Michael,
thanks for the reply.

My issues stem from taking my MacBook and its server from home to work and I find it extremely frustrating that NUDC on my secretary's PC can find the server on my MacBook but NUDC on the same MacBook cannot.

No-one from Now seems to be addressing the issue and manually changing the IP address each time I go from home to work (after re-setting up the server so its not a bonjour server) seems a bit excessive to me.

Roll on Nighthawk!

Cheers
Iain
