This error is generated when restarting Apache, if a password was entered to encrypt the private key file. Apache on a Windows Server does not support encrypted private keys.
The SSLPassPhraseDialog is a directive within the Apache httpd.conf or ssl.conf that is not supported by Windows
To resolve this issue, remove the pass phrase from the RSA private key
Note: If someone gains access to the unencrypted key, they will be able to impersonate your company. The key is the identifying digital signature.
