Being prompted for a Username & password even though we did not turn on security or set up security in MS Access; we were provided a MRAD SharePoint password & database password & now we have to use the MRAD SharePoint password to enter all MS Access databases; we have tried opening Access database in Exclusive mode to select "Unset Database Password" but the selection is not an option; instructions from Microsoft support were also not successful (start Office Access, tools, security, Workgroup Admin, join, browse to C:\Documents & Settings\your User name\Application Data\Microsoft\Access\System.mdw, ok, in Workgroup Admin box click ok, repeat); also thought the issue might be resolved by the Administrator of the SharePoint removing us from the Group & then adding us back in, but he feels that it is nothing to do on his part, but something on our end. Please advise
