This may be a TCP issue. This issue manifests itself on high-bandwidth + high latency links.

The Microsoft KB article # 224829 incorrectly states that "Timestamps and Window scaling are enabled by default..".

What actually happens is that when a Windows machine initiates a TCP connection, it does NOT advertise "Window scaling" by default.

This must be manually enabled by setting a registry entry, then rebooting:

(Save these lines to a file - suggested name: TCPIP-RFC1323.reg. This will allow error-free, consistent update of several machines) 

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parame
+ters]
    "Tcp1323Opts"=dword:00000003

[download]
This requires a reboot, in order to take effect.

Please refer to Microsoft KB 224829 for an explanation of this entry, as well as information on TCP Window Scaling.
