No Web Parts are displayed in the online Web Part gallery, or you cannot retrieve content in the Content Editor Web Part in Windows SharePoint Services (912060)

RESOLUTION

To resolve this issue, modify the Web.config file for each virtual server for which you want to enable an online Web Part gallery that is outside the firewall. In a server farm environment, you must modify the Web.config file for every virtual server in every front-end Web server in the server farm.

Use the procedure that is appropriate to the version of ASP.NET that is running on the server.

ASP.NET 1.1

To specify proxy server settings when the server is running ASP.NET 1.1, follow these steps:

1. On the front-end Web server, start Notepad.
2. Locate the folder that contains the virtual server for which you want to enable access to the online Web Part gallery. Then, open the Web.config file for that virtual server. The Web.config file is located in the following folder:

   \Inetpub\Wwwwroot

3. Locate the /system.web entry near the end of the Web.config file.
4. Add the following lines to the Web.config file immediately after the /system.web entry, where ProxyServer is the name of the proxy server, and port is the name of the port that you are using:

   <system.net>  
      <defaultProxy>  
      <proxy proxyaddress="http://<ProxyServer>:<port>" bypassonlocal = "true"/>
      </defaultProxy>
   </system.net>

5. Save the Web.config file, and then quit Notepad.
6. Repeat steps 1 through 5 for each virtual server for which you want to enable access to the online Web Part gallery.

ASP.NET 2.0

To configure proxy server settings when the server is running ASP.NET 2.0, use one of the following methods.

Method 1: Modify the Web.config file and the Wss_minimaltrust.config file

To specify proxy server settings in the Web.config file, follow these steps:

1. Modify the Web.config file. To do this, follow these steps:
   1. On the front-end Web server, start Notepad.
   2. Locate the folder that contains the virtual server for which you want to enable access to the online Web Part gallery. Then, open the Web.config file for that virtual server. The Web.config file is located in the following folder:

      \Inetpub\Wwwwroot

   3. Locate the /system.web entry near the end of the Web.config file.
   4. Add the following lines to the Web.config file immediately after the /system.web entry, where ProxyServer is the name of the proxy server, and port is the name of the port that you are using:

      <system.net>  
         <defaultProxy>  
         <proxy proxyaddress="http://<ProxyServer>:<port>" bypassonlocal = "true"/>
         </defaultProxy>
      </system.net>

   5. Save the Web.config file, and then quit Notepad.
   6. Repeat steps 1a through 1e for each virtual server for which you want to enable access to the online Web Part gallery.
2. Modify the Wss_minimaltrust.config file. To do this, follow these steps:
   1. On the front-end Web server, start Notepad.
   2. Locate the Drive:\Program Files\Common Files\Microsoft Shared\Web server extensions\60\Config folder, and then open the Wss_minimaltrust.config file.
   3. Locate the SecurityClasses entry in the Wss_minimaltrust.config file.
   4. Add the following lines to the Wss_minimaltrust.config file immediately after the SecurityClasses entry:

       <SecurityClass Name="ReflectionPermission" 
      Description="System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, 
      PublicKeyToken=b77a5c561934e089"/>
      
      

   5. In the Wss_minimaltrust.config file, locate the PermissionSet entry, where Name="ASP.Net".
   6. Add the following lines to the Wss_minimaltrust.config file immediately after at the end of the section for the PermissionSet entry, where Name="ASP.Net":

      <IPermission class="ReflectionPermission"
                                          version="1"
                                          Flags="Members"
                                  />
      
      

   7. Save the Wss_minimaltrust.config file, and then quit Notepad.

Method 2: Use ASP.NET 2.0 Web Proxy Auto-Discovery

To use ASP.NET 2.0 Web Proxy Auto-Discovery, specify proxy server settings in Microsoft Internet Explorer for the application pool account that Windows SharePoint Services is running as. You do not have to modify the Web.config file or the Wss_minimaltrust.config file. To specify proxy server settings in Internet Explorer, follow these steps:

1. Log on to the front-end Web server by using the application pool account.
2. Start Internet Explorer.
3. On the Tools menu, click Internet Options, and then click the Connections tab.
4. Click LAN Settings. In the Local Area Network (LAN) Settings dialog box, click to select the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections) check box.
5. Specify the proxy server settings, and then click OK two times.

Note You can specify per-machine proxy server settings by using a policy setting. For more information about how to do this, visit the following Microsoft Web site:
