Internet Explorer Secuity Warning: Do you want to view only the webpage content that was delivered securely?

April 21st, 2011. Published under Uncategorized. No Comments.

I came across a computer with Internet Explorer 8 that was showing this warning every time he browsed to a new page within a few banking websites. I added the URL to the Trusted Sites zone, but this did not do the trick. I then enabled “Display mixed content” for the Trusted Zone, which should have done the trick (Internet Options -> Security tab -> Custom Level button.

However, this did NOT do the trick. The issue is that the website, which is secured with HTTPS, is trying to load some content that is NOT secure (via HTTP). This causes IE to throw the warning. The “Display mixed content” tells IE to ignore this issue. The reason this did not fix the issue in this case is because I enabled “Display mixed content” in the Trusted Sites zone, but the HTTP data was being loaded from another domain which was NOT in my Trusted Sites zone. I enabled “Display mixed content” for the Internet Zone as well and the warnings ceased.

I know what you are thinking. Isn’t this now less secure? The answer is “probably”, but in my opinion, this isn’t a big deal. Maybe I am wrong and this can trick you into having malicious code run, I’m not sure. Honestly, I think if any site loads HTTP data within and HTTPS session, its bad coding to begin with.

Anyway, there are a lot of posts for this fix out there, but many of them say the “Display mixed content” fix didn’t fix the issue for them at all. Maybe doing this for all zones will fix the issue for them.

Recycle Bin is corrupted on Windows XP

March 16th, 2011. Published under Uncategorized. No Comments.


I fixed this today using a bit of info I found on here. Google-fu will turn up a lot of different suggestions. Even the Kelly’s Korner registry file failed to work for this one. Once we did see the “The Recycle Bin on c:\ is corrupted. Do you want to empty the Recycle Bin for this drive?” error.

Basically, you make sure you have “Hide protected operating system files (Recommended)” UN-checked in Explorer, which you find by clicking Tools -> Folder Options -> View tab from an Explorer window. Then you’ll be able to see the hidden “RECYCLER” folder on the root of each drive.

If you rename the RECYCLER folder on the drive that has a corrupted Recycle Bin, then delete something on that same drive, Windows will create a new RECYCLER folder and the problem will be resolved.

I suggest re-checking “Hide protected operating system files” in Explorer when you are done.

My Computer does not show CD or DVD drive in Windows XP

October 14th, 2010. Published under Uncategorized. No Comments.

I have seen this a few times in recent months, so it is worth documenting. The CD or DVD drive does not show up in My Computer, and in the Device Manager it is showing a warning (yellow circle with black exclamation point in it). The description of the warning states something about the drivers being installed but the device is not present, when the device is most certainly present.

The fix is a registry hack. Be sure to export this key before making deletions, in case things go awry. The key to navigate to is:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Delete the following values in the right pane.  Note that both values may not exist.

  • UpperFilters
  • LowerFilters

Restart the computer and your drive letter should return.

Add-ons list in Firefox is empty / blank

March 4th, 2010. Published under Uncategorized. No Comments.

In Firefox 3.6, I was suddenly unable to install or edit any of my add-ons. The list of add-ons was blank, and it would not let me install any new or update any existing add-ons. The add-ons themselves worked just fine in Firefox.

After doing some searching, I found the issue had to do with the use of Personas.  This issue also can occur in Firefox 3.5.x.  The following solution (found here) fixed the issue for me:

  1. Enter about:config (type “about:config” in the address bar of a new tab)
  2. Filter for “lightweightThemes”
  3. Erase the value for lightweightThemes.usedThemes
  4. Change the value to “false” for lightweightThemes.isThemeSelected
  5. Close and restart Firefox

Doing this of course removed the Persona I had loaded, but it solved the issue.

CD / DVD drive missing / not recognized by Windows

March 3rd, 2010. Published under Uncategorized. No Comments.

Recently an associate came across this issue, where a Windows XP laptop was not showing a drive letter for the DVD drive. The drive was obviously powered since it would open when the eject button was pressed. In Device Manager, the drive was showing the yellow exclamation point symbol for a device that had a driver issue. The usual action of deleting the device in Device Manager and restarting did not change this; it just came back with the yellow exclamation mark.

Googling for this issue let to several forum posts where the solution was a quick deletion of two values in the registry. The solution, which works for Windows 2000, Windows XP, Windows Vista, and Windows 7, can be found at the Microsoft Support site.

A quick reboot after the registry deletions fixed the issue on this laptop.

DHCP database and Jet errors caused by AVG 9

December 3rd, 2009. Published under Uncategorized. No Comments.

Suddenly my Windows Server 2003 AD controller was throwing errors about the DHCP Server service running on it and the Jet database.  The Event IDs were 485, 215, 1014, 1016, and 1010.  Here are the specific errors logged:

* Event Time: 23 Nov 2009 01:31:41 AM
* Source: ESENT
* Event Log: Application
* Type: Error Event
* Event ID: 485
* tcpsvcs (3800) An attempt to delete the file “C:\WINDOWS\System32\dhcp\j500322E.log” failed with system error 5 (0x00000005): “Access is denied. “.  The delete file operation will fail with error -1032 (0xfffffbf8).

The following problem occurred with the Jet database -1032:

Jet database read or write operations failed. If the computer
or database has just been upgraded, then this message can be
safely ignored. If this message appears frequently, either there
is not enough disk space to complete the operation or the database
or backup database may be corrupt.  To correct this problem,
either free additional space on your hard disk or restore the
database. After you restore the database, ensure that conflict
detection is enabled in DHCP server properties. For information
about restoring the database, see Help and Support Center.

These were driving me nuts.   I tried a few things like copying over the DHCP configuration files from my other AD controller (which was configured with DHCP Server but disabled for backup purposes), but nothing I did worked.

Then I realized the day before these errors began I upgraded the AVG client software from AVG Antivirus Network Edition 8.5 to AVG Antivirus Business Edition 9.0.  So I Googled about these errors and threw “AVG” into the search and found this forum thread, which supported my theory of the AVG upgrade being the culprit.

I then contacted AVG Technical Support about the issue, and the response I received instructed me to “remove the AVG Service for optimizing scans”.  The specific instruction was to run command line switches on the installation package.  So using a recent installation package, I typed the following from a command line:

avg_ipw_stf_all_90_707a1765.exe /REMOVE_FEATURE
fea_AVG_NtfsChangeJournalCach

A wizard dialog will appear where I selected (per instruction) “Add or remove components”, and just clicked “Next” through the wizard.  Do not modify the component selection.  The instructions also said to restart the server after this wizard, which I did NOT, and the issue still was resolved even though I have not restarted.
