VPN Clients Fail to Register in DNS

We have a Wireless network which is configured to block all outbound traffic
except VPN traffic for security purposes. Wireless users must connect to
our VPN server to gain any type of "outside the sandbox" network
connectivity. When clients connect, many times they fail to Register their
addresses in DNS. this prevents LAN clients from getting to \\VPNClient.

I have set the VPN client to automatically register its address in DNS...
But when I look at the DNS server they are not there... most of the time.

Where should I look? Can RRAS automatically register the addresses it hands
out?

Thanks!

RRAS cannot register the addresses it hands out - it has no mechanism to do
that. Either the client must do it or a DHCP server can do it on behalf of a
client but that's it.

Try this test. On the next problem client which fails to register it's
address, execute an ipconfig /registerdns command and report back what
happens. Could be a timing issue.

Let me give more network info.

We are class B. I am responsible for a specific sub domain say
mysub.company.com. My sub has its own DNS server which is 2003 and runs
RRAS , file shareing, and is a DC. It has 192.168.130.253 and
192.168.130.246 as addresses on a single NIC. Vpn.mysub.company.com points
at 246 and servername.mysub.company.com points at 253

Company
192.168.X.x

Wireless Clients
IP = 192.168.184.x
Dns = 192.168.4.4

Mysub.company.com
ip = 192.168.130.x
Dns = 130.160.130.253

I took my laptop off a LAN connection and connected only via wireless. I ran
a ipconfig /registerDNS and my A record for my laptop VPN did not update to
the address of the VPN adapter... Looking in DNS, it stayed at the address of
my LAN card. I tried several times with no luck

I tried again several hours later to ipconfig/registeDNS and this time it
updated my record.

NSLookup returns the address of our main company DNS... not the DNS that i
manage and that my clients should register with.

RRAS is configured to get IP from DHCP.... LAN DHCP auto registers in DNS...
why not the RRAS DHCP clients?

Where should I look from here?
