We found that the pisdk version on our production server, was a older version then on our development server. So we uninstalled pisdk on the development server and installed the previous version. Now pisdk on the developmnet server think it is on a Openvms platform (i.e. giving us port 545 when we try to use connection manager, instead of 5450). Has anyone come across this before and if so how do you sort it out.
