FYI - Problem I hit and the solution...
-----------------------------
Issue:
When I try to connect with runtime remotely from a Win 2K workstation to the workflow server, I get the following error:

FMC_API_ERROR_COMMUNICATION : Communication Error

Solution:
Check the PATH variable to see what workflow directory it's referencing. In your workflow directory, under bin, there are MQClient and MQServer directories. If you installed the full MQ software (i.e. Server/Queue Manager) on this machine, then the path may be referring to the MQServer directory instead. Make sure the MQClient directory is used in the PATH instead. The runtime directory uses a client connection.

The above error FMC_API_ERROR_COMMUNICATION is quite common and there are many reasons for getting this error. It should be noted that the above solutions exact problem is:
If you have both MQ Server and MQ Client on the box where MQWF client is and MQWF configuration is created in such a way that the WF client and WF server are supposedly communicating with MQ Client.

If this is the scenario then the remedy is as suggested above.
