SYMPTOMS

Microsoft Exchange 2000 Server public folder server computers may experience extremely poor performance. When this problem occurs, one or more of the following behaviors may occur:
  • Users are prompted to re-enter their Exchange credentials.
  • E-mail functionality slows.
  • Users may lose their connection to the Exchange computer.
  • Outlook Address Book downloads may take longer than expected.

CAUSE

This problem may occur when slow domain controller responses cause a backlog of requests to reload the public folder hierarchy in the Microsoft Exchange Information Store service (Store.exe). A reload of the hierarchy should only be performed one time during a defined interval of time. This defined interval of time is typically 15 minutes. The symptoms that are described in this article occur because the time-out expires, and each client thread tries to reload the hierarchy.

On a computer that does not have the hotfix that is described in the "Resolution" section applied, the time-out value is not reset until after the client thread receives a Lightweight Directory Access Protocol (LDAP) response from a domain controller with the list of public folder server computers. This causes all the client threads to issue an LDAP request of their own. If there are many users on your network, this could exhaust the 100 remote procedure call (RPC) requests that can be open at a time.

RESOLUTION

Hotfix information

To resolve this problem, obtain the August 2004 Exchange 2000 Server Post-Service Pack 3 update rollup.

WORKAROUND

To work around this problem, configure the replication reload value to a 24-hour interval in the registry. If you apply the hotfix that is described in this article, you do not have to use this workaround.

To configure the replication reload value in the registry, follow these steps.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
  1. Click Start, click Run, type regedt32 in the Open box, and then click OK to start Registry Editor.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MsExchangeIS\<ServerName>\Public-(guid)
  3. On the Edit menu, click Add Value.
  4. In the Value Name box, type Replication Reload TLH Min.
  5. In the Data Type list, click REG_DWORD, and then click OK.
  6. In the Data box, type 86400, and then click OK.

    Note The value is the number of seconds between reloads. 86400 seconds is equal to 24 hours.
  7. Quit Registry Editor.
The replication value that you specified is only read when the public store starts. To force your Exchange 2000 computer to read the new value, dismount and then mount the public folder store. Do this at some point after work hours when the load on the system is very light.

To dismount and mount the public folder store, follow these steps:
  1. Start Exchange System Manager.
  2. Expand Servers, expand the server that you want, expand Storage_Group_Name, and then right-click Public Folder Store.

    Note If you have administrative groups defined, expand Administrative Groups, expand Administrative_Group_Name, expand Servers, expand the server that you want, expand Storage_Group_Name, and then right-click Public Folder Store.
  3. Click Dismount Store, and then click Yes to continue.
  4. Right-click Public Folder Store, click Mount Store, and then click OK to acknowledge that the store was successfully mounted.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.
