There appears to be something wrong with your setup, if you examine the 
file 'MS-AD_Schema_2K8_R2_Attributes.txt' (should be on your system, in 
a directory called ad-schema), you will this:

cn: ms-DS-Supported-Encryption-Types
ldapDisplayName: msDS-SupportedEncryptionTypes
attributeId: 1.2.840.113556.1.4.1963
omSyntax: 2
isSingleValued: TRUE
schemaIdGuid: 20119867-1d04-4ab7-9371-cfc3d5df0afd
systemOnly: FALSE
searchFlags: 0
attributeSecurityGuid: 77b5b886-944a-11d1-aebd-0000f80367c1

And your DC objects should have this:

msDS-SupportedEncryptionTypes: 31

Was the original DC a Samba 4 DC ?
