On a new domain with Exchange 2003 SP2 I am having the problem that every time a user needs to access email via POP or HTTP they must type the username in the form of: domain\user or user@domain. In every other setup I've ever done I've never seen this. We would much rather prefer to just type the uesrname as everyone is used to. Why could it be requiring the extended logon credentials and how do we stop it?
I have also just recently realized that this is true for POP and HTTP via IE 6 & 7 on dozens of machines, however oddly enough this problem does not affect Firefox browsers which access webmail with username alone?????
