got a really strange one for you all.
I have a network setup using a linux machine as a gateway between various network segments (on seperate nic's) and virtual machines (one of which is a mail server) all managed by shorewall and bind9.
This has all been running happily for ages, but on the weekend the servers went down and were rebooted. Since then, the windows machine (ONLY) are having problems opening anything of any size on the network. For example, email has a web page that will open to the point of login, and then hang. The mail clients can download the headers of messages, but not the body of the messages. Opening shared documents is no issue, but saving them is VERY VERY slow and usually times out. However, Mac and Linux machines have no issues at all. This is windows only, and only on the internal network. Access to all of this from outside, on any platform, is no problem.
I see this same behaviour from a windows machine running as a virtual box client on a linux host that has no issues.
I'm out of ideas. I've done packet sniffing, and apart from a bunch of retries from the windows machines that I don't see on Linux, no issues that jump out at me.
How would you suggest I try and fault find this? What does the windows stack do differently to the linux/mac stack?
