SECTION 1
Problem
IP packet isn’t reaching
its destination
Possible Cause
Run the PING command
to check the connection
Possible Solution
Perform the following steps to run the PING
command to check if the IP packet is correctly
delivered to the destination.
To run the PING command, the TCP/IP
protocol must be installed. First you will
determine your IP address, then you will make
sure your IP address can respond, and then
you will make sure other computers can be
addressed.
1. Windows 2000: Click [Start]
→
[Programs]
→
[Accessories]
→
[Command Prompt].
Windows XP: Click [Start]
→
[All Programs]
→
[Accessories]
→
[Command Prompt].
2. Type: ipconfig >
directory\filename where
directory and filename represent the
location at which you want to find the IP
address.
3. Click [Enter], then go to the location you
specified above. The IP address for your
system will be contained in the file.
4. To check that your IP address is functioning
properly, go back to the DOS prompt and
type: ping
<IP address>, then press [Enter].
You will receive several replies, followed by
the PING statistics (similar to below).
5. To check that your system is
communicating with other systems, go to
the DOS prompt and type: \>ping
XXX.XXX.XXX.XXX. (With the destination
IP address in place of
XXX.XXX.XXX.XXX).
Example: if the destination IP address is
10.0.1.3: C:\>ping 10.0.1.3
A message similar to the following appears if
the connection is successful.
Pinging 10.0.1.3 with 32 bytes of data:
Reply from 10.0.1.3: bytes=32 time=1ms
TTL=32
Reply from 10.0.1.3: bytes=32 time<10ms
TTL=32
Reply from 10.0.1.3: bytes=32 time=4ms
TTL=32
Reply from 10.0.1.3: bytes=32 time<10ms
TTL=32
If the connection fails, [Request timed out],
[Destination host unreachable], or a similar
message appears. In this case, refer to the
“ Other computers are not displayed” portion
of this chapter.
