Encountering windows network/DNS problems !

[Viraj]

Lately Windows networks often get blocked that might seem a problem of DNS, but that really isnt. In few words windows does not resolve the host names which are considered to be perfect despite the configured DNS, nslookup comes up with a "strange" network error when searching for the DNS of a domain.

This happens on a network which is a Windows Vista or Windows 7 machine, the operating system sends packets in the network that sometimes collide with the TCP / IP. By testing various configurations of the management of TCP / IP in Windows Vista/ Windows 7, I found a solution, you must disable autotuning EE protocol that avoids the generation of these packets which collide.

Here is the string to disable the auto-tuning on Windows Vista and Windows 7:

ipconfig / flushdns
netsh interface tcp set global autotuninglevel = disabled

Also, if network problems are also present on Windows XP run even a restart of the DNS cache of the system:

net stop dnscache
net start dnscache

Let us know if any further assistance is required into this
