The problem

SP3 server will accept

iprntcmd http://serverdns.co.uk/ipp/printername or
iprntcmd http://xx.xx.xx.xx/ipp/printername

Server that has been patched to SP4 will only accept

iprntcmd http://xx.xx.xx.xx/ipp/printername

I would rather use the DNS name rather than an IP. Anyone got any ideas as
to what has changed between service packs to cause this

Any help appreciated
