Handling Service Password Changes
Updated: October 24, 2012
Many installations require all users to change passwords periodically. Use the following procedure to change the password of the service account.
Log out of the service account.
Log back into the service account using the new password.
Run the following cmdlets from the PowerShell prompt of Microsoft AppFabric Server:
$AccountPassword = ConvertTo-SecureString -String NewPassword -AsPlainText -Force Stop-WFHost -Verbose Update-WFHost -RunAsPassword $AccountPassword –Verbose Start-WFHost -Verbose
You can now freely add or remove nodes from the farm.
