Configuring BiztalkServer 2004

This may occur when applying a BizTalk configuration file in silent or interactive mode. The full error (from the log in silent) is:

Failed to deploy system assembly "C:\Program Files\Microsoft BizTalk Server 2004\Microsoft.BizTalk.GlobalPropertySchemas.dll". The rest of the error message is informative as well; giving you a hint on where to go:

“The network clients for the Distributed Transaction Coordinator (DTC) Network must have the remote clients/transactions option enabled. The partner transaction manager has disabled its support for remote/network transactions.“

This is a DTC issue; in this case, DTC isn't properly configured on a remote SQL Server. Help and troubleshooting will give you a text string containing “You must enable network clients DTC access before configuring BizTalk Server“. Check your installation steps and ensure you:

On the SQL Server, navigate to Component Services, Computers.
Right-click the My Computer icon and select Properties, MSDTC.
Click Security Configuration, Network DTC Access.
Ensure Network Clients is selected.
To save time, perform/confirm these steps on the BizTalk server as well.
