Yes, this all is familiar, but not exactly what I found in practice. The
RRAS server has two cards, one on the local net and one on the internet/dmz.
Each interface of course is statically assigned, with the proper dns, wins,
default gateway. On the client end from what I recall (and I'll verify this
once again when no one's around), the proper inheritance was not getting
passed from rras - the client I tested was keeping their defaults.
I had set the static address pool, and "Use the following adapter to obtain
dhcp, wins, dns..."
set to our LAN/Intranet adapter.

Oh, was that your question. The information that the RRAS clients are
getting.
The following comes from the Help function on the Windows 2000 server and
explains that most option information (wins server, dns server) comes from
the configuration on the Routing and Remote Access server and not the DHCP
server (I think even if it is running on the same machine).
When a Routing and Remote Access server assigns an IP address to one of its
clients, either from its own static address pool or from its cached DHCP
address pool, there is no effective lease time for the IP address, since it
is released when the client disconnects. However, remote access clients can
still receive additional TCP/IP configuration information from the Routing
and Remote Access server. For example, WINS and DNS server assignments can
be delegated to the client when it connects. Again, this information is not
taken from the options given in the DHCP lease. Instead, these are taken
directly from the Routing and Remote Access server settings. If a Routing
and Remote Access server has WINS or DNS servers as configured entries in
its dial-up connection properties, these settings are passed on to its
clients. The following table lists the options that Windows-based DHCP
clients support and how each of these options has its values assigned to
clients that use DHCP through connection to the Routing and Remote Access
server:
Option
Description
IP address
The Routing and Remote Access server proactively obtains IP addresses from
the DHCP server and builds a cached pool of DHCP leased addresses. It then
distributes these cached IP addresses upon demand to dial-up clients and
manages each lease accordingly. This is the only information from the DHCP
server that the Routing and Remote Access client receives.
WINS server
Values provided with this option are taken from the dial-up connection
properties of the Routing and Remote Access server if it is configured with
WINS server addresses. The client acquires the list of WINS servers that are
configured on the Routing and Remote Access server.
DNS server
Values provided with this option are taken from the dial-up connection
properties of the Routing and Remote Access server if it is configured with
DNS server addresses. The client acquires the first DNS server address
listed in the search list.
Subnet mask
The subnet mask corresponds to the default subnet mask associated with the
standard address class type (Class A, Class B, or Class C) of the given IP
address.
NetBIOS scope ID
NetBIOS scope ID information is not passed to the client. If you need to
modify this setting, you must change it directly on the client.
Node type
Node type is not taken from the DHCP lease but can change on the Routing and
Remote Access client, depending upon WINS information. If the Routing and
Remote Access server has no locally defined WINS servers, a b-node Routing
and Remote Access client remains a b-node client. If the Routing and Remote
Access server has locally defined WINS servers, a b-node Routing and Remote
Access client switches to h-node for the duration of the connection.

From my experience using a similar setup (which was not extensive... exactly
ONCE) the additional information came from the network settings of the RRAS
server. It allocated IP's based on the range that you give it, but it hands
out whatever information it knows for the DNS/WINS entries.
Does the RRAS server have these items defined?

Subject: [windows2000] RRAS as a router
We currently have our RAS server (Windows 2000) on the same network as one
of our main floors, with the rest of the server farm. It's using DHCP, so
it's of course assigning addresses on that network.
I've tried making it route, but unless I'm really missing something there
was no place to assign anything beside the address & mask - so the wins,
dns, default router etc. are not getting forwarded to the clients. So they
get an address, but can't do much beyond that.
Before I attempt this again, can some of you maybe clue me in on what I'm
overlooking?
