I have tried this with both Beta 6 and Beta 7. I am getting the 0x8004105C error on my network install/shared authentication installation. 1. I have tried installing Beta 6 and Beta 7 on the server. 2. Duxbury runs fine on the server with either version. 3. I "misexec /a" to get the deployment installation. 4. During the build I tried it both ways with the DNS name and IP address. 5. During the build I make sure that the include embosser definitions check box is unchecked to prevent a previous error that prevented the client from installing at all. 6. Installation on the client is successful, but I always get the 0x8004105C Authentication error everytime I try to launch Duxbury. Please find attached the latest install log from a Beta 6 install with Beta 6 on the server.
