I have finally gotten the DDNS working at one location. However, for my
remote sites, DDNS is not working.

Here's my setup:

District Office has 2 servers: F01 running DHCP, G01 running DNS. Both
servers are on the same network.

High school has 1 server HS01 with 9 VLANs. HS01 is also running DHCP.


DHCP is working at the high school, but the workstations are not being
registered in DNS.

I have created a primary IN-AADR.ARPA zone - 10.IN-ADDR.ARPA and set the
G01 server as the authoritative DNS server.

Also, I have a zone named AND4 that is also primary zone. The G01 is the
authoritative DNS server for this zone.

In the DHCP setup, the F01 server has 10.70.0.0 subnet with the DNS zone for
Dynamic update set to AND4 - default DHCP server is set to F01. The
addressing range type is set to Dynamic BOOTP and DHCP with the DNS Update
Option set to Always Update.

For the high school, I have 9 different subnets - one for each VLAN,
10.72.100.0, 10.72.101.0, etc. For each subnet I have the DNS Zone for
Dynamic Update set to AND4. The default DHCP server is set to H01. The
addressing range is set to Dynamic BOOTP and DHCP with the DNS Update Option
set to Always Update.

I also have 4 other sites without VLANs that are not updating DNS records.
Is there some router setup or other setup I'm missing? Is this type of
setup supported? I have one DNS server for 6 locations. Each location has
their own DHCP server.

Thanks for the help,

Scott
