In yesterdays (4/14/2009) initial WSUSScn2.cab release from the MU/WU team, there was an issue causing the update for KB923561 for the Czechoslovakian language to be incorrectly detected and offered. This issue was addressed and a revision to this update was published. This revision also caused a new cab to created and released at 3:00pm Pacific Time. Just a heads up if you have questions about the new revised .cab, the revision for the KB923561 for “CZ” is the difference between the 2 versions.
Thanks very much,
The MU/WU team
