When doing a simple open of a recordset via rs.Open strSQL,strDSN,0,1, I get the Provider error &#039 800040e4d&#039, Authentication failed. Now the kicker. This app has been on the NT box for two months without any prior incidents. Is it possible someone has been mucking with the NT administration? Has anyone encountered this before? If so, what to do...<BR><BR>Thank you for your help.<BR>Markus<BR>
