IIS error - Unable to display page or site - .NET framework error is displayed

If you are using IIS with .Net framework web site you need to install .Net after IIS.

If you install IIS after .Net framework you need to run:

C:\WINDOWS\Microsoft.NET\Framework\".net version"\aspnet_regiis.exe

If it doesn't work you can run it with the following parameters
-ua > to uninstall all versions
-i > to install that specific version

Other Parameters:
-i - Install this version of ASP.NET and update scriptmaps
at the IIS metabase root and for all scriptmaps below
the root. Existing scriptmaps of lower version are
upgraded to this version.
-ir - Install this version of ASP.NET, register only. Do
not update scriptmaps in IIS.
-enable - When -enable is specified with -i or -ir, ASP.NET will also
be enabled in the IIS security console (IIS 6.0 or later).
-s - Install scriptmaps for this version at the specified path,
recursively. Existing scriptmaps of lower version are
upgraded to this version.
E.g. aspnet_regiis.exe -s W3SVC/1/ROOT/SampleApp1
-sn - Install scriptmaps for this version at the specified path,
non-recursively. Existing scriptmaps of lower version are
upgraded to this version.
-r - Install scriptmaps for this version at the IIS metabase
root and for all scriptmaps below the root. All existing
scriptmaps are changed to this version, regardless of
current version.

version of ASP.NET installed on the machine.

Set the default Zoom Level in Internet Explorer 7

Question
I upgraded to IE 7. The zoom begins @ 100% each time I start IE. I want it to be 75% but cannot make it default to it. Do you know how to do this?
Answer
By default, Internet Explorer 7 resets the Zoom level to 100% for every new window and new tab opened. To preserve your Zoom Level setting, use these steps:
Open Internet Explorer
From the Tools menu, choose Internet Options
Select the Advanced tab
Under Accessibility, deselect the following option:
Reset Zoom level to 100% for new windows and tabs
Click OK
The user specified Zoom level setting must be preserved from now on.
