title: OLE DB Provider for ODBC Drivers Error "80004005'
body: <p>I have to move some customer sites from a very old IIS Server to a newer one, and some sites have troubles to work in the correct way. Most of them complain about a failure called:</p>
  <blockquote>
  <p>Microsoft OLE DB Provider for ODBC Drivers error '80004005'</p>
  <p>[Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified.</p>
  </blockquote>
  <p>I've read on the internet that this could depend on missing rights given to the user; other sites states that a Temp folder is missing (I can't imagine that this is right)… There are several other &quot;solutions&quot;:</p>
  <p>Open the rights for everyone on the server (as someone stated) is not an option for me. Also it is very painful to give explicit rights to every customer (there are several customers which needs the rights).</p>
  <p>Do you know an easier solution, a similar way, or an alternative?</p>
