After upgrading to Windows 2008 R2, the following error is seen:Kerberos ETYPE not supported from KDC
Starting from Windows 2008 R2, the encryption type DES is no longer supported by default.
Applications like NFSv4 and Oracle will fail when trying to get service ticket from a KDC/DC running on Win2008R2.
The registry below needs to be set on EVERY DC running Win2008R2 in the domain for it to work with DES. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kdc]
Applications like NFSv4 will need to release new version which supports AES encryption type.
For more information, please see the following links:
If DES for NFSv4 is needed, then it will be necessary to fix both the adclient side, as well as AD side for enctype.
Win2003 -> Win2008 upgrades change the KRBTGT password hash. This operation invalidates all TGTs that were issued prior to upgrade.
Adclients need to be restarted by issuing the centrifydc restart
