Tips and Tricks for:  .Net, C#, VB.Net,
Updater Application Block (UAB)

The Problem:   Updater Application block is Broken by BITS 2.0

BITS 2.0 adds additional security to Windows XP.  However, it breaks existing programs that rely on The Updater Application Block for automatic software distribution.   BITS 2.0 can be downloaded by Windows Update or added to your system when Windows XP Service Pack 2 is installed.

Solution: Either update the UAB (C#  only) or modify the registry to remove the new check..

There is a unsupported updated version of the UAB code that works with BITS 2.0.  You can find it on GotDotNet.  However, there is no VB.Net version of the code.

The alternative solution is to modifty the registry to add the entry UseLmCompat to the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\BITS

The attached zip file has a .reg file that makes the entry for you.  Although it's small, it must be in a ZIP to allow it through various firewall and antivirus programs.
