Windows XP displays by default shares from other computers the following way:

share_name on comment_text (computer_name)

It is possible to change the position of computer_name, so it is shown next to share_name:

share_name on computer_name (comment_text)

This is done with this registry key:

[HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Explorer]
ToggleCommentPosition = 1 (0 = Default)
