I have 2 NT 4 domains, both on the same IP segments each domain has a PDC and 3 BDC's all netbios name resolution and sharing, network browsing is working fine. Both domains trust each other so it is a 2 way, I can log onto domain A and map drives to Domain B with no problem. I have a question about Outlook clients /authentication... Can users log into /authenticate onto domain A, and then open up a mail box that is homed on another domain, with an exchange server??? when I try this it says that you cannot open up the mailbox would you like to open up your defaults??? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
