Error 1721 is a Microsoft error that is sometimes generated when you attempt to use an executable file called Cluster Administrator. The general text of Error 1721 is the following: "not enough resources are available to complete this operation."

How Did The Problem Occur?
When you use the Cluster Administrator to connect to a cluster
an error will occur if the proper parameters are not specified. One possible reason for the error is that you did not enter the parameter with quotation marks
so the command could not be read as a complete phrase for the search. This creates a problem with the available IP ports that would be used to establish a communication through the remote procedure call
especially if there are less than a hundred ports available to process the communication flow. Along with the failure to issue the request using quotation marks
there may also be some restriction on the available port ranges when the program was originally installed.
How Do I Fix the Problem?
One place to check for restrictions on the available ports is in the MSMQ
or Microsoft Message Queuing. There may also be a need to consider that other services make use of DCOM ports that may inhibit the ability to make use of the minimum number of ports. In order to correct the situation
there will be the need to modify the registry. Microsoft provides step by step procedures to accomplish the modifications.
One thing to keep in mind is that reconfiguring a registry can be a tricky task. Ideally
persons who are well versed in computer configuration should take care of modifying the registry. Making a mistake in the modifications could create other issues that would require a professional to resolve. Save the time and trouble
and get an expert to perform the necessary changes to the registry.
