Product/Feature	Web Application Proxy
Severity	Warning
Category	Configuration

Issue

A cluster of Web Application Proxy servers is deployed and DirectAccess is also installed on this server.

Impact

Web Application Proxy does not support this configuration and might not work as expected.

Resolution

Consider uninstalling DirectAccess from this server.

When Web Application Proxy is deployed in a multiple server deployment, it cannot be deployed on a server that also has DirectAccess installed. You must uninstall either DirectAccess, or Web Application Proxy. The following table shows the supported deployments:

DirectAccess	VPN	Web Application Proxy
Single server deployment	Single server deployment	Single server deployment
Multisite deployment	Multiple server deployment	Not supported on the same server
Not supported on the same server	Multiple server deployment	Multiple server deployment
Cluster deployment1	Multiple server deployment	Multiple server deployment2

Note

1—In a pre-existing DirectAccess cluster deployment, you can install Web Application Proxy only using Windows PowerShell. 2—In a pre-existing multiple server Web Application Proxy deployment, you can install DirectAccess only using Windows PowerShell.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

To uninstall DirectAccess

1. On the Web Application Proxy server, open the Remote Access Management console: On the Start screen, click the Apps arrow. On the Apps screen, type RAMgmtUI.exe, and then press ENTER. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.

2. In the Remote Access Management console, in the navigation pane, click DirectAccess and VPN.

3. In the Tasks pane, click Remove Configuration Settings.

4. On the Confirm Remove Configuration dialog, click OK.

5. On the Removing Configuration Settings dialog, make sure the configuration was removed, and then click Close.
