Error adding server to SharePoint 2010 Farm

When I try to add another server to my existing SharePoint 2010 farm through the configuration wizard, the wizard gets to task 3 of 9 then comes back with the message:
Configuration Failed.  The error I get to in the log says this:

09/19/2012 18:25:54  11  ERR                          Task configdb has failed with an unknown exception
09/19/2012 18:25:54  11  ERR                          Exception: System.InvalidOperationException: The password for the account PDI\svc_sp_app_u, as currently stored in SharePoint, is not the same as the current password for the account within Active Directory. To fix this with PowerShell, run Set-SPManagedAccount -UseExistingPassword.
   at Microsoft.SharePoint.Administration.SPWindowsServiceInstance.Start()
   at Microsoft.SharePoint.Administration.SPWindowsServiceInstance.Provision(Boolean start)
   at Microsoft.SharePoint.Administration.SPFarm.Join()
   at Microsoft.SharePoint.PostSetupConfiguration.ConfigurationDatabaseTask.CreateOrConnectConfigDb()
   at Microsoft.SharePoint.PostSetupConfiguration.ConfigurationDatabaseTask.Run()
   at Microsoft.SharePoint.PostSetupConfiguration.TaskThread.ExecuteTask()

So I did some research and followed the steps on this page:
http://sharepoint.stackexchange.com/questions/30312/unable-to-change-sharepoint-account-password-in-sharepoint-2010

with no success.  When I first tried to add this new server, SharePoint crashed on the existing WFE because some of my service accounts were expired, so I reset the passwords in AD, used the Set-SPManagedAccount -UseExistingPassword command, and called Repair-SPManagedAccountDeployment to verify.  Both servers have been restarted since.  SharePoint seems to be running fine on my first WFE now, but I am still getting this error when trying to add this new server.  Any ideas?
