How to change the default timeout period for the Web Search

Scenario 

Your users are reporting that they are receiving a message from the Exclaimer Mail Archiver Web Search that they have been logged out due to inactivity when they leave the Web Search logged-in for a period of time. Or in some scenarios, your security compliance officer has requested that, for security reasons, the session expires in a shorter period of time.

Reason

By default, if your users leave the Exclaimer Mail Archiver Web Search logged in and unattended, their session will timeout and they will be prompted to login after a period of time. This is for security reasons as it prevents unauthorized users from being able to search your email archive. For example, a computer is left unlocked in the office, or if your user logs in from a public internet cafe.

Timeouts differ depending on what the user selects, whether they are using a Public or Private computer on the Exclaimer Mail Archiver Web Search login screen.

By default, the timeouts are:

• Public Computer: 15 minutes
• Private Computer: 8 hours

If required, you can increase or decrease the timeout periods from their default values.

Resolution

To change the value of the timeout periods:

1. Launch the  RegEdit (Registry Editor).
   
   
   Warning: Windows Registry modifications should always be approached with extreme care - serious problems can occur if you modify the Windows registry incorrectly!
   
   We strongly advise you to back up the Windows registry before any modifications are made - in doing so you will have the option to restore the backup if a problem occurs.
   
   For more information, see How to back up and restore the registry in Windows.
2. Browse to the following registry subkey: 
   
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Exclaimer Ltd\Mail Archiver 1.0\WebSearch
3. From the Edit menu, select New then select DWORD (32-bit) Value.
   
   
4. Enter the DWORD name as PrivateComputerTimeout and press [Enter].
   This is to set the timeout for a Private computer.
   
   Note: To set the timeout for a Public Computer, enter the DWORD name as PublicComputerTimeout and press [Enter].
    
5. To edit the value, you can either right-click the PrivateComputerTimeout and select Modify or double-click PrivateComputerTimeout.
   
   The Edit DWORD (32-bit) Value window is displayed.
   
   
6. Select Base as Decimal and enter the value in minutes you wish to timeout after.
   For example, 15 minutes.
   
   
7. Reset Internet Information Services (IIS) for the change to take effect.   
   
   To do this:
   - From the Start menu, click Run. 
   - Enter IISReset then click OK.
