I have a local domain with DC win2003 and an exchange server also added to the domain. When I connect a pc to the domain and put the ip , mask and DNS (the same as DC), outlook dont get directly the users credentials to log him in. I manage to resolve it adding a default gateway to NIC's the ip of the exchange server.
This approach is wrong and I have to face it now that I really need a default gateway to an other network. What do I do wrong? With my little experience I believe is the DNS server fault. Thank you for your help in advance.
