Specific configuration for Windows NT 3.51

Enabling for UM-Client the use of UDP port 162 :

If UM-Client is started after the Windows NT SNMP Service, UM-Client cannot use port UDP 162 (snmp-trap) because the SNMP Service is already using it (with the SNMPTRAP.EXE executable).
To prevent this happening, you must replace the SNMPTRAP.EXE executable file, in the system directory (generally \WINNT35\SYSTEM32) with the SNMPTRAP.EXE executable located in the UM-Client installation directory.

Do not forget to back up the original SNMPTRAP.EXE file before replacing it, in case you should wish to restore the system to its initial state.

Procedural detail:

• If SNMP Service is running (you can check this using the Services Control Panel) , you should proceed as follows:
  - disable automatic starting of SNMP Service (using the Services Control Panel)
  - reboot your system.
  WARNING: stopping SNMP Service does not stop SNMPTRAP.EXE; this is why you must reboot the system.
• move to the Windows NT system directory, by entering:
  cd /d C:\WINNT35\SYSTEM32
• back up the SNMPTRAP.EXE file, by entering:
  copy SNMPTRAP.EXE SNMPTRAP.BAK
• copy the SNMPTRAP.EXE file located in the UM-Client installation directory to the system directory, by entering:
  copy C:\UPSMAN\UMCLIENT\SNMPTRAP.EXE
• start SNMP Service and UM-Client and enable automatic starting of SNMP Service, as required.
