Exchange OWA Redirect

When setting up an exchange server and configuring OWA, you may want to create an AutoRedirect for your end users so that they do not have to type the complete URL. This is most simply accomplished by creating a default.htm file in c:\inetpub\wwwroot (or wherever the default web is loaded). In this file, place the following line of info (note to replace parenthasis with gt and lt symbols).

Exchange 2007
(script language="'JavaScript'")window.location='https:///owa';(/script)

Exchange 2000/2003
(script language="'JavaScript'")window.location='https:///exchange';(/script)"

This will allow redirection to the secured page for logon.

Speed Up Network Connections in Vista

With Windows Vista Microsoft has introduced new features to the TCP stack. In some situation, these features may adversly affect network performance. Therefore you may want to consider disabling them. These "features" are known as Receive Side Signaling (RSS), AutoTuning, and Chimney. To view the current setting for these features launch an elevated command prompt and type (note that all commands issues hereafter must be run from an elevated command prompt):

netsh interface tcp show global

To disable these, issue the following commands:

netsh interface tcp set global autotuning=disabled
netsh interface tcp set global chimney=disabled
netsh interface tcp set global rss=disabled


To re-enable the original settings, issue:

netsh interface tcp set global autotuning=normal
netsh interface tcp set global chimney=enabled
netsh interface tcp set global rss=enabled


Note that to re-enable autotuning set it to normal.
