Error-601 on multicast image

hi
i used to use the multicast option on console one to send an image to
my computers over the network but lately i couldn't do that coz i get
this message:

(Error-601) The object entered could not be found in the context
specified. Refer to help .........
Some relationships between the added or deleted objects and this object
may not have been set up correctly and will have to be done manually.

details: i just right click on the netware server (6.5) and then choose
properties then zenworks imaging and when i press Add and write a name
for the image i get the message above. i go to Nwadmin32 and lookup
there and i find the name that i just wrote as a security icon. so what
is the problem can anyone help.
thanx in advance.
