Vista computer can't see other computers, why?

I recently baught a new computer with Vista installed on it, its the first time i've reall used Vista. I have 3 other computers with XP on them. The problem is that the Vista computer can't see the XP computers, and vice versa. They are all on the same network and the XP computers see each other fine. I've tried connecting the Vista computer both through wireless and through a cable, but didn't get a different result. The vista Computer also gets internet just fine, and also detects the router, so it doens't seem to be the router's problem. Anyone have any idea as to what might be wrong?

Which version of Vista? If you got the very basic home version it may not even be supported. You may also want to turn off the UAC.

Try disabling the UAC (User Access Conrtol) by following method #4 here:

I have vista ultimate with UAC disabled and i can talk to my networked XP professional machinie just fine.

Also make sure they are in the same workgroup.

In order for Vista to see WinXP and vice versa, you need to download the Link Layer Topology Discovery (LLTD) Responder for WinXP here http://www.microsoft.com/downloads/detai...

%26gt;%26gt;%26gt;You can also run the WinXP update and look for the file in the Optional or Recommend update section. Simple is that.
