So I went into Component Services and enabled DTC for network access as described here: (WS.10).aspx No errors from the Configuration Wizard itself, everything runs along normally.
Please enable DTC for network access in the security configuration for MSDTC using the Component Services Administrative tool. During this phase I find this error in the event log: Application Error Event ID: 3 Source: Forefront Identity Manager Description: : System.ArgumentException: Unable to open database connection Parameter name: connectionString -> : Network access for Distributed Transaction Manager (MSDTC) has been disabled. After the Sharepoint Products Configuration Wizard completes, I launch the setup wizard from Central Administration. Ok, this is my second installation of the beta and I have seen the same things both times.
