IIS MachineKey Requirements for Load balancers ​

By default, all Passwordstate installs set the Machine Key in IIS to “Auto-Generate” which randomises the Validation and Decryption machine key on the web server – used for ASP.NET ViewState.

If you have multiple Passwordstate web servers being Load Balanced, you will need to manually set the MachineKey on all web servers – to ensure seamless failover of session state.

Below are the steps for this:

  1. On your primary web server, open Internet Information Services (IIS) Manager
  2. Browse to the Passwordstate website, and click on Machine Key icon
  3. Click the Generate Keys button on the right-hand side of the page, and then click the Apply button
  4. Copy the "C:\inetpub\Passwordstate\web-machineKey.config" file across to your second Passwordstate webserver, replacing the existing file
