Recently, the MS PSS team received some reports regarding issues happening on the Windows Vista computers located in a domain.
This issue is finally determined to be linked to a new feature included with the Vista -TCP Auto Tuning, which uses a scaling factor communication between the server and client, to negotiate a bigger window size during connection establishment so that more traffic can be transported in less time. Windows XP and earlier versions do not have this feature.
You can disable this feature as a workaround and this will certainly tell the tale on what the problem is if the issue no longer happens afterward. From a command prompt:
netsh interface tcp set global autotuninglevel=disabled
If the issue no longer occurs, this reveals that you have a network device in your environment that doesn’t support RFC 1323 “TCP Extensions for High Performance”.
