Windows client damage authorization header (Kerberos) => IIS 400 (Bad Request)

Hello,

ESET NOD32 Antivirus 4 Business Edition is a pretty old.  As a matter of fact, it was replaced with ESET Endpoint Antivirus several years ago.  Is there a particular reason you haven't upgraded (compatibility issue or system requirements or something)?  Your ESET NOD32 Antivirus Business Edition license would migrate over ESET Endpoint Antivirus for free, although you may have to contact customer support to get a license key reissued in the newer format.

Regards,
