Alright, here are my questions. I have collected more than one email here. 1st of I all it is hard to tell my customers that they are not able to connect to that site because this is not a legal host name. Since all other ISPs are fine with it. I did not understand why other Unix OSes like Solaris or OSF1 support it. I also believe that there could be a more meaningful error message else than the one I got "Unknown server error". "Jordan K.

Well I think it cant be the problem when my name servers are using FreeBSD operating system and my Solaris box is instructed to use them for domain name lookups, why do Solaris work then if this is a problem with name server?
