How to Fix Certificate Errors on Your Computer
Getting the "An Input Field contains an invalid X500 characters" certificate error when using the Web Server Certificate Wizard is a fairly common error and can be easily remedied. The root of the certificate error involves the use of X500 characters, such as a "," in the "Organization" field.
