I understand why I'm getting this error, but am having a problem trying to implement a solution.
The original error was the following:
Viewstate verification failed. Reason. The viewstate supplied failed integrity check.
I have tried overriding the machine.config file by adding a machineKey property in the web.config file of the application. I have tried three different versions of this file and am still coming out with the same error: Unrecognized attribute 'decryption'
Here are the three versions of the machineKey attribute I've used: Note that the generated key was retrieved from the following website: http://aspnetresources.com/tools/machineKey
<machineKey validationKey="..." decryptionKey="..." validation="SHA1" decryption="AES" />
<machineKey compatibilityMode="Framework20SP1" validationKey="..." decryptionKey="..." validation="SHA1" decryption="DES" />
<machineKey validationKey="..." decryptionKey="..." validation="SHA1" decryption="DES" />
Note that the web servers are using the .Net 1.1 Framework and using IIS 6. I know the above solutions work for .Net 2.0+, but have never encountered this for the .Net 1.1 version.
Can someone please inform me the correct usage of how to get around this error for the .Net 1.1 version and IIS 6?

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<compilation defaultLanguage="vb" debug="false" />
<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.
"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customErrors mode="Off" />
<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"
"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<authentication mode="Windows" />
<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->
<authorization>
<allow users="*" /> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>
<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.
-->
<trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true" />
<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests belong to a particular session.
If cookies are not available, a session can be tracked by adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionState
mode="InProc"
stateConnectionString="tcpip=999.0.0.9:99999"
