Here is my configuration:

I bought a 3620 router to help me study for my ccna.
I have a cable modem. It is connected to a d-link broadband wireless router
I have set up basic rip on the 3620.
Networks 192.168.0.0 and 192.168.1.0 are specified after router rip
All networks are /24

I have asigned 192.168.0.2 on interface e0/0
- this goes to the cable router. It's internal IP is 192.168.0.1
- the cable modem has dhcp set up
- I have a Windows 2003 server, DNS/WINS on this subnet. 192.168.0.101
- The server is A/D, hosting the Test.local domain
- There is a switch between the server, 3620, and the cable router
I have asigned 192.168.1.1 on interface e0/10
- this goes to workstation, 192.168.1.2
- the workstation is a member of the Test.local domain
- it can not login with the router in place.
- there is a switch between the workstation and the 3620

Here is my problem:
1) From the second pc, I can not ping the cable router
2) From the server, I can not ping the workstation
3) From the Router I can ping the cable router
4) From the Router I can ping the workstation

show ip route:
C 192.168.0.0/24 directly...
C 192.168.1.0/24 directly ....


My conclusions:
There is a DNS error somehow, but I have a DNS/WINS server running.
Without the 3620, my workstation points to the DNS server successfully
For it's WINS/DNS needs, and everything, including Internet searches, works.
Is there a way to specify my dns/wins server for the cisco router?

> Here is my problem:
> 1) From the second pc, I can not ping the cable router

Because the cable router (D-Link) is probably nto set up to run RIP.

> 2) From the server, I can not ping the workstation

Because the default route of the serevr points to the D-Link which has not
route to the 192.168.1.1 network. Does the server run RIP? Either get the
Windows server running RIP or add a route of 192.168.1.0 255.255.255.0 to
192.168.0.2.

Or, add a static route on the D-Link (if possible) poingt to 192.168.1.1 via
192.168.0.2. The D-link will redirect if the default gateway of the Windows
2003 machine is 192.168.0.1.

> 3) From the Router I can ping the cable router

Yes, they are both on 192.168.0.x

> 4) From the Router I can ping the workstation

Yes, they are both on 192.168.0.x

Your error is a simple routing error. Unless all the devices speak RIP, it
is not helpful. The DLINK is doing the NAT to ine internet, right?
