Technical description for port 6004:

Port 6004 is one of the default ports used in Microsoft Exchange Server. There are two main servers attributed to this port, namely DSProxy and ncacn_http.
DSproxy uses port 6004 as a proxy port, mainly used by Microsoft Outlook Anywhere to synchronize with mailbox information found on a remote Exchange Server via HTTP.
A client terminal initiates several HTTP sessions on port 6004 on the Exchange server. One HTTP service for RPC requests to the server and another for RPC requests from the server.
The RPC proxy server extracts the RPC requests from the HTTP service on port 6004 and forwards it to the Exchange server using the same route. These functions allow remote users to access their email on the Exchange server via port 6004 using POP, IMAP, OWA, Active Sync, and RPC/HTTP for Outlook Anywhere applications.
