I'm trying to distribute applications across our sites using 'Application
Site List' under fault tolerance until I have TED configured.

Has anyone used this method of distribution successfully before? There
seems to be little documentation on how ZENWorks figures which
server is closest to the user and could do with a little help!

We have four sites in our tree, each with their own ZEN server, linked by
2meg MPLS which we'd rather not be distributing applications over!
