Hallo Christof,

falls nicht schon gelesen hierzu noch dieses aus der technical database von IBM : http://www-912.ibm.com/supporthome.n...d?OpenDocument

dieser Absatz z.B. :

IBM suggests that these keys retain default settings. While most of these keys are accessed for READs, the first three are also updated. If the user signed on Windows cannot write to the first three keys listed, Client Access does not work.

In previous versions of Client Access Express (V4R4, V4R5, and so on), Client Access also wrote to the classes root hive. In Client Access Express V5R1 Service Pack 2 (SI01907), Client Access was changed to minimize interaction with classes root and maximize use of the keys HKLM\Software\IBM\Client Access and HKCU\Software\IBM\Client Access Express. These keys are obviously meant for use by Client Access. They are less likely places for Windows Administrators to add extra security.
