We have 3 domains. DOMAIN1.COM, DOMAIN2.COM, DOMAIN3.COM. Domain's 1 and 2 are Active Directory domains each running DNS for their domain. DOMAIN3 is a domain with only an Exchange server named EXCHANGESRV. On the DNS servers in DOMAIN1 & DOMAIN2 I added a host record for EXCHANGESRV. When a client in DOMAIN1 tries to ping EXCHANGESRV it resolves to EXCHANGESRV.DOMAIN1.COM and can ping the server. For clients with static addresses (including DNS) who do not login to any domain try to ping EXCHANGESRV it fails and cannot find host. However, if their DNS server is in DOMAIN1.COM they can sucessfully ping EXCHANGESRV.DOMAIN1.COM. In Outlook where the server name is specified as the NETBIOS name EXCHANGESRV clients cannot login because it can't resolve EXCHANGESRV.
Some of these static clients are Mac's and some are PC's. Is there a way to have them all resolve EXCHANGESRV without setting them for DHCP as they are on a different subnet and there is no DHCP server available.
