Think that I normally live in Copenhagen but next day I might be in Beijing or San Diego, you really want to use the closer server and in some cases there are strict rules, maybe even laws about it (not sure which). For Exchange, the point is obviously that your mail and calendar comes from the same repository wherever you are but outgoing mail and other services may be more locally anchored.

No, I don't think DHCP was involved and it did not work as painless as
it should have. I was thinking that DHCP might provide an address to a
portal or such that might do the actual work. A bit like the "next
server" for TFTP.
