Hi all,
I have a very strange problem - we have a number of vb6 and vb.net applications that have been written in house. These are used by a number of users with no problems, however one user is experiencing extremely slow response from all our vb6 and .net applications.

So far, we have:
a. plugged another computer with the same configuration into his network port - great response.
b. run the same sql stored procs through SQL Advantage (like sql server manager) - great response, even when returning > 1mb of records
c. run "winstress" to check that his memory wasn't corrupt (or used by "midnight spares") - no problems (1gb RAM)
d. defragged his hard drive - no difference
e. had the user sign on to a different machine - great response
f. checked running processes to see if he has something running that he shouldn't - no difference between his and my machine.
g. checked the network topology - both his and my machine are computer->switch->firewall->switch->switch->server
h. checked other (MS) applications that go to the server - great response

No other user is experiencing these problems - does anyone have any ideas what it could be?
