I was having a problem with my network. My computer wouldn't see anything other than my modems, it wouldn't access any networks at my place of business. On top of that my CD/DVD ROM quit working! In device manager it said it was there, but there was some "Registry Issue" that kept it from working. I also had numerous software issues that weren't compatible with Vista, 2 out of 4 printers I use wouldn't initialize, just a whole mess of things. So I posted another thread about it. Someone suggested this link: support.microsoft.com/kb/314060/ and to try "Method 2". It involves deleting registry files, which frankly scared the crap out of me. But I was planning on taking it to a computer repair store this weekend anyway so I figured what the hell I'll give it a shot. AND IT WORKED! LIKE EFFING MAGIC! All my drives were restored, I could see my network, I could use my printers, my previously non-functional software was working again, it was amazing! In my mind I think MS should write this function into the Vista installation process. I'm not saying it will work for everything and everyone, but I had about 6 MAJOR issues that it totally cleared up. So before you junk your system or spend a dime on MS Tech Support, try this first, you might be surprised.
