Host Does Not Exist Error While Host is there...

Hi,
Am getting a random host does not exists error while host is there... any thoughts? Am not sure why sometimes it runs with no issue and at times it fails with the error message.

Is there a way to silence the running of the script? It opens a black pop-up window even if I took out the /console on the script.

Attached is the error and code.

Any help is appreciated.

Please post session log files for:

• Scripting session that randomly works
  
• Scripting session that randomly does not work
  
• GUI session

Ntb, we generally do not recommend relying on GUI configurating in scripting:
