Fix Internet Explorer Printing Blank Pages

I just ran into an issue where three different clients in the same morning reported that Internet Explorer was printing blank pages.  A quick search on Google turned up the following article:

The problem specifically manifests itself by printing a blank page with a footer (if you haven’t turned them off) displaying the following line: “file:///C:/Users/userprofile/AppData/Local/Temp/Low/randomfilename.htm”.

To fix this issue, you’ll need to bring up a command prompt (but not with elevated permissions) and type the following commands:

mkdir %userprofile%\AppData\Local\Temp\Low
icacls %userprofile%\AppData\Local\Temp\Low /setintegritylevel low

I’ve also found some information from Microsoft’s site to fix the problem.  They even include a Microsoft Fix It utility to fix the problem automatically:

12/2/2014 UPDATE:
I recently had a client contact us about this very problem but the challenge was slightly different.  The web application (online credit card processing) was using framesets and IE was attempting to print an empty frameset.  Microsoft suggests turning on Compatibility Mode, however, I suggested:

  • Highlight what you’d like to print
  • Right click the selection
  • Click Print
  • Make sure to select “Selection” in the page range box
  • Click Print

Linux Tips & tricks

Edit files on the linux command line

To edit files on the command line, you can use an editor such as vi. To open the file, run

vi /path/to/file

Now you see the contents of the file (if there is any. Please note that the file is created if it does not exist yet.).
The most important commands in vi are these:
Press i to enter the Insert mode. Now you can type in your text.
To leave the Insert mode press ESC.
To delete the character that is currently under the cursor you must press X (and you must not be in Insert mode because if you are you will insert the character x instead of deleting the character under the cursor). So if you have just opened the file with vi, you can immediately use x to delete characters. If you are in Insert mode you have to leave it first with ESC.
If you have made changes and want to save the file, press : x (again you must not be in Insert mode. If you are, press ESC to leave it).
If you haven’t made any changes, press :q to leave the file (but you must not be in Insert mode).
If you have made changes, but want to leave the file without saving the changes, press :q! (but you must not be in Insert mode).
Please note that during all these operations you can use your keyboard’s arrow keys to navigate the cursor through the text.

Exchange Tips & tricks

Exchange 2010 Database size

  1. Review the Purge items from the Recoverable Items folder. For details, see Clean Up the Recoverable Items Folder.
  2. Yes ESEutil /D is the command
  3. Safe?  Yes relatively, however, that said
    1. before you ever run any type of utility against an Exchange database you should back it up just in case something goes sideways.
    2. you will need 110% of the EDB size to perform the defrag and
    3. during the time its being defragged ALL users for that database will be unable to connect.
  4. Time, well this depends upon many factors, i.e. CPU, Disk Speed, Memory, other processes etc.  Basically I would plan to spend at least a full day on it.  But whatever you do you need to be patient because it does take time to complete.
  5. Personally I think you would be better off to create a NEW database and use the New-MoveRequest so check out these two articles and since these will allow you to keep the system up and running while the data is being moved, however it does require more disk space until the process is done and then you can drop the old DB to gain all the space back.
