# Why isn't nsupdate working from my Windows machine?

### Question:

I'm trying to run `nsupdate` on my Windows machine using a text file as input, but it's not working. The same updates are working OK from a Linux client.

### Answer:

It's most likely that the **send** command in your text file isn't being recognized. Check for the **end of line** character following it in your text file. Most UNIX editors automatically add this, but many Windows editors don't.
