Adobe Reader 9/IE 9 blank error message when opening PDF in browser

paulw — Thu, 05 May 2011 09:01:36 +0000

One of our users were having a problem opening PDF documents when clicking on them in Internet Explorer:

This turned out to be a setting in Adobe Reader preferences (Edit –> Preferences) under Internet category. We just simply untagged the “Allow fast web view” and the PDF loaded up in the browser without the error:

This seemed to work OK on the affected client but after reading into this a bit further on the web I noticed that it did not work of all the clients but there was another method that seemed to work as well:

After un-tagging the option for “Display PDF in browser” and clicking on OK the PDF loaded up without any errors but it would launch Adobe Reader and display the PDF file in there rather than in the browser.

IE7 on XP causes “Restore My Active Desktop” error

paulw — Tue, 25 Jan 2011 11:33:41 +0000

This occurred on a Windows XP system running service pack 2 with Internet Explorer 7 installed.

Problem

One of our customers reported that there were a few users that were getting the “Restore My Active Desktop” button appear. When click on it nothing would happen.

Resolution

In this case the fix was to amend a registry setting called DeskHtmlVersion which can be found in the following path:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components

All you need to do is change the value of the DeskHtmlVersion REG_DWORD to read 0

After you have made the change you will need to log off then back on again and your desktop should be restored.

Internet Explorer Stops working randomly when using ISA as proxy on certain websites

Daniel Davies — Fri, 20 Nov 2009 14:52:20 +0000

You may start having issues with certain users who are using ISA 2006 as there web proxy on certain web sites which cause IE not to work until it is restarted.

A possible cause for this is ISA’s Flood Mitigation settings which limit you to 600 http requests per minute. Certain websites will make more request than this limit and ISA will block http requests from the IP address and you will have this error appear in the alerts tab of the ISA.

“The number of HTTP requests per minute from the source IP address *.*.*.* exceeded the configured limit. ISA Server will block new HTTP requests sent from this IP address.”

To stop this issue occurring you can add exception to the flood mitigation settings which will increase the maximum number of http requests to go up to 6000.

To add an Exception to Flood Mitigation Settings

1, Expand configuration and press the general option on ISA management console.

2, Press “Configure Flood Mitigation Settings”

3, Go to the IP Exceptions Tab and add in the computers which are experiencing the issues and apply the rule and you have then increased the HTTP Requests per minute value to 6000.

Hope this helps
