Hey all...Was hoping someone could give me some insight in this...This isnt a sole exchange issue as it affects my overall default website - but I figured someone might be able to give me some ideas of where to start I run a SBS 2003 server here at home just for my family to colaborate - it is using a .local domain but is setup for routing and therefor is hooked directly to the firewall embedded router. I do have a domain pointing directly to it using using a dynamic dns service to be able to access OWA and whatnot and it is working perfectly...in this respect I couldnt be happier. Unfortunately we do have a single powermac running tiger...what a pain it was just getting Entourage working with the Exchange. Mac's apparently have issues with the .local domain conflicting with DNS as it doesnt see it as an actual domain - I did fix this setting the dns for it statically. The issue I am having has to do with the CA Cert since it is setup for the .net domain Because the Mac is trying to sync up with exchange using the .local domain, it errors when it tries to validate the cert initially. It will sync up with exchange as soon as I click okay, but I'm wondering if anyone has found a way around this? I dont suppose its possible to install a 2nd cert (one for .local?) Outside it works fine as I did install the cert to the keychain, but it is frustrating having to click 2-3 times just to get exchange to pop up. Thanks in advance, Devin
