"Unexpected Error" Message When Running the Sample Applications

Server Checklist

• If you re-install IIS, you must re-install Remote Data Service afterward.
  
  
• If you are using Microsoft SQL Server as your back-end data source, use Microsoft SQL Server 6.5, Service Pack 2 or later.
  
  
• Ensure that the ODBC DSNs are System DSNs and not User DSNs. The Anonymous user logging on through IIS can view only System DSNs.
  
  
• Check that the anonymous account that your WWW service uses is a user on your domain that has NTFS permissions to all the relevant servers and directories. Finally, verify that the password for this anonymous account hasn't expired.
  
  
• Because Remote Data Service is installed in the C:\Program Files\Common Files\System\MSADC directory, check that the Anonymous user from the IIS Service Manager can access this directory. It should have both Read and Execute access.
  
  
• If you have trouble with Remote Data Service DLLs and sample applications, re-register the DLLs by using Regsvr32.exe.
  
  
• If you are writing your own business objects, place your Active Server Pages script files (.asp) in a directory that gives the Anonymous user (in IIS) Execute permission.
