Cannot view .aspx files in IE9 or Firefox on Win7 Pro 64-bit PCs

I have a customer that has five computers on a peer-to-peer network.  All PCs have Windows 7 Professional and using IE9.  All these PCs also use Norton Internet Security.  There is also a Buffalo network storage device to which all PCs are backing up their data files in each their own folder.  All of the PCs have been scanned numerous times for viruses, spyware, and malware.

Recently, this customer cannot view .aspx files on any of these computers using either IE9 or Firefox 6.  They need to be able to view these types of files for purchase materials for their business.  When they access their purchasing web pages from outside their network, they are able to see the .aspx files.  I have researched this on the web numerous times, and have not found any answers.

Any suggestions are greatly appreciated.
Thank you,
Lucy

Just to double-check, have you tried temporarily disabling Norton Internet Security on one machine to see if might be the cause?

Run5k, Sorry, I have to wait until morning to answer that question. Customer is unavailable for the day.

No problem at all, Lucy.  I was just trying to focus upon the common denominator.

This may be silly but are they trying to access those pages thru the web server internally also or just as files?  'aspx' needs the ASP.NET interpreter on the web server to display properly.

Probably just as files from the web pages on which they are trying to purchase various types of glass for the stained glass windows that they make.  The web pages they try to access have the .aspx extension at the end of the web address rather than the .htm or .html.  I sure hope I'm understanding their problem correctly.  They can see the .aspx pages in their entirety from my office, but not their business venue.

They are probably trying to view these files directly i.e. c:\inetpub\default website\buyme.aspx vs http://servername/buyme.aspx

aspx pages require a web server that supports asp or asp.net as the file is not html but will render out html to a web browser

My customer is not trying to view .aspx files on the local c:\ drive.  The inability to view .aspx files occurs when trying to view such files via Internet Explorer e.g. http://shop.edhoy.com/products/WEEKLY%20SPECIALS.aspx  and she want to purchase products for making her stained glass windows.  I just spoke with her and she stated that this started happening after installing some windows and Adobe updates.

Also, my customer has tried disabling Norton and that made no changes.  She still couldn't see the .aspx files on any of her LAN PCs with either Internet Explorer 9 or Firefox 6.  I have not tried to complete any system restores yet however to see if that helps.

I can view that page in Firefox and IE8 from here like you can.  If none of the PCs on her LAN can view that page, then it is likely that something on her network connection is blocking them.  I suppose it is possible that all the computers got the same update at the same time but it would be unusual for an update to cause this same problem on more than one computer.

Note that 'aspx' files get rendered as HTML in the browser.  And it isn't an ActiveX problem because Firefox won't run ActiveX plugins.

We have had a couple of questions where filtering in a router or external firewall blocked pages.  If it is reasonable, you should take a 'known good' computer over there and connect through her network (unless they have done that with their computers and not just another computer).

I am going over to my customer's this afternoon with my laptop and iPad.  She lives 30 miles away out in farm land.  I'll be back here later.

With my iPad, I could not log into http://www.edhoy.com this afternoon as I was now using my customer's internet provider.  I disconnected the router and direct connected to the ISP's modem with one of their desktop PCs.  I still could not stay logged into http://www.edhoy.com/Index.aspx.  It lets me log in initially, and I can see the account information page, but any attempt to view or purchase product and the site returns me to the logon page.  My customer has already called the website's support and they say it isn't their issue, which I understand, because product prices, on-hand quantity and purchases can be completed when logged into the website via any other ISP.

I called my customer's ISP this afternoon and after over an hour of explaining, the service rep decided it was time to elevate the matter to the next level to give them more time to investigate the problem what they can tweak.  They will be calling my customer tomorrow, Thursday afternoon, and check if she can access .aspx pages.

So, I'm not sure what to do, or what I can do here with where I'm at.

I think you've done the right thing.  Something in that chain is blocking those pages and it's probably nothing in your customers systems.

the site is fine here.. it is definitely something at the isp's end. They could be doing man-in-the-middle proxying  the only way is to check the certificate at the customers end.. or they just have lousy bandwidth themselves and https: pages cannot be cached.

It is true, the bandwidth is slow for a dish satellite internet access.  It takes about a minute or more just to load the above .aspx web page.  The ISP blames it on all those kids that are home from their school day using bandwidth.

How do I go about checking the certificate at my customer's end?

being a satellite isp I don't wonder that they didn't suggest a re-alignment of the dish .. My customer and I are both Advanced Amateur Radio Operators and know more about the subject than any of their employees.. I have some NSA level satellite training that probably covers more than what their engineers know.

My customer called me back today to tell me that her ISP never called her, but she tried to access her .aspx webpage and was able to view the price and quantity available.  Woohoo!

Thanks ve3ofa for the validation of this issue originating at the ISP level.
