WLAn clients unable to reach subnet handled by W3K server

[Guest]

Hi!

I encounter a connection problem between WLAN clients and one of the subnets
managed by my W3K server.

The ASCII diagram looks awful here in the newsgroup, that's why I will try
to explain my network configuration verbally:

Internet --> Cable Modem (84.65.233.1) --> WLAN ROUTER (DHCP Server) (WAN
84.65.233.2 / LAN 192.168.168.1) --> W3K Server (Network card 1:
192.168.168.2 / Card 2: 192.168.100.1)

The W3K server (acting as DNS and DHCP server for subnet 192.168.100.0) is
connected to 2 WINXP file servers (192.168.100.2 + 192.168.100.3),
LAN-Routing is activated and works betweend W3K server and file servers

Since the WLAN Router too is a DHCP server for the net 192.168.168.0, all
WLAN client receive (correctly IP addresses between 192.168.168.3 - 32). Note
that the W3K server is in this same net (192.168.168.2)

Now the problem:

o) I am able to ping EVERYTHING from the W3K Server (the file servers
192.168.100.x, the WLAN Router, the internet AND the WLAN clients)

o) I am able to ping EVERYTHING from the file servers (the W3K server, the
WLAN router AND the WLAN clients)

o) BUT... the WLAN clients, which can reach the internet and which are able
to ping the W3K server 1st network device 192.168.168.2 are unable to ping
any of the file servers in the subnet 192.168.100.0

I tried to add a static route in the WLAN router which says: Destination
address 192.168.100.0 should be routed to the W3K server's IP 192.168.168.2,
thinking that it's maybe the WLAN router that doesn't know how to forward
request to subnet 192.168.100.0 - but nothing changed!

What do I have to do? Do I have to configure the W3K server in a certain
way?! Or is the network configuration I want to build impossible, if I want
WLAN clients to access the subnet 192.168.100.0 which is managed by the W3K
server?!


Thank you in advance for hints or even solutions!

What are the gateway IP's of each nic?
It looks like you are trying to use your w2k3 machine as a router, but did
you setup the server to act as a router through routing and remote access?
Please post the Ipconfig from each NIC, and post what the gateway of the
192.168.100.x router looks like if any.

Yes, the W3K Server is also acting as a router!
In my opinion routing and remote acces have been correctly installed and
configured on the server - after all, I am able to reach the internet from a
client in the 192.168.100.x subnet as well as reaching this client if pinging
it from the W3K server!

The W3K server has 2 network cards, 192.168.168.2 which is connected to the
WLAN router and the other one 192.168.100.1 which is connected to the subnet
in question. As for the gateway for 192.168.100.x subnet, 192.168.168.2 has
been assigned. When I come home I will do a IPCONFIG for the two cards and
post the result here...

For some reason the WLAN clients that are connected to the WLAN router
192.168.168.1 are not able to ping the subnet 192.168.100.x, but they CAN
ping the 192.168.168.2 card of the W3K server...
