If you install DBXL to Windows XP and you cannot query the Active
Directory Web service (ADUserInfo.asmx) you will have to manually
configure your machine’s ASP.NET account. To verify that this is the
problem, navigate to http://machine/QdabraWebService/ADUserInfo.asmx,
click GetMyInfo and Invoke. If you don’t get XML you will need to follow the configuration steps detailed in this document.
