User Comments

Das Programm ist nicht potentiell gefählich. Da es jedoch auf Port 5002 und 6002 lauscht, kann es von Schadsoftware zur Spionage benutzt werden. In diesem Fall gibt sich das Programm als nidmsrv.exe aus. Die Datei sollte regelmäßig überprüft werden. Wenn sie nicht benötigt wird sollte sie sogar am besten gelöscht werden, da sie nicht unbedingt für Windows wichtig ist.

Best practices for resolving nidmsrv issues

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