I wanted to share something that I observed recently on my own PC. I am running Vista Home Premium, it came on my Alienware box. I had some directories shared so I could hit them from some of my other PC’s, and the share names had underscores (_) in them. Well, I recently installed Vista’s SP1 and afterwards, I noticed that my network shares were not working. Hmm, that’s strange. Skip ahead and what I found out was that after the SP1 install, my share names were renamed to the same thing, only without the underscore. Well now, how about that? So I had something like share_name, and then it became sharename without me changing it. Not that big of a deal, but I thought I would share just in case anyone else was having the same troubles.
