MDCS Issue: Client can't connect to server. Failing "LockDown Test"

I am resetting my MDCS server and I am running into a bit of difficulty with the process. This MDCS server was working until recently so I believe something has been updated that messed with the connections to the service, though I can't say what. So far, I have performed the "mdce install" and "mdce start" commands successfully, and normally I would be able to start jobmanagers but I can't. When I use the Admincenter I see that the host is recognized, but the MDCE service is unavailable. I ran the connectivity test and I get this error:
LockDown Test ERROR com.mathworks.toolbox.distcomp.admincenter.testing.infra.util.TestFailureException: Test execution on fsd0j5a02:27352 failed. Cause: com.mathworks.toolbox.distcomp.control.ControlExceptionFactory$HostPortException: An error occurred while connecting to the mdce service on the host fsd0j5a02.
Any suggestions on what might cause this error would be appreciated. The error message itself is not particularly revealing to me. The previous test indicated that the port was open, so I don't believe this is an issue with port 27352. Version is 2009a and 32 bit installation.
Thanks,
Stephen

  1. Are you running any firewalls? Software that might be acting like one? (Malware scanner, virus scanner -- they might also include a firewall)
  2. In Admin Center, there are a suite of connectivity tests (among other things). Do these pass or generate warnings? Look especially for DNS issues like proper name resolution.
  3. Is it possible that something else is taking the port? If you run "netstat -a" at a command prompt, you can see what is on each port.
It definitely sounds like the communication can't be established and that's what is causing the issue.

Note that I left out the switches to name the workers and job manager. You'll need those (although you likely already know the names)
