Connections that use impersonation under different identities may not work correctly in Windows 2000 Advanced Server SP4

Article ID: 833816

APPLIES TO

Microsoft Windows 2000 Advanced Server

SYMPTOMS

In a Microsoft Windows 2000 Advanced Server cluster environment, you may find that existing authenticated and trusted Link Control Protocol (LCP) connections that use impersonation do not work correctly. This problem occurs when you have multiple connections from various clients that may be logged in as different users. This problem only occurs in Microsoft Windows 2000 Advanced Server Service Pack 4 (SP4).

CAUSE

This problem may occur if you are running Windows 2000 Advanced Server SP4, and clustering is enabled. The problem occurs because of a change in the way that impersonation works in Windows 2000 Advanced Server SP4. On computers that use Windows 2000 Advanced Server Service Pack 3 (SP3) and earlier, you do not have to have a user right to impersonate a client. Therefore, some programs that use impersonation may not work correctly after you install Windows 2000 Advanced Server SP4.
