This error occurs when too much data is sent to the server on a request. This can be caused by a large file attachment.
To fix this, first locate the page on which this occurred. Then, edit the web.config file that exists in your Password Reset Server installation directory. Next, search for the <location> tag that contains the page on which the error occurred. For example, if you received this error on the CreateUser.aspx, you would want to look for the following section:
<location path="CreateUser.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
If you located the tag, then add the following line directly above the closing </system.web> tag:
<httpRuntime maxRequestLength="20480" executionTimeout="600" />
So, in this case, your CreateUser node should look like this:
<location path="CreateUser.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
<httpRuntime maxRequestLength="20480" executionTimeout="600" />
</system.web>
</location>
In some cases, this tag may not exist in your web.config file. When this occurs, create a new section right before the closing </configuration> in the file. This closing tag usually is on the last line of the file. For example, if you received the error on DomainSynchronize.aspx, add the following lines to your web.config file above the closing </configuration> tag:
<location path="DomainSynchronize.aspx">
<system.web>
<authorization>
<allow users="?"/>
</authorization>
<httpRuntime maxRequestLength="20480" executionTimeout="600" />
</system.web>
</location>
