What is nsd.exe?

The genuine nsd.exe file is a software component of IBM (Lotus) Notes by IBM.
The Notes System Debugger (NSD) is a troubleshooting tool in the IBM Lotus Notes/Domino enterprise e-mail and collaboration system where enterprise e-mail is maintained on a centralized server and accessed by client PC's and mobile devices. Uninstalling the Client side of Notes as a whole, (from version 8.0 forward), consists of deleting the folder created at installation by unzipping the Eclipse IDE (which is in Java) plus special plugins. Specifically uninstalling the NSD requires a network administrator. The NSD generates a logfile for analysis by support desk personnel. If it launches automatically it is a sign that the Notes/Domino environment is seriously compromised. It can also be run manually when troubleshooting, on a client or server. IBM is headquartered in Armonk, NY, USA, and was originally formed from several companies in 1911 by its founder, Thomas Watson, who took its current name from a Canadian subsidiary in 1924. It has continually shifted its focus away from manufacturing towards enterprise solutions and cloud computing.

Best practices for resolving nsd issues

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