Now I can't edit the tcp_window_scaling file It's a configuration property so the file system you see it in is showing the state of the running system and is not persistent. You can set it and all sorts of other goodies in /etc/sysctl.conf > On a related subject, how does one detect where the window scaling > issue is being caused? Connect to multiple sites, if only one shows the problem you know who to blame, if they all do then start your end, if some do then its more fun but that rarely is the case. Usually its a broken firewall or NAT box. Alan
