SYMPTOMS
When you try to use the AutoDiscovery and Layout solution in Visio 2002, you may receive the following error message:

AD&L functionality is not available in this document because it is not connected to a database. Please re-open solution.



CAUSE
This issue may occur if the Microsoft Data Engine (MSDE) cannot locate the Adlclassmap.mdf file. This issue may also occur if you remove, and then reinstall MSDE.

When MSDE is removed from the computer, it does not remove the ADLclassmap database files such as Adlclassmap.mdf and Adl.mdf, that are created by the AutoDiscovery and Layout solution. As a result, these files remain in the :\Program Files\Microsoft SQL Server\MSSQL\Data folder on your hard disk, where   is the drive on which MSDE is installed. When you reinstall MSDE, MSDE does not recognize and use the database files although they exist in the same location.



RESOLUTION
To resolve this issue, delete the ADLclassmap database files. After you delete the database files, you can use the AutoDiscovery and Layout solution to perform a network discovery to create a new database:  Quit Visio 2002. Start Microsoft Windows Explorer, and then locate the following folder, where  is the drive on which MSDE is installed:



 Right-click the Adlclassmap.mdf file, and then click Delete. When you are prompted to confirm the deletion, click Yes. Right-click Adl.mdf, and then click Delete. When you are prompted to confirm the deletion, click Yes. Start Visio 2002.</li> On the File menu, point to New, point to Network, and then click AutoDiscovery and Layout.</li> On the AutoDiscovery menu, point to Discovery, and then click Discovery Wizard.

Follow the instructions that appear to perform a network discovery and create a database of devices that are found on your network.</li></ol>
