Hi All,

I am preparing for installation of Exchange2007 so I have been checking my
DNS Settings etc. I can ping my DNS Server (aa1) from this server (aa2)
without problem using both IP address & host name, but when I try to ping the
new Server (aa2) from aa1 or any other client, it just times out.

I ran nslookup and typed the following: nslookup aa2.aa.co.uk

The results confirmed that the correct DNS server & IP address were
configured, but showed the aa2 IP address as being xxx.xx.xx.38 when it
should show xxx.xx.xx.6 - this is configured in DHCP as a reserved IP, and
then later directly on the NIC itself.

I have tried ipconfig /flushdns on the DNS Server without any success. I
have also checked for duplicate entries, of which there are none relevant to
either xxx.xx.xx.6 or xxx.xx.xx.38

Can someone please put me out of my misery!!

I have been tinkering around with my DNS server and noticed that there was a
record which had aa2 as xxx.xx.xx.38 - this was in the forward lookup zone. I
edited it to xxx.xx.xx.6 and ticked the "amend PTR" box and it now seems to
be working.

When using nslookup I now get xxx.xx.xx.6 as aa2's IP address. I have tried
this on 2 clients and I get the same results, however when I try to ping aa2
from aa1 using the hostname, it attempts to use the xxx.xx.xx.38 IP address.
I have checked by using nslookup from aa1 and it tells me that aa2 has the IP
xxx.xx.xx.6 ?!

Can anyone clarify this? Is it safe for me to delete all records of aa2 and
xxx.xx.xx.38 from the DNS forward lookup zones, then restart aa2 on the
presumption the records will be recreated - without any of the problems??

I am really close to a solution so any advice accepted !!!
