I have a Dell MPF 1815dn printer. I assume the DNSCST.exe file was installed with other driver files. I test printed a doc after ending the process of this exe file without problems. The file could control ink saving, or orientation and other features, these were not tested
As mentioned, it's part of the Dell All-In-One network scanning function. It allows the printer to find your computer as a destination when starting the scan from the printer's control panel. Without it, your computer will not appear in the computer list on the printer. No other functions are affected.

Best practices for resolving DNSCST issues

A clean and tidy computer is the key requirement for avoiding problems with DNSCST. 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.
