2641192 The badPwdCount attribute is not reset to 0 on a Windows Server 2008 R2-based PDC when the reset request is sent from an RODC
In a specific scenario, the badPwdCount attribute for a user account is reset to 0 on a Read-only Domain Controller. However, the badPwdCount attribute is not reset to 0 on the Domain Controller holding the Primary Domain Controller emulator (PDCe) FSMO role. The expected behavior is that the badPwdCount attribute is reset to 0 on both the RoDC and the PDC. Because of this issue, the user account will be locked incorrectly if the total amount of incorrect password attempts exceeds the value that is set in the Account Lockout Threshold Group Policy setting. This issue occurs because the Security Accounts Manager (SAM) server does not support badPwdCount attribute requests that come from an RoDC. A hotfix is available, that needs to be installed on all Read-Write Domain Controllers in domains with Read-only Domain Controllers.

2636585 Proquota.exe uses incorrect profile quota Group Policy settings in Windows Vista or in Windows Server 2008
On domain-joined Windows Vista Service Pack 2 and Windows Server 2008 SP2 boxes, with multiple Group Policy objects (GPOs) applied, each containing the Limit profile size setting (under User Configuration\Administrative Templates\System\User Profiles), the Profile Quota Manager tool (Proquota.exe) may receive incorrect profile quota settings. This behavior causes data loss if the incorrect quota size that is actually applied is too small.

The value of the thisUpdate time stamp in the OCSP response is outdated by 24 hours. A more recent time stamp value that is based on the latest-issued delta certificate revocation list (CRL) should have been used. A hotfix is available.

2634157 DNS name resolution fails when using a long CNAME or DNAME chain record in Windows Server 2008
CNAME and DNAME resource records can be used in DNS to point multiple DNS names to a single IP address. Chaining these records is considered a bad practice and under certain circumstances in Windows Server 2008 DNS, this can lead to subsequent lookup failures when the cache of the CNAME or DNAME chain expires. A hotfix is available.

This article introduces an update for Windows Server 2008 R2 that enables simple delegation in Active Directory Rights Management Services (AD RMS).
