Website throws 401 error

[satya]

I have installed MailEnable Enterprise premium latest version

When browse the web services (MailEnable Protocols) its shows below error. Attached the error details.
-------------------Error-------------------------------
HTTP Error 401.2 - Unauthorized
You are not authorized to view this page due to invalid authentication headers.

Tried resolution mentioned by MailEnable in link https://www.mailenable.com/kb/content/article.asp?ID=ME020618
But it did not resolve the issues.

Any pointer will be a great help.

Hi,

Inspect the Windows event log for more detail when the error is reported in the browser. Look for WAS warnings or failures in the system and application log. Most likely the problem is a password mismatch.
