yes, that does show up. if I type tracert 192.168.0.118
it returns 1<10ms <10ms <10ms> 192.168.0.118
It never gives me the host name associated with
192.168.0.118.

Try this:
Start | Run | Type: cmd | OK |
When the cmd window opens type: tracert | ENTER
Does this show up??
=========
Usage: tracert [-d] [-h maximum_hops] [-j host-list] [- w timeout]
target_name
Options:
-d Do not resolve addresses to hostnames.
-h maximum_hops Maximum number of hops to search for target.
-j host-list Loose source route along host- list.
-w timeout Wait timeout milliseconds for each reply.
==============
If this shows up, tracert.exe is working. If you get another
message it may not be working. What do you get??

Hope this helps. Let us know.

Wow, now that was a wealth of knowledge. Thanks.
Unfortunately, it appears tracert just isn't working on
this box. Any way to repair it?

Make sure you aren't using the -d option >>>
[[Do not resolve addresses to hostnames.]]
To trace a path by using the tracert command
. Open Command Prompt, and type the following:
tracert host_name
Or, type tracert ip_address
where host_name or ip_address is the host name or IP address,
respectively, of the remote computer.
For example, to trace a connection route from this computer to
www.microsoft.com, type the following at a command prompt:
tracert
www.microsoft.com
If you do not want the tracert command to resolve and display the
names of all routers in the path, use the -d parameter. This
expedites the display of the path. For example, to trace a path
from this computer to
www.microsoft.com without displaying the
router names, type the following at a command prompt:
tracert -d
www.microsoft.com
Note
. To open command prompt, click Start, point to All Programs,
point to Accessories, and then click Command Prompt.
. The tracert command traces the path by sending Internet Control
Message Protocol (ICMP) Echo Request and Echo Reply messages
(similar to the ping command) to produce command- line report
output about each router that is crossed and the roundtrip time
(RTT) for each hop. Packet filtering policies on routers,
firewalls, or other types of security gateways might prevent the
forwarding of this traffic. . If tracert is unsuccessful, you
can use the command output to help determine at which
intermediate router forwarding failed or was slowed. . For
details about packet forwarding and packet loss at each router
and link in the path, use the pathping command. ==============
Tracert
Determines the path taken to a destination by sending Internet
Control Message Protocol (ICMP) Echo Request messages to the
destination with incrementally increasing Time to Live (TTL)
field values. The path displayed is the list of near-side router
interfaces of the routers in the path between a source host and a
destination. The near-side interface is the interface of the
router that is closest to the sending host in the path. Used
without parameters, tracert displays help.
Syntax
tracert [-d] [-h MaximumHops] [-j HostList] [-w Timeout]
[TargetName]
Parameters
-d : Prevents tracert from attempting to resolve the IP addresses
of intermediate routers to their names. This can speed up the
display of tracert results.
-h MaximumHops : Specifies the maximum number of hops in the path
to search for the target (destination). The default is 30 hops.
-j HostList : Specifies that Echo Request messages use the Loose
Source Route option in the IP header with the set of intermediate
destinations specified in HostList. With loose source routing,
successive intermediate destinations can be separated by one or
multiple routers. The maximum number of addresses or names in the
host list is 9. The HostList is a series of IP addresses (in
dotted decimal notation) separated by spaces.
-w Timeout : Specifies the amount of time in milliseconds to wait
for the ICMP Time Exceeded or Echo Reply message corresponding
to a given Echo Request message to be received. If not received
within the time-out, an asterisk (*) is displayed. The default
time-out is 4000 (4 seconds).
TargetName : Specifies the destination, identified either by IP
address or host name.
-? : Displays help at the command prompt.
Remarks
. This diagnostic tool determines the path taken to a destination
by sending ICMP Echo Request messages with varying Time to Live
(TTL) values to the destination. Each router along the path is
required to decrement the TTL in an IP packet by at least 1
before forwarding it. Effectively, the TTL is a maximum link
counter. When the TTL on a packet reaches 0, the router is
expected to return an ICMP Time Exceeded message to the source
computer. Tracert determines the path by sending the first Echo
Request message with a TTL of 1 and incrementing the TTL by 1 on
each subsequent transmission until the target responds or the
maximum number of hops is reached. The maximum number of hops is
30 by default and can be specified using the -h parameter. The
path is determined by examining the ICMP Time Exceeded messages
returned by intermediate routers and the Echo Reply message
returned by the destination. However, some routers do not return
Time Exceeded messages for packets with expired TTL values and
are invisible to the tracert command. In this case, a row of
asterisks (*) is displayed for that hop. . To trace a path and
provide network latency and packet loss for each router and link
in the path, use the pathping command. . This command is
available only if the Internet Protocol (TCP/IP) protocol is
installed as a component in the properties of a network adapter
in Network Connections
Examples
To trace the path to the host named corp7.microsoft.com, type:
tracert corp7.microsoft.com
To trace the path to the host named
corp7.microsoft.com and prevent
the resolution of each IP address to its name, type:
tracert -d corp7.microsoft.com
To trace the path to the host named
corp7.microsoft.com and use the
loose source route 10.12.0.1-10.29.3.1-10.1.44.1, type:
tracert -j 10.12.0.1 10.29.3.1 10.1.44.1 corp7.microsoft.com

Why doesn't tracert work the same in XP as it does in
W2K? I just want to get the hosts names associated with a
specific IP address. These hosts are workstations on the
network.

In W2K, tracert will give me the host name if I enter the
IP and the IP if I enter the host name. Why doesn't that
do the same in XP and what do to get the host name from an
IP address?
