Dynamics Ax 4.0 Enterprise Portal--Windows SharePoint Services does not display the Enterprise Portal templates on the Custom tab.

This article is useful:
When the Enterprise Portal templates are not displayed even you deploy the Enterprise Portal software in the Microsoft Dynamics AX 4.0 client.
Windows SharePoint Services does not display the Enterprise Portal templates on the Custom tab.
You don’t receive the message 'DeploySiteDefinition:Success' on Update using Manage Deployments Form.

Cause:
Generally this problem occurs when the current user account does not have access to the file location.
May be Windows SharePoint Services 2.0 and Windows SharePoint Services 3.0 both are installed on the server.
May be the Windows SharePoint Services 3.0 is installed with an additional language package.

To solve this problem
1) you need to download a knowledge base update from Microsoft website. To download this extranet/partnersourse access is required.
Click here to down load.

2) Save the down loaded file in the 1033 folder of your installed WSS: 
The location would be
[Root drive:]\ProgramFiles\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\1033

3) Extract the down loaded file, and then copy the Webtempaxsitedef.xml file to the folders below:
[Root drive:]\ProgramFiles\Common Files\Microsoft Shared\Web server extensions\12\TEMPLATE\SiteTemplates\XML 
[Root drive:]\ProgramFiles\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\1033\XML

4) Open the Ax Application then press Ctrl + D to open the AOT.

5) Go to Web node then Web Files, click on Site Definitions, and then locate the site definition file for the language that is installed. For example, the site definition file for US-EN is AxSiteDef_1033_xip.

6) Right-click the site definition file, and then click Deploy.

7) Restart the IIS.

Now it should work.
