"RemoteAnywhere" installs a webserver on this port. NeWS/OpenWin (Sun's older variation of X-Windows) uses this port.
Lineage also uses this port.
A number of trojan horses/backdoors use this port: TransScout, Der Spaeher, Fear, Force, GOTHIC Intruder, Insane Network, Last 2000, Real 2000, Remote Explorer 2000, Senna Spy Trojan Generator, Singularity
Backdoor.Fearic [Symantec-2002-080710-2744-99] (2002.08.07) - remote access trojan, affects all current Windows versions, opens ports 2000, 3456, 8811.
Trojan.Esteems.D [Symantec-2005-051615-2304-99] (2005.05.16) - trojan with keylogger capabilities. Uses port 2000/tcp to communicate with a remote host and send logged information.
Dark Colony game also uses port 2000 (TCP/UDP).
Unspecified vulnerability in the Session Border Controller (SBC) before 3.0(2) for Cisco 7600 series routers allows remote attackers to cause a denial of service (SBC card reload) via crafted packets to TCP port 2000.

SANS ISC: port 2000
Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify
a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly
used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol
on the Internet and any TCP/IP network. TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol)
and facilitates the transmission of datagrams from one computer to applications on another computer,
but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
