Make sure that you open port 23 on your firewall.  I would reconfigure the firewall to open port 23 to this server.

Follow-up to what NJComputerNetworks said:
If you have a router, make sure EVERY firewall has it open, and forwarded to that computer.

First of all, what is 192.168.0.2 ?

Is 192.168.0.2 a server, a router?  Is a telnet service running on it?
Try running WS Ping to scan the 192.168.0.2 IP to find out what services are running on it.
( you can access this free trial from http://www.ipswitch.com/downloads/index.asp )

I'm guessing that 192.168.0.2 is another device on your home/office network?  If so, you do not need to open any ports as the local network traffic should not be going through any router.

If you are tryin to use telnet to this device, is it a router?  If it's not a router, try using http://192.168.0.2

Question?
1. What is it that you intend to connect to when you type "Telnet 192.168.0.2"
2. From where are you trying to establish this connection. Comand prompt?

192.168.0.2  is the server and port 23 is open on the firewall and the server is running it.

What is it that you intend to connect to when you type "Telnet 192.168.0.2"
I was trying to connect internally because Microsoft Exchange was telling me that it could not connot to port 23!

From where are you trying to establish this connection. Comand prompt?
This is within domin not from out side.
