Which version? Whenever you ask for a problem, tell the authors exactly which version you are using.

That is strange.

What means kick off? How do they exit?

And this only happens once you start up a session with nxclient?

You're messages and nxserver logs can't be empty, please read the FAQ on troubleshooting to at least get the logs. Also get the and post the client logs.

Given the global nature of the problem, I however doubt that NX has anything to do with it.

Try the following:

- Create a new user "b" additionally to your user "a" on 'remote'
- Let "b" login into the machine 'remote' from:

* the same machine you login to 'remote' via nxclient
* another machine, where you have a screen running to login into 'remote'

If your nxclient also throws out user 'b' then you have a serious security issue (not your fault though) as no user should be able to kill off the session of another user.

Best regards,
