Exchange 5.5 Errors

I have a lot of the following in the eventlogs of one of my exchange servers:

Event Type: Error
Event Source: MSExchangeDS
Event Category: Internal Processing
Event ID: 1171
Date: 1/28/2003
Time: 15:27:09
User: N/A
Computer: ZABRYSVCL04EX01
Description:
Exception e0010002 has occurred with parameters 9 and 0 (internal ID 30809ec). Contact Microsoft Technical Support for assistance.

I tried looking on Technet, but could not find anything related to this.

The exchange installation is a cluster with 2 nodes, running Windows 2000 SP3, Exchange 5.5 SP4. This is a brand new installation, and the machine has almost none mailboxes on at the moment.
