Hi All,

We currently have one DNS/DHCP server running on Linux. This has always
been of concern, if it were to fail, so we have decided to use the
DNS/DHCP that Netware supplies, running both DNS/DHCP on both our
netware servers. We have followed the directions for Creating the
redundency we require.

Both DNS setups forward any unresolved queries to our exsisting DNS
server then on to our ISP's DNS. This was done so that as the DHCP gives
out the new DNS servers, older infomation is still avaliable. I noticed
after exporting the setup that things were not as expected.

******* Exported output **********

The lines:

$ORIGIN plc.uk.
graphic IN NS main.graphic.plc.uk.
IN NS comms.graphic.plc.uk.
IN MX 10 comms.graphic.plc.uk.

confuse me. The appear to create a 'plc.uk' zone.

This is further supported when I do an NSLookUp.

*****************************

When using the new DNS server incorrect results are returned, but when I
changed to the old server all appears as expected.

Is this how things should be? If not what have I got wrong? Is the there
a hole in my understanding (very likely)?

Netware 5.0
