Manages your homenetwork and also sets it up
Network Magic is a free and useful software that allows 2 or more computers to be interconnected. For the average home the free network magic is sufficient however for the avid user across multiple domains will want to extend this program to the full featured version.

appeared shortly after installing USB wireless network card, taking upto 100% of my resources
Pure Networks installs it, it is required for managing your home network. Don't uninstall it.

Linksys packages this app with the USB wireless card I bought and returned. It's behavior is *extremely* suspicious, including accessing explorer.exe in memory and using a global DLL hook for likely keylogging. Not only should one *never* trust this program, but I advise complaining to linksys, and question whether it is in fact performing unlawful surveillance.
Recently my boss installed Classroom Spy Pro on all of the computers in the office without notice. I realized this program was installed on my pc, and since I log in as the admin, I could delete the classroom spy files from my pc, but I realized that something else was letting my boss view my pc, and as I checked, it was the process of nmsrvc.exe which was letting him use my free port. I found one in System32 and one in Program Files. Anyone knows how one can abuse a verising signed file?
I too believe it is suspicious. I didn't delete it but I stopped from running.

Be Very Afraid of Cisco-Linksys NMSRVC.EXE, it scans your network for devices and ports and connects to them and uploads data about your machine. This is definitely unethical and unauthorized RETURN THE DEVICE like I did!

It is very dangerous
It eats up all my system resources and slows everything I do down.
When I moved my PC, and connected it directly to my router, so that I no longer needed my CISCO Linksys RangePlus Wireless Network USB Adapter, I began getting a persistent startup error message from the program nmsrvc.exe, that memory at a certain address could not be read, and I also got a second error message about a Pure Networks Platform Service that encountered a problem, that needed to close. After reading other people's comments on this page about nmsrvc.exe, I have a feeling that this file is no longer essential, and no longer needs to run.
My system (i7 MS-W7Pro) was crawling. nmsrvc was 1 or 2 for CPU time but only a 2% or less load, but it was number 1 accessing the SSD constantly. It worries me that a network app was always scanning my disk. I did not appear to be uploading my data since the network was very quiet. I stopped nmsvrc and everything is back to being really fast. Linksys Advisor stopped working, no loss there. Access to my NAS farm, network printers, and other equipment is back to being fast. Score one for Linksys, not.

Best practices for resolving nmsrvc issues

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