MS06-034 installation fails on computers that have Windows Server 2003 SP1
installed
Symptoms

Users may experience an issue when they install the MS06-034 security update
by using Windows Update or Auto Update. The update will appear to install
correctly on computers that are running Windows Server 2003 SP1. However, if
the update is installed when IIS is being used, the Asp.dll file is not
updated. This problem occurs because IIS locks the Asp.dll file. This lock
prevents the update from installing correctly.


Resolution

This problem was corrected on July 17, 2006. Users who experience this
problem can install the package again from Windows Update. Alternatively,
users can manually download the update from the Microsoft Download Center.
