Upgraded an installation of a Ex2000 SP3 on a Win2000SP4 DC. The upgrade went
fine apart from alerting on c:\winnt\system32\dapi.dll which was older than
the current installed version. I did not overwrite the newer version. Also
MSSearch files had the same issue with old vs new.
Howerver, once Ex2003 was installed, the server was unable to resolve
hostnames in its own domain. Just using single hostname fails, but using the
entire FQDN works.
It looks like windows no longer adds the domain suffix according to what's
set on the TCP/IP parameters (DNS suffix for this connection). When I set
"Append these dns suffixes in order" it works for a short while, and then
fails to resolve non FQDN after approx 30 min.
This same issue also occured on our OWA server when upgrading for Ex2000SP3
to Ex2003, which was on a plain Win2000 SP4 server.
I've googled and looked around to find someone with the same issue, but so
far I've found nothing. Anybody seen this issue before and have any good
suggestions on how to fix it? Temporary fix so far has been to add all
required hosts to the local hosts file on the server.
