name resolution of RAS clients hostname

[Saah]

Hi,

I run into a problem trying to set up a failover remote access for distant
computers.
The thing is our application is based on MS Message Queue 3.0 and uses OS
(hostname) addressing for messages (both directions).
So - once the clients connect via dial-up PPP connections - I need them to
update their A&PTR records in the given DNS zone.
The clients are members of different AD domains than the RAS server is.

I read the docs and decided to make RAS allocate IPs from the DHCP pool
(made for RAS only) so the DHCP could update the A&PTR records in the DNS
zone on behalf of the clients.
I added DNS address & suffix in the DHCP option for the pool (i.e.
DNS=172.16.0.2, suffix=ppp.mydomain.com).
I configured RAS to use DHCP as the source of IP configuration (i.e. DHCP
server=172.16.0.2).
I configured the clients to register their IPs in the DNS, using interface
specific name+suffix (i.e. 2 checkboxes in the DNS pane).
I allowed unsecured updates in the DNS zone, to make it accessible for
computers from out the AD domain.

Situation:
Clients receive simple configuration while connecting.
After about 15 seconds it is replaced by the DHCP options (DNS IP & domain
suffix).
The problem is - the zone remains empty.
The clients do not create/update their A&PTR records, so they are not
available for the MS MQ to send them messages.

My configuration:
2 nodes
MS Windows Server 2003 EE
MS MQ (clustered)
RRAS (node2)
DHCP (node2)
DNS (node2)

1. Is it possible to use DNS based name resolution for dial-up clients to
make hostname-based comunication possible?
2. How to make RRAS or DHCP or the client itself to register A&PTR?

Please help. Thanks in advance.

The problem lied in MS Windows XP SP2.
