I have developed a web application in ASP with database in MS Access 2002 at the back end. Whenever I want to update or add a record in my database, I get following error message:

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] Cannot update. Database or object is read-only.
/final2/VerifyCustomer.asp, line 132

This problem is experienced while running my application in Windows XP (with IIS ON) only. The same application runs perfect on Windows 2000 server. Plz help as I can't switch to 2000 at this stage of my project.
