Hi Experts,I had in my test network an 2k3 R2 64 bit Exchange 2007 Server, this was also DC ( I know, that was dumb)anyway the RAID 1 failed and left me without Exchange. I had a Longhorn Server 64 bit test machine setup and (after much AD cleanup ) was able to intall Ex 2007 on it, after several attempts and configurations Exchange Installed without a hitch, my problem now though, is none of my cllents can connect to the Exchange server, I can ping the server with the IP and the FQDN but not the NetBios name,I should probably mention the Old X-server was also a DNS server, the Longhorn install is not a DC nor a DNS and the X-install is SP1... I am running out of options and at my wits end, Any direction from here will be GREATLY appreciated. thanks
