Block Access to Websites using HOSTS file !!

A website can be blocked on any Windows computer by editing the hosts file.

Locate the hosts file in Windows Explorer.

• Windows XP and later versions: C:\WINDOWS\system32\drivers\etc\
• Windows 2000 & NT: C:\WINNT\system32\drivers\etc\
• Windows 98 & ME: C:\WINDOWS\

Navigate to the proper directory using Windows Explorer. Double-click the hosts file. Choose Notepad from the list of programs to open the file and edit it in Notepad.

Find the line below:

• 127.0.0.1 localhost

Right underneath it, add the following lines (replacing badsite.com with the site you want to block):

• 127.0.0.1 badsite.com
• 127.0.0.1 www.badsite.com

Click on the File menu and click Save. Close the file. 

The site should be blocked in all web browsers and now instead of trying to access that site, the computer will redirect you to the localhost.

Issues opening Excel attachments

Clear Outlook’s Secure Temp folder

Main possible cause that Excel attachments are not opening correctly or with an error is because of other Excel files or templates in Outlook’s Secure Temp folder. 

The Secure Temp folder is the folder that Outlook uses to (temporarily) store attachments to that are being opened directly from within Outlook. Under certain conditions, this Secure Temp folder is not always cleaned correctly. 

In that case, you can clean it manually and see if the attachment is opened correctly now.

The folder location is stored in the registry in the following key;

Outlook 2013	HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Security

Offline Address Book Fails to Download in Exchange 2010

I found that this was caused by the configuration of the redirect changing the security permissions on the web.config file within the OAB virtual directory.   To fix the problem, browse to the OAB virtual directory and re-add the authenticated users group to "read" and "read and execute" permissions on the web.config file.    

Here are the corrected permissions:
