don't get response at dynamic IP address?

[linda.chen]

Greeting.

We have a web service which is written in ASP.net (C#). When a user
makes a request, it takes a while (average 100 seconds) to get the
response.

One of our users has dynamic IP address. He is complaining that he
does not get the response back. When I checked our log file from the
server, I can see the whole process had been completed from the
server. Why the user did not receive the response? Does dynamic IP
cause problem (IP changes after making request?)? How do I solve this
problem?

Regards,

Ask him to try it from IE; I think it is firewall/proxy problem mor.

This almost certainly has nothing to do with a dynamic IP address, unless
he's losing his connection to the Internet and reestablishing it. If that is
the case, then it is a network problem, and you aren't going to be able to
do anything about it. In TCP/IP, a "connection" includes the source and
destination IP addresses, so if his were to change during a connection,
then, by definition, the connection is gone.

That said, it is almost certainly not a problem with the dynamic IP address,
so you should look elsewhere for answers. For instance, this user was unique
in having a dynamic IP address. In what other ways is his network
environment unique?
