Introduction:

In rare situations, the NX.env file may become unreadable after SDM/CMDB configuration, even though the application runs fine.

If you open the file in notepad or wordpad, you will see some Asian characters in the file. This technical doc provides a way to restore the file.

Instructions:
  1. Open the NX.env_nt.tpl file in the <Service Desk Manager installation directory>\pdmconf\ folder and save it as ANSI format.
     
  2. Next, rename the NX.env file in the in the <Service Desk Manager installation directory> folder to backup_NX.txt.
     
  3. Run pdm_configure as the system administrator and after that the NX.env file should be restored.
