Networks

Hi,
I have a NT (sigh!) domain and 2 w2ksrv set up as print servers.
My will is to set up them identically for failover: once the first
goes down, changing the ip in wins table, I'd like to redirect the
print trafic to the second. And so far no prob, I created the same
spools with the same names in both the servers.
The prob is that when I switch, it says "not allowed". I know that
there is a known problem making this in 2003 (pointing a dns record
with a name different from the server one)...is this the case? Or
else, how can I do?
