What does the following server log error message refer to?
HTTP-E-ENOTFOUND-The URL "/InCharge/V1.0/dmsocket/domain?<domain>" was not found on this server.
There are a number of scenarios for which this error may occur, however generally this is due to an external client (broker, domain, gui etc) attempting to connect to a domain via a port which is now used by a different domain.
To identify the actual external client you may use "snoop" or other packet tracing utilities.
