W2K3 DNS Forward Lookup Zone confusion

    Kevin was helping me on a related issue and it may be coming into focus for
    me but is still a bit hazy. I created DNS as per directions on a new W2K3 AD
    and looked and compared to a working, existing W2K AD. Kevin made some
    suggestions and I followed but get an nslookup error (started as a Timeout
    but changed to Non-existent domain after a Reverse lookup Zone creation).
    This, to me, indicates a Forward LZ problem. As I said, I compared to W2K
    and there is a significant difference I wrote off to differences between W2K
    and 3 but maybe not. There is a Forward LZ named (_msdcs.mydomain.com) that
    does not exist in the W2K DNS. The correct one also exists (mydomain.com).
    Is this my problem?

    Let me be sure I am making myself clear on other points too. Kevin's advice
    has been good and helped quite a bit and I simply may be missing something
    simple. But to further explain, I am getting perfect nslookup results from
    the PDC. The errors are happening on the Secondary and the one client I have
    setup to test. Everything else seems to be fine. Netdiag and DCdiag run on
    Secondary all pass. No Event errors...the logs are very clean. Forced
    replications take place cleanly, etc.

    The PTR record appears to be correct, the LZ show the correct first three
    octets and then ".x Subnet" with a folder underneath with the last octet as
    is name and the right pane content says (same as parent folder) Pointer
    (PTR) and then the correct FQDN of the server. Properties shows the IP in
    reverse order with the expected ".in-addr.arpa" entry and the Host name box
    has the correct FQDN also.

  3. In
    (same as parent folder) would not be correct for the PTR record, the PTR
    record should be the IP number of the DNS server. e.g. if the DNS IP address
    is 192.168.0.2 and the reverse subnet is 192.168.0.x the PTR should have IP
    number 2 with the FQDN of the DNS server. If you switch to advanced view,
    the reverse lookup zone would be 0.168.192.in-addr.arpa which when included
    with the IP number 2 would give a reverse lookup for
    2.0.168.192.in-addr.arpa.
    It is possible to have a (same as parent folder) PTR record for this IP but
    the zone name would have be 2.0.168.192.in-addr.arpa.

    I deleted and retried the creation of the PTR but it does the same thing
    each time. I create it just as you say, entering the last octet of the IP
    number and the Host name. It all appears as you say. I then hit refresh and
    the icon that appears to be the record changes to a folder with the Same as
    Parent in it's contents in the right pane and Same as parent folder in the
    Host IP number box under properties. This happens each time I create it. The
    FQDN is as you state..IP in reverse order. The zone name is the IP in
    correct order with the .in-addr.arpa extension. I can send you a screen shot
    if you like.

    There is the problem, in Advanced view the zone name should be
    0.168.192.in-addr.arpa. for a 192.168.0.x IP address scheme.

    So in creating the Zone when it asks for network ID I should enter the
    reverse IP as in 0.168.192?

    I should mention that the dialog box says to enter it in it's normal (not
    reversed) order which is what I did originally.

    I used the Reverse Lookup Zone name instead of the Network ID box and the
    reverse setting is now in place as well as the pointer. This was done on the
    PDC and it seems correct. When I forced replication the zone is named in the
    forward IP order on the Secondary DC box. Interesting.

    You only get to see the zone name, 0.168.192.in-addr.arpa., if you have the
    console in Advanced view, in normal view you'll see the subnet ID e.g
    192.168.0.x Subnet.
    Advanced view also lets you see the Cached lookups in DNS and the
    Auto-created reverse zones; 0.in-addr.arpa., 127.in-addr.arpa., and
    255.in-addr.arpa.
