Security certificate

Hi. We are having a message saying that "This server could not prove that it is support.OUR-DOMAIN.com ; Its security certificate is from admin.footprintseducation.in . This may be caused by a misconfiguration or an attacker intercepting your connection.  

Error message below says: NET::ERR_CERT_COMMON_NAME_INVALID

Does anyone have any idea if this is something threatening?  Our domain is not footprintseducation!
