You may find that you cannot open a Microsoft Office Visio 2003 XML drawing (.vdx file) that is located in the document library of a Microsoft Windows SharePoint Services 2.0 Web site. When you connect to the document library, and then click the link to the Visio XML drawing, you receive the following error message:

This issue may occur if either one of the following conditions is true:

• Microsoft Internet Explorer associates the .vsd extension with the .vdx file that you want to open. The .vsd and .vdx extensions use the same MIME type setting of "application/vnd.visio" (without the quotation marks). In situations when a file is saved to the local disk, Internet Explorer may associate the .vsd extension instead of the .vdx extension with a .vdx file.
• The .vdx extension is not registered in Windows SharePoint Services 2.0 as a file type that you can edit by using Visio 2003. By default, the .vdx extension is not configured with the Edit in Microsoft Office Visio option in Windows SharePoint Services 2.0.

To work around this issue, use one of the following methods, as appropriate to your situation.

Method 1: Modify the MIME mapping for the .vdx extension in Microsoft Internet Information Services (IIS) 6.0

To modify the MIME mapping for the .vdx extension in IIS, follow these steps:

1. Start Internet Information Services (IIS) Manager.
   1. Right-click ServerName, and then click Properties.
   2. Click MIME Types.
   3. In the MIME Types dialog box, click the entry for .vdx, and then click Edit.
   4. In the MIME type box, type application/vnd.visio.xml, and then click OK.
   5. Click OK, and then click OK.
2. Restart IIS. To do so, follow these steps:
   1. Click Start, and then click Run.
   2. In the Open box, type cmd, and then click OK.
   3. At the command prompt, type iisreset, and then press ENTER.
   4. Type exit, and then press ENTER to exit Command Prompt.

Method 2: Configure the .vdx extension to use the Edit with Microsoft Office Visio option in Windows SharePoint Services

Add the .vdx extension to the list of file types in the DocTypes.xml file that use the Edit with Microsoft Office Visio option. After you do so, when you click a Visio XML drawing (.vdx) file in the document library of a Windows SharePoint Services 2.0 Web site, the Edit in Microsoft Office Visio command is displayed on the submenu that appears.

To add the .vdx extension to the list of file types that use the Edit with Microsoft Office Visio option, follow these steps:

1. Edit the Docicon.xml file to include the .vdx extension. To do so, follow these steps:
   1. Start Notepad, and then open the Docicon.xml file. The Docicon.xml file is located in the following folder on the Web server:
      Drive:\Program Files\Common Files\Microsoft Shared\Web server extensions\60\Template\xml
   2. Locate the following line:
      <Mapping Key="vdx" Value="icvdx.gif"/>
   3. Edit the line that you located in step 1b so that it reads as follows:
      <Mapping Key="vdx" Value="icvdx.gif" EditText="Microsoft Office Visio" OpenControl="SharePoint.OpenDocuments"/>
   4. On the File menu, click Save, and then quit Notepad.
2. Restart IIS. To do so, follow these steps:
   1. Click Start, and then click Run.
   2. In the Open box, type cmd, and then click OK.
   3. At the command prompt, type iisreset, and then press ENTER.
   4. Type exit, and then press ENTER to exit Command Prompt.
