SYMPTOMS
After you apply the Q299687 Windows 2000 security hotfix or the Q311401 Windows 2000 security rollup package on the global catalog server, the following symptoms may occur:  Existing MAPI client computers cannot browse the global address list.

The name could not be resolved. The name could not be matched to a name in the address list.

 When you compose a new mail message, the names are not resolved.



CAUSE
This issue can occur if you use the Q299687 Windows 2000 security hotfix and you set the RestrictAnonymous registry key to a value of 0x2. In this scenario, the global catalog server does not allow anonymous access, and Exchange Server and Outlook cannot access Active Directory.

NOTE: The Q299687 Windows 2000 security hotfix is included in the Q311401 Windows 2000 security rollup package.



RESOLUTION
The problem caused by the Q299687 hotfix has been fixed in Windows 2000 SP3. To resolve this issue, upgrade your global catalog servers to Windows 2000 SP3.
