When trying to create a Sotware Package Distribution to include the zsm7sp1ir3a_polydist.cpk file I've got the following error:

Unable to perform the remote call. Make sure the remote server has ZENworks Server Management running properly.

The Distributor has NW 6.5 sp6 with ZENworks Server Management 7 sp1 running properly which is using almost every day.

How to resolve this in order to install zsm7sp1ir3a_polydist.cpk distribution?
