Certain encryption types are no longer considered secure. The DES and RC4 encryption suites must not be used for Kerberos encryption. Note: Organizations with domain controllers running earlier versions of Windows where RC4 encryption is enabled, selecting "The other domain supports Kerberos AES Encryption" on domain trusts, may be required to allow client communication across the trust relationship.
To fix this configure the policy value for
Computer Configuration
|_ Windows Settings
|_ Security Settings
|_ Local Policies
|_ Security Options
|_ Set "Network security: Configure encryption types allowed for Kerberos" to "Enabled" with only the following selected:
AES128_HMAC_SHA1
AES256_HMAC_SHA1
