SYMPTOMS
After you upgrade from Microsoft Windows 2000 Service Pack 1 (SP1) to Windows 2000 Service Pack 2 (SP2), Exchange 2000 services may not start.

The following events may be logged in the Application event log when you try to start the System Attendant service:

Source: MSExchangeSA

EventID: 1005

Unexpected error The Run server you requested is paused. Facility: Win32 ID no: c0070951 Microsoft Exchange System Attendant occurred.

Source: MSExchangeDSAccess

EventID: 2071

Process MAD.EXE&quot; (PID=2076). All the remote Domain Controller Servers in use are not responding.



CAUSE
This issue can occur if the Microsoft Winsock Proxy Client 2.0 is installed and enabled. After you apply Windows 2000 SP2, if the Winsock Proxy Client 2.0 is installed and enabled, the name resolution may not work, which causes Exchange functions and features to stop working correctly.



WORKAROUND
To work around this issue, either disable or uninstall the Winsock Proxy Client or upgrade to Microsoft Internet Security and Acceleration (ISA) Server and the ISA Winsock client.
