Remote Administrator 3.0 Server. It allows to remotely manage this computer by the Remot Administrator Client.
I use it (Radmin) and it is great to remote into another computer. If you or your system admin did not install it, you have a problem.

Remote Administrator - Remote Control Tool, wenn ihr es nicht installiert habt, könnte es als "Trojaner" in Benutzung sein. (RAdmin startet ein Tray-Icon. Wenn dies nicht da ist, handelt es sich wahrscheinlich um eine gefährliche Version)
  Alexander Straub  
i have used it for about 4 years. It is the server side of a simple remote control package. Make sure you or your sysadmin downloaded from a reputable place and install it yourself.

Best practices for resolving rserver3 issues

A clean and tidy computer is the key requirement for avoiding problems with rserver3. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the rserver3.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
