Existing Server OES on (SLES11) - Single Server
trying to add a second server OES on SLES11 SP1 to existing tree

I'm getting a error
no refferals
Nsdconfig returmed value 78

I'm assuming its possible to add a SP1 server to the existing non sp1 & and
if I can't the Installer will tell me.

I've tried several times - re-entered info correctly

What I'm I doing wrong?
