DCOM and OpenMPI

Question

I did the DCOMCNFG with both the launch and the remote access permissions, granting my local logon on each node . Have OpenMPI_v1.6.1-x64 installed in root and remote machines. HAve specified the path of .exe in the target node. But while running the .exe from root node with mpirun. I am getting the following error:

D:\x64\Release>mpirun -np 2 -hostfile myhostfile.txt MPISample.exe
connecting to n1234
username:toney.mathew

Save Credential?(Y/N) n
[n1205:04420] Could not connect to namespace cimv2 on node n1234. Error code =-2147023174

mpirun was unable to start the specified application as it encountered an error.
