This issue occurs if the RSA key used to encrypt the domain user password is from a different machine. In View Manager 5.1, View Composer can be installed on a standalone machine and, therefore, may not exist in the same machine as it did in the previous version of View Manager.


To resolve this issue, reset the domain user password in the View Administrator console.
To reset the domain user password:
  1. Log in to the View Administrator console.
  2. Navigate to View Configuration > Servers.
  3. Click the vCenter Servers tab.
  4. Select your vCenter Server and click Edit
  5. In the vCenter Server tab, click Edit under View Composer Server Settings.
  6. Under Domains, click Verify Server Information.
  7. Select your domain and click Edit.
  8. Enter the password for the domain user and click OK.

    You are now able to deploy new pools successfully.
