I'm one of the minority that still uses KPF v2.1.5 (desktop and laptop) and yes when I installed the dreaded KB951748 it knocked out IE and Firefox for me. Looking at my logs it was using highports for DNS resolution. I had it specifically set to only use the range of 1024-5000. Made the change to allow highports (1024-65535) and it works fine (desktop only).
Why is changing the local port range going to make DNS more secure? What is the idea behind that?

Try doing a Google or Yahoo! search for DNS spoofing and you will find a lot of answers to your question. Here is a sample link from such a search, I hope some of the results you get will match your technical knowledge level, since I don't know exactly how high or low to shoot.
