Chapter 29: Troubleshooting Database Connections; Troubleshooting Permissions Problems - MACROMEDIA DREAMWEAVER MX 2004-USING DREAMWEAVER Use Manual

This chapter describes some common problems you might encounter after creating a database
connection, and describes ways to fix them.

Troubleshooting permissions problems

One of the most common problems is insufficient folder or file permissions. If your database is
located on a Windows 2000 or Windows XP computer and you receive an error message when
you try to view a dynamic page in a web browser or in Live Data mode, the error may be due to a
permissions problem.
Here are possible error messages pointing to a permissions problem:
•
Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC
Microsoft Access 97 Driver] Couldn't use '(unknown)'; file already in use.
•
Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC Microsoft
Access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is
already opened exclusively by another user, or you need permission to view its data.
•
Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC
Microsoft Access 97 Driver] Couldn't lock file.
The Windows account attempting to access the database doesn't have sufficient permissions. The
account might be either the anonymous Windows account (by default, IUSR_computername) or a
specific user account, if the page has been secured for authenticated access.
You must change the permissions to give the IUSR_computername account the correct
permissions so the web server can access the database file. In addition, the folder containing the
database file must also have certain permissions set to write to that database.
If the page is meant to be accessed anonymously, give the IUSR_computername account full
control to the folder and database file, as described in the procedure below.
Additionally, if the path to the database is being referenced using UNC (\\Server\Share), make
sure the Share Permissions give the IUSR_computername account full access. This step applies
even if the share is on the local web server.
If you copy the database from another location, it might not automatically inherit the permissions
from its destination folder. You might have to change the permissions for the database.
