Is there a way to do a tracert but on a specific port
number? IE, trying to figure out why we can not access an
application where we have the IP and specific port that we
are to use but no matter what we try we can't get to this
application. As always, thank you for your help!!

Regards,
Alan
 
accessing application remotely? Like an SQL server?

try netstat -an on machine running application to see if port is
open... then perhaps telnet to that port remotely to see if you get a
connection

I don't know of a tool to do that exactly but you have a couple of options.

Use a port scanner such as the free Superscan 4 from Foundstone to scan the remote IP
address to see what ports it shows as open.

View the firewall logs for events at the time you tried to run the application for
dropped/denied packets from the initiating client.

Use a packet sniffer such as the free Ethereal on each end to capture the packet
exchange sequence of the traffic for initiating the access to the application. W2K
server also has the built in netmon. I find Ethereal easier to use and configure
filters however. Things to look for are packets sent to the server from the client,
what ports they are sent one, if responses are received, any error messages, etc. On
the server end you want to see if it is receiving the packets from the client and if
it is responding or not. --- Steve
