I ever try somthing with the vcdb.properties file and the vmware employee control it also.
See my file:
usevcdb=true
url=jdbc:sqlserver://localhost\\VIM_SQLEXP;databaseName\=VIM_VCDB;integratedSecurity\=true
dbtype=mssql
driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
I search for the sql connection on the server because no process listen on the port 1433 and vpxd listen on 1434 (normally, it is the port for sql browser). Have you this also on your server ? (command "netstat -abn").
