A workstation with IP address 172.16.1.5 and subnet mask 255.255.255.0 is unable to see
NT server David in its browse list. David’s IP address is 172.16.2.1 with the same subnet
mask. The workstation cannot ping David’s IP address. Which of the following is the
most likely cause of this problem?

A.
The workstation needs to point to a WINS server that knows David’s IP address.

B.
The default gateway on the workstation is wrong.

C.
TCP broadcast forwarding is not enabled.

D.
The workstation’s domain account has been disabled or has expired.

Explanation:
The workstation and the server are on different subnets. The only way
to get the traffic to cross subnets is via a router. This requires the proper definition
of the default gateway. The default gateway is used when a packet has to be routed
to another subnet, and is th address of the router that will move the packet. In this
case the default gateway must be wrong.
Incorrect Answers:
A: Names are not being used, just plain IP addresses. So, WINS or DNS would not xomeinto play
here. Also, there is an inability to ping the IP address, and ping does notinterface with WINS.
C: Broadcasts are not being used here.
D: Ping is being used, and is not dependent on the domain account.
