What is dsNcService.exe?

The genuine dsNcService.exe file is a software component of Network Connect by Juniper Networks, Inc..
The "dsNcService.exe" process is one component of software created by Juniper Networks for enterprises, institutions, or governments that have a Juniper-powered Virtual Private Network (VPN) and want to allow employees remote access and control of their company workstations. (It and one other component must be allowed through the firewall.) Juniper's approach is to download and install VPN access software onto a remote client computer, in "C:\Program Files\Juniper Networks\Common Files", each time that network's login page is visited. The download includes a Juniper-designed Uninstall program, which the user must invoke through the Control Panel's "Uninstall a Program" applet, to remove it before the network can be accessed again. Founded in 1996 with its corporate headquarters in Sunnyvale, CA, USA but having 16 global 24/7 technical support centers worldwide, Juniper Networks claims to have a central role in the accelerating global growth of the Internet and the Cloud through relentless innovation of hardware and software solutions that enable the many governments and top-ranked global business entities who are its clients to be innovators as well.

Best practices for resolving dsNcService issues

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