We have 5 Servers running NW6,5 sp5 and Zenworks 7. I attempted to
install ZFD 7 sp1 hp5 on these servers. Two failed installation at the
point where you "select servers", giving the message that the Zen7
installation was not recognized on these servers, and that this may be due
to insufficient rights. I have logged in as both tree admin, and
container admin and verified that I have all rights in both cases The
other three installations completed and run normally.

I reinstalled Zen7 on one of these servers (completed normally), then
tried to apply the Service Pack with the same result. Any ideas?
