OK I think I have a DNS issue.
I have multiple servers in the main office and everything works fine, one of which is primary DNS server (ServerA) and one is the Exchange Server (ServerB)
I have another SBS in another domain that is a DNS Server for the remote location (ServerC) with a secondary DNS record of ServerA
My problem is that 2 XP workstations in the remote location will not connect to exchange using outlook if the DNS record is automatic or if statically configured to ServerC. The user can connect to ServerA with VPN and exchange connects however this is not desirable. If DNS is configured as ServerA then Exchange also connects however this causes other issues (scanning, etc cannot connect to the workstation using ip address)
Other workstations seem to be OK and configured without Exchange Proxy HTTP connection except for these 2 machines running XP (either way this does not work either).
On serverC DNS records all hostnames match IP addresses
Please help if you can assist I cannot get the Exchange working with the DNS server they should be using, any ideas of what else to try, check? I have tried all outlook settings and duplicated settings from other working machines as well?
