sorry i wouldn't say mac doesn't use them it merely uses the dns info provided by the dhcp server. so it does use them but in a slightly different way. I should of explained that better!!! My dns boxes were blank but i did a wee bit of pinging and found out one dns that way!!! Just didn't think i'd need both. I will have to ring my service provider and obtain the second one!
Thanx so for help-i'll let you know how it goes!
ps anything else you might think it is if it turns out not to be that???
