WinServer2012R2 - Print server role - LPD service active
I can apply changes to the configured printport tcp/ip settings (default 515) to 516 (regedit or script).
I can open the port after changes have been applied but after 10-15 seconds this Raw Setting Port Number is reset to 515.
This behavior is not consitent because on some printports the changes are kept in the system.
What do I overlook?
