My friend manish,<BR><BR>you didn't say anything about your OS, but this error has happened to me when I was trying to access an Microsoft Acess on Windows 2000. This happens because the default directory and file security configuration in the new Windows 2000 System is different from NT. On Windows NT the default security was Full Access to Everyone. Now it is only Full Access to the Creator, so the Web Service can't write or read from the database. You might want to change this security configuration to R/W Acess to Everyone or for the IUSR and IWDM_ users...<BR>That's it.
