SYMPTOMS
After you upgrade to Microsoft Exchange Server 2003 Service Pack 2 (SP2), the Microsoft Exchange Information Store Service may not start. Additionally, the following event is logged in the Application log: Event ID: 5000

Source: Exchange IS

Description: Unable to initialize the store service. Failed to search for MSEXCHUCE in DS. 0x80004005



CAUSE
This problem may occur if a query for the Intelligent Message Filter (IMF) is made against a domain controller that is under a heavy load. When the Exchange Information Store service in Exchange Server 2003 SP2 starts, it issues a query to check an attribute for the IMF. This query uses lots of resources. When this query is made against a domain controller that is already under heavy load, the domain controller may not respond to the query in a timely manner. Therefore, a time-out may occur during the LDAP query. If a time-out occurs several times, the Exchange Information Store service may not start.



Hotfix information
A supported hotfix is now available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next service pack that contains this hotfix.

Hotfix installation information
After you apply this hotfix, the query uses an indexed attribute. Therefore, the domain controller does not have to enumerate as many objects to build the response.

Prerequisites
You must install Microsoft Exchange Server 2003 Service Pack 2 (SP2) before you install the hotfix.

Restart requirement

File information
The global version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time.

WORKAROUND
To work around this problem, you can temporarily hardcode the Directory Access (DSAccess) component to query domain controllers that are not heavily loaded. You must select domain controllers that can respond to the query before the two-minute time-out period expires. To do this, follow these steps:
 * 1) Start Exchange System Manager.
 * 2) Expand Administrative Groups, expand First Administrative Group, and then expand Servers.
 * 3) Right-click the server that you want, and then click Properties.
 * 4) Click the Directory Access tab.
 * 5) In the Show box, click Domain Controllers.
 * 6) Click to clear the Automatically discover servers check box, and then click Yes when you receive the warning message.
 * 7) Click Advanced, and then click Find Now.
 * 8) In the Search results box, click an appropriate entry for a Microsoft Windows Server-based computer, and then click OK three times.
 * 9) Exit Exchange System Manager.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
