This is Toshiba's config free utility and have on my 1 yr old's cool
NDSTray.exe could not be run while starting my laptop
It's from Toshiba and It came with my laptop. It is really helpful.
perfectly fine for toshiba laptops. it is for network control
it's fine. not a big memory hog, and very useful if you take your laptop around to lots of different locations and switch between networks (wired and wireless)

that it failed and my comp crashed
NDSTray.exe is a harmless, basic tool that is installed by Toshiba. It is useful for easily switching wireless networks if you travel with your laptop a lot.
AVG 8.5 Free Edition identifies this as "Trojan horse Generic14.BUL" with virus DB 270.13.14/2238
I would like to disable NDStray because it will go through half hour bouts of hogging 50 to 60 % of my cpu and makes things glitchy.
cpu hog removing it sped up the pc significantly.
it uses 100% of cpu and never seems to stop. I have to stop it!

All the stuff about harmless is a lie. It can be a virus and it takes up more than 50% of my cpu usage
This thing in a massive memory hog. It will just randomly use 100% of your cpu and half your ram for no reson every couple of weeks, and wont stop until u restart the computer or end the process. While it does this, everything else freezes, u cant save documents, games crash, and if ur in the middle of a download, forget it its gone. and in some cases if u had too much going before it decided to hog the memory, your computer will crash. This thing is very bad for your computer, but essential cause the wireless card wont work right without it.
It hogs more than half of my CPU. I can't even load a page. Remove it.
Real resource hog
There IS a legit program called NDSTray.exe, however if you are not on a Toshiba, you shouldnt have it on your computer. If you ARE on a Toshiba then you will have to look further into the program to determine whether or not it is legit or a virus.
not much - is hogging my cpu!!!
Regularly uses over 50% CPU - also a memory hog - very poor
  Bill Hewitt  
Right now was taking up 50% and more of my CPU for a long time!!! Making my computer slow! I killed it from task manager.
It is used to switch between from using a modem to using free Wi-Fi for Toshiba computers only
  David Leggett   (further information)
uses 100% resources and I have a toshiba.

Best practices for resolving ndstray issues

A clean and tidy computer is the key requirement for avoiding problems with ndstray. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ndstray.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
