Subject: Traveler platforms

Hello - sorry for any confusion - Traveler should work on any Windows platform that Domino works.

Subject: Traveler works with W2k3

Hi,

Sorry if it’s not really an answer to your question.

I’ve just installed a traveler server on a W2K3 platform and it works properly.
