If there's one thing that's true of all busy Exchange servers, it's that they generate massive amounts of disk I/O. There's a joke around here that Exchange is the world's biggest hard disk diagno...

Donna, In Exchange2000 there is no registry key to increase the log buffers - it is now done by modifying the 'msExchESEParamLogBuffers' value via the ADSIEDIT utility. The default in Ex2000 is 84, however you should manually set the value to 500 (it is not set to 500 in SP3 either).
You should set the value on the 'Information store' & 'storage group' objects for the Exchange server via ADSIEDIT.
Here's how to do it:-
1. Use ADSI Edit to connect to the Configuration Container Naming Context of your Active Directory.
2. Go to the following path:
Configuration Container | CN=Information Store,CN=<server>,CN=Servers,CN=<Admin Group>,CN=Administrative Groups,CN=<org>,CN=Microsoft Exchange,CN=Services,CN=Configuration
3. Right-click the Information Store object, and then click Properties.
4. Change the Select which properties to view drop-down list box to Both.
5. Select the msExchESEParamLogBuffers attribute and type in the value of 500. Although no value will be present, the default will be 84.
6. Remember to click Set after changing the edit field for the attribute.
7. Now (similar steps as 3 - 6) set the msExchESEParamLogBuffers attribute for the individual Storage Group object(s) below the Information Store attribute of the server.
7. Close the ADSI Edit tool by closing the MMC console application.
8. Wait for Active Directory replication to replicate this new value throughout the forest.
9. Restart the Information Store service on the Exchange 2000 server.
