Question : Exchange Server 2003 setup - DNS failed test in NetDiag.log

Hello - this question concerns a small office setup with 8 Windows XP Pro computers and a single server running Windows Server 2003, Standard edition, SP2 which is also the DC.  

I am working my way through the Exchange Server 2003 installation checklist and have run into an issue after running the NetDiag.exe command.  All looks good except the DNS test which comes back with the following error:

DNS test . . . . . . . . . . . . . : Failed
    [WARNING] The DNS entries for this DC are not registered correctly on DNS server 'xxx.xxx.x.xxx'. Please wait for 30 minutes for DNS server replication.
    [WARNING] The DNS entries for this DC are not registered correctly on DNS server 'xx.xx.xx.xx'. Please wait for 30 minutes for DNS server replication.
    [FATAL] No DNS servers have the DNS records for this DC registered.

One issue I've found so far is that there is no Reverse Lookup Zone set in DNS on this server and there is no "_msdcs.domainname.local" listing on the Forward Lookup Zone.  

Am guessing both of those issues need to be rectified but before I do that would like some expert opinions on DNS resolution.

Or, can I simply proceed with the Exchange Server 2003 installation and not worry about this - or am thinking this problem may bomb out my Exchange install....

Many thanks in advance for your help.

You can delete it, although its presence shouldn't affect the other zones.  What do your two new zones look like now?  Do they have any records and/or folders in them at all?  Also, does "ipconfig /all" show the correct primary DNS suffix for the DC?
