trace??
You mean tracert, right
From 2000 Help:
Tracert
This diagnostic utility sends Internet Control Message Protocol (ICMP) Echo packets to the destination with different Time To Live (TTL) values to determine the route taken to reach the destination. Each router along the path must decrement the TTL on a forwarded packet by at least 1, so the TTL is effectively a hop count. When the TTL on a packet reaches 0, the router should send an "ICMP Time Exceeded" message back to the source system. Tracert first sends an Echo packet with a TTL of 1, then increments the TTL by 1 with each subsequent transmission until the destination responds or the TTL reaches the maximum value, thus determining the route. The route is determined by examining the "ICMP Time Exceeded" messages sent back by intermediate routers. However, some routers silently forward packets containing expired TTL values, and tracert cannot see them.
tracert target_name
Parameters
/d
Specifies not to resolve addresses to computer names.
-h maximum_hops
Specifies the maximum number of hops to search for the target.
-j computer-list
Specifies loose source routing along computer-list.
-w timeout
Waits the number of microseconds specified by timeout for each reply.
target_name
The name of the target computer.
