OWA default login

[ethos]

Hi guys,

Trying set up OWA for work, got most of the way but trying to get rid of the need for "domain\username".

I've tried adding "\" "domain" "domain.local" "servername.domain.local" to IIS and system manager (obviously testing one at a time)... but it's still prompting for a **** domain!

Any ideas chaps?

Thanks
