Harmless file required for Diskeeper defrag product. Some problems with various versions of older products hogging system resources. Newest product (Condusiv Technologies Diskeeper 12) works well with lots of configuration and scheduling options. Benefits SSD as well as spinning HD.

It's an essential part of Diskeeper and it is in your PC's interests to allow Diskeeper to run in the way it was designed to. Yes, it uses resources in the short term but it will free resources in the long term. Denying it port access will achieve nothing, almost certainly you have other software running that also keep a port open.
**IMPORTANT** Diskeeper definitely listens on TCP port 31038 on ALL interfaces, not just loopback, meaning it is possible for anybody with access to your network to make a connection to your pc without your knowledge. This port is open at ALL times, no matter what settings are used. There is at least one known exploit that can be easily used to access protected data this way. It is unlikely that DK is abusing it, but there is NO LEGITIMATE reason for this software to exhibit that behavior. It is the result of poor programming at best. If you still use it, be sure you're behind a good firewall.

By DK's own admission this program phones home using port 31038 which it holds OPEN all the time to "LISTEN". It also addresses external communications (such as checking for product updates or transmitting report data to a Diskeeper Administrator console. I don't want this thing transmitting ANYTHING to an "Administrator". Oddly enough DK has a patch for this thing allegedly to alleviate the security hole it creates. Trust it if you want to but it's not for me. I don't care what Google says.

Best practices for resolving DKService issues

A clean and tidy computer is the key requirement for avoiding problems with DKService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

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