The transaction manager has disabled its support for remote/network transactions

I have installed a totally clean Umbraco with nothing in it. Not even Runway.

Then I wanted to try out the uCommerce Beta 2. But the installer failed, with this error message:

Server Error in '/' Application.
The transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D024)

Version Information: Microsoft .NET Framework Version:2.0.50727.3074; ASP.NET Version:2.0.50727.3601

I am running Windows Server 2008, and my database is placed on a server running Windows Server 2003. And there are no connection problems between the two servers.

I don't know how to get around this...

    We're aware of the issue. The transaction support in .NET will escalate transactions to a distributed one, which requires Microsoft Distributed Transaction Coordinator to be enabled. We'll remove the TransactionScope in the next release. In the meantime you can follow these steps to get it working:

    First verify the "Distribute Transaction Coordinator" Service is
    running on both database server computer and client computers
    1. Go to "Administrative Tools > Services"
    2. Turn on the "Distribute Transaction Coordinator" Service if it is not running

    If it is running and client application is not on the same computer as
    the database server, on the computer running database server
    1. Go to "Administrative Tools > Component Services"
    2. On the left navigation tree, go to "Component Services > Computers
    > My Computer" (you may need to double click and wait as some nodes
    need time to expand)
    3. Right click on "My Computer", select "Properties"
    4. Select "MSDTC" tab
    5. Click "Security Configuration"
    6. Make sure you check "Network DTC Access", "Allow Remote Client",
    "Allow Inbound/Outbound", "Enable TIP" (Some option may not be
    necessary, have a try to get your configuration)
    7. The service will restart
    (This is the thing drove me crazy before)

    On your client computer use the same above procedure to open the
    "Security Configuration" setting, make sure you check "Network DTC
    Access", "Allow Inbound/Outbound" option, restart service and computer
    if necessary.

    On you SQL server service manager, click "Service" dropdown, select
    "Distribute Transaction Coordinator", it should be also running on
    your server computer.

    A reboot might be needed as well.
