Hi all,
Am running exchange 5.5 on NT4 on domain1.
Running AD on win 2k server in domain2.
Running DNS service on win 2k3 (web)server in domain2.
-- DNS requests are all done through firewall.
- primary DNS server is the 2k3 (web)server (above)
- secondary DNS servers are those of out ISP
Trust between domain1 and domain2.
Mixture of client outlook versions, predominately though we are running Office (Outlook) 2003. No problems whatsoever.
- We use cached mode.
To rule out DNS as a culprit, i would ping the mail server from the command prompt of one of the workstations.
ie.
c:>> ping mailserver
Where mailserver is the name of your mailserver.
This should resolve the IP address, send 4 packets and receive them just dandy. If it doesen't I would look at DNS config.
c:>> ipconfig /all
will tell you what you need to know about your current configuration.
Either put the servername IP address in the (lm)hosts file of every workstation as suggested above, or enable DNS service on one of your servers and point your DNS search records to that server. Or put the IP address of the mailserver into the mailbox profile when you set it up for a new user.
Cheers.
