PDA to communicate.
So there you have it...use your brain first and try and work out what it is, read the site info for guidance and then if you get no joy post it in the correct forum and only post once.
As you can see from your original posts you are getting spanked! We all live & learn,but just don't be to lazy to do your homework.
