The problem is best described by the Ask Jeeves page I found while searching for the answer:
I read their solution, which came directly from a Microsoft support page addressing the problem. Should fix the problem, no? Well, not quite
First off, besides being paranoid about fiddling with my registry settings, I don’t quite understand what they want me to do. I’ve looked all about the MS support site, but can’t find any explanation of their instruction’s conventions. The give me two suggestions for registry entries to create:
Well, the comment (Sets the number…) is not part of the entry (I don’t think), but what about (Default X)? Is this supposed to be typed in exactly as it is in the line? Do I change the number to the number of simultaneous connections I want? Do I leave the word ‘Default’ in? What will happen as I put in higher and higher numbers? More downloads will cost me in bandwidth per download, but will it cause my system to become unstable? I also have Netscape on this machine, and it happily downloads several files at once, but I can’t find a corresponding registry entry. Also, do I put in both lines or just one? How do I tell which I should use?
Lastly, here is a rather ominous bit :
What does that mean? Am I going to cause a server somewhere to crash? Am I creating a security problem for myself? Why should I avoid standard browsing? Will I soon hear the ‘jack-booted thugs kicking in my door’?
