Can only access https: not http

Well as your info is so sparse I will guess you using IE? Have your tried a different browser e.g. firefox? You could try to reset browser to default settings wherever there located in IE options.
 
Please accept my apology, techmanc. I didn't realize I'd actually posted this. I thought I was simply searching the forum.

As far as info is concerned, I have done the following things:

1. Reset ALL default setting for IE6
2. Upgraded to IE7
3. Performed simple routine maintenance on pc
4. Re-registered all .dll files associated with IE.
5. Verified proxy settings and trusted site settings.
6. Yet to do is verify Registry settings according MS website.

I did not think about using a different browser all together, although that is a good alternative. But IE is a company standard where I work. Using a different solution is not really the mark of a problem solver, IMHO (no offense to you) as I'd like to help my teammates figure this one out. Anything else you have would be great.
 
Again, my apologies. I meant no harm. If you can help, that would be great. I will continue to research elsewhere if no else can help on this post.
