We are reorganizing our server structure at our company. We have 2 new servers. One will be the primary domain controller for the company and the other will be used exclusivly for email (exchange server 5.5). Originally we had been logging onto the email server and setting up trust relationship to the other server so users could access their files. Now we want to have the primary server authenticate logons and be able to access email on the email server. I am having a problem setting this up in a test environment. We can log on to the primary server but I keep getting the message that I do not have permission to access my mail box on the email server. I set up a one way trust. with the primary server "trusting" the email server and the primary server "trusted" on the email server. Is this correct and is there anything else I need to do? X-)
