Some of our duet customers are facing problem while installing Duet Request Handler. So I thought of writing the installation procedure to help them out.

Here is the first screen that come up when you run the Setup file and Click Next

In the designated account text box you have to enter the user name in the form of domain\user. This domain account will be used to send the mail messages from the exchange server.

Enter the domain user's password in the Password text box and the name of the exchange server in the Exchange server text box.

Note : If your exchange server is serving webdav at some other port than 80 please specify port number with the exchange server. Exchange server name should be exactly the same where your mailbox is residing.

e.g.

Exchange Server:
exchangerServer:8081

Setup validates the domain account in the active directory and attempts to send webdav request to the exchange server. If any of these steps fails it will not allow the user to continue.

You can specify the Port number where you want request handler to be running in the next screen. (Note: setup only creates the virtual directory. You should create a different website yourself if you dont want the request handler to run in the default website)

If everything goes fine you are ready to install. Click next and you are done.

Troubleshooting: If it throws a message saying "Designated account credentials could not be authenticated" you should:

• Make sure you entered the correct username and password.
• Check if the user exist in the AD and exchange server.
• Make sure machine is connected and added to the appropriate domain and you have access to the exchange server machine.
• Make sure your are logged on to the machine using the domain credential not (local machine credentials).
• Make sure username and password doesn't contain space characters in the start and the end.
• Check if user has access to Global catalog (GC).
• Check if webdav service is enabled on the exchange server. Try to access http://exchangeserver:port/exchange/user using the credential you specified in the setup screen. If you can't access it, that means you probably have some issue with exchange server configuratuin and contact your admin to configure exchange server for the necessary setup and permissions.
• Make sure windows authentication is enabled on the exchange server.
• Forms based authentication is not supported in this version of the request handler.
