    every webservice call taking 5 seconds

    Hi,

    I have built a windows app that makes calls to a webservice. Both webservice
    and windows apps are built with .net 2.0. The problem is... when I run the
    client Windows app on the dev machine, calls to the production webservice
    are very fast (milliseconds). When I run the exact same Windows app on a
    different machine... same log in, calling a webservice on the same
    production server.... EVERY call takes 5 seconds (not just the first call).

    I cannot understand why this would happen, or how to debug? It happens on
    any client machine except the dev computer.

    Any ideas?

    Thanks in advance!!
    James

      I would look at the settings for network proxies and make sure they're
      correct on the client machines. Same with DNS server settings. Maybe it
      takes five seconds just to connect to the server?

          Thanks for the suggestion John, unfortunately I checked the settings and
          they are all the same :(

          FYI - opening a website on the same server as the webservice is fast from
          the client machine

          Any other suggestions welcome!

              I fixed it!! Turns out that in the webservice where we log activity, there
              was a DNS lookup call. That call ran v fast for the dev machine, but takes a
              long time for clients (and eventually fails)... I removed the lookup now the
              webservice is VERY fast.
