whenever i try command mpiexec -n 4 testmpi.exe

Unable to connect to 'RIJDZUAN-PC:8676', sock error: generic socket failure, error stack: MPIDU_Sock_post_connect(1200): unable to connect to RIJDZUAN-PC on port 8676, ex hausted all endpoints (errno -1) MPIDU_Sock_post_connect(1247): unable to connect to RIJDZUAN-PC on port 8676, No connection could be made because the target machine actively refused it. (errno 10061)

and when i try to smpd -install or smpd -start giving me

OpenSCManager failed: Access is denied. (error 5)

i believe i'd already registering mpiexec over mpiexec -register

how to resolve this?

I got this message as well. Turns out when the installer says "successful" but smpd is not running, then the install is silently incorrect.

Copied (and slightly altered) from here

  1. Uninstall previous version of MPICH2
  2. Open an admin command prompt by right-clicking on the command prompt icon and selecting "run as administrator"
  3. Run "msiexec /i mpich2-1.3.2p1-win-ia32.msi" from the admin command prompt to install MPICH2
  4. During installation select that MPICH2 be installed for "Everyone" for all users.
  5. Run wmpiconfig and store username/password. EDIT: Use your REAL windows login name and password.
  6. Add "C:\Program Files\MPICH2\bin" to system Path and EDIT: no need to reboot
  7. Check smpd using 'smpd -status'. it should return 'smpd running on $hostname$'
  8. To test execution environment, go to the directory $MPICHROOT\examples and run cpi.exe using: 'mpiexec -n 4 cpi'

You can follow the above steps even if you are not logged in as an admin user. Just make sure to follow step 2 closely. If you see 

OpenSCManager failed: Access is denied

It probably means you are not on an admin command prompt. If step 7 checks out, you should be good to go.

run CMD as an admin, and after words run the smdp -install comand.
