Metastorm BPM 9.0 - Deployment fails and Net.Tcp Port Sharing Service stops

I'm having a problem with a Metastorm BPM 9.0 installation on Windows XP SP3 configured to use a TCP/IP connection.

SQL Server is  running as are the Metastorm engine and deployment and Net.Tcp Port Sharing services are up and running.

When I try to deploy a project the Net.Tcp Port Sharing Service stops and the deployment operation fails with the following message:

    Error    03/31/2011 12:36:11 PM            The message could not be dispatched to the service at address 'net.tcp://cwsxw31791/Deployment/DeploymentService'. Refer to the server Event Log for more details        

The relevant Event Log entry isas follows:
