Cannot connect to MJS with parcluster

I'm working on setting up a cluster environment, but for some reason I can't get the client to communicate with the mdce service. When I try to validate the cluster profile, parcluster can't communicate with the cluster, with the following error. Both sides are running Matlab 2013a. There are no firewall blocking the traffic between the hosts, and nodestatus.bat seems to be working fine. What can I do to try to get this thing working?

Error using parcluster (line 53)
Could not contact an MJS lookup service on host '10.236.95.1'. Possible reasons for this problem are:

1. MJS has not been started, has crashed, or has been shut down.
2. A firewall is blocking communication between this computer and '10.236.95.1'.
3. This computer cannot resolve the hostname of '10.236.95.1', it resolves it to an incorrect IP address.
4. '10.236.95.1' resolves its own hostname to an incorrect IP address.
5. Network routers are unable to route traffic from this computer to '10.236.95.1'.

The hostname, 10.236.95.1, corresponds to the fully qualified hostname 10.236.95.1.
This computer resolves it to the IP address 10.236.95.1.

Nodestatus.bat says the following:

C:\Program Files\MATLAB\R2013a\toolbox\distcomp\bin>nodestatus.bat -remotehost 10.236.95.1 -infolevel 3
