IE6 Cannot Open Google / Operation Aborted 1

[CaptainCommandLine]

Using IE6 on Windows XP/SP2 against an ISA proxy and have started encountering the following error intermittently over the past few weeks when attempting to access Google:

Microsoft Internet Explorer
Internet Explorer cannot open the Internet site

http://www.google.com/.

Operation aborted
[OK]

The Google page will briefly flash up behind the error message and then go blank. After I click on "OK", I encounter "The page cannot be displayed". At the very bottom, it states "Cannot find server or DNS Error". If I hit the refresh button enough times, the page will eventually load. Here's what I know:

- If I access the Internet straight out through the firewall and not through the proxy, the error does not occur. When the page loads through the firewall, there are two outbound http connections--one for the html page and one for the Google image. (Switching off "Show Pictures" in the browser eliminates one of the outbound http connections but has no effect on the problem when accessed through the proxy.)
- The ISA server is not caching the Google page.
- I performed a packet capture at the workstation level when the error message occurs and the Google page is being delivered to the workstation. If I copy the html out of the TCP stream and paste it into a text file, I do not encounter the error when loading that file into IE.
- The problem is occurring on multiple workstations; however, does not reproduce inside of Firefox (with computers where both browsers are installed). The problem also does not appear to reproduce on computers running IE7.
- Flushing IE's browser cache didn't make a difference and no other websites seem to be encountering this issue.
- Flushing DNS cache on the workstation didn't make a difference and neither did switching the workstation from using the internal DNS server to OpenDNS.
- If I do an nslookup of "

http://www.google.com"

and http directly to each of the IP addresses, the problem does not occur against any of the specific IPs; however, a different Google page loads, which is branded with the title "Google English".
- A full scan of the workstation using McAfee with the latest DATs doesn't find anything.
- Thought the problem may be related to recently installed KB95838, Cumulative Update for IE; however, uninstalling it had no impact on the problem.

Is anyone else encountering this and, if so, have you found a fix? Changing web browsers is not an option for me and neither is bypassing the proxy. Thanks for taking the time to read my post!

hello there!

have you found any solution to this? i just started having the same problem. bot IE 6 and 7 with ISA 2004 using cache only. eventhough i excluded google from it i'm still having the same problem.

thanks!

I have not found a solution for this, as of yet. For the time being, I've just been tolerating it. We have plans to migrate away from ISA, in the not too distance future, to a different proxy. I'm biding my time to see if it makes a difference. For me, it's been more of a nuisance than anything else. If I do come across a solution prior to the replacement of the proxy, I'll be sure to share. Otherwise, I'm still no closer to a fix than I was at the time of the original post. Thanks!

Have you tried a good ole' fashioned ipconfig /flushdns yet?
Can you get to the site via ip address rather than URL?

My bad, Captain.
Update to SP3. I bet it will fix the problem.

 

[edwinhunt]

installing sp3 did not fix it for me either. so far the only thing that's worked for me is by enabling "use http1.1 thru proxy connections" on IE6. this is enabled by default on IE7 and maybe that's why there's no issues on IE7. at first i thought it was doing it on both versions but apparently just on IE6. like what i've said so far since i enabled it on a few users the problem went away.

Excellent information edwinhunt!!! This appears to have resolved the issue on my workstation, as well! Thank you!
