I have a Vista guest running on Ubuntu host. I was trying to fix
the sound problem on the guest by following the instructions
listed elsewhere in this forum ( http://ubuntuforums.org/showthread.php?t=609518 ).

Unfortunately, that didn't work, and it broke my VMWare Tools
and network settings too. I undid the changes I made for trying to make sound work. Here is how things stand now:

VMWare Tools icon shows on the toolbar but clicking on
the icon doesn't bring up VMWare Tools. I reinstalled
VMWare tools but it still shows the same behavior.

Also, now the network doesn't work either. I have network
set to NAT in VMWare settings. The network icon shows:

"Identifying... Access: Local only"

Any help would be much appreciated!
