SYMPTOMS
When you try create a dump file of the Microsoft Exchange Information Store by using the ADPlus or the Userdump utilities on a Microsoft Windows 2000 Server-based cluster or on a Microsoft Windows Server 2003-based cluster that has either Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 installed, the Exchange resources may stop working and fail over to another cluster node.



Method 1: Turn off the &quot;Affect the group&quot; resource option
To resolve this issue, turn off the Affect the group resource option, collect the information store dump file, and then turn back on the Affect the group resource option. To do this, follow these steps:
 * 1) Start Cluster Administrator.
 * 2) Expand the Server container, and then expand Active Resources.
 * 3) Right-click the Exchange Information Store instance that you want, and then click Properties.
 * 4) Click the Advanced tab, click to clear Affect the group, and then click OK.
 * 5) Quit Cluster Administrator.
 * 6) Use the ADPlus utility or the Userdump utility to collect the information store dump file.
 * 7) After you have collected the information store dump file, turn on the Affect the group resource option in Cluster Administrator.

Method 2: Increase the Exchange Server time-out value
To resolve this problem, you can increase the Exchange Server time-out value to 600,000 milliseconds (600 seconds or 10 minutes). The default time-out value in Exchange 2000 Server and in Exchange Server 2003 is 180,000 milliseconds (180 seconds or 3 minutes).

Exchange 2000 Server
In Exchange 2000 Server, the Exchange storePendingTimeOut property controls the length of time that the resource can remain in an unresponsive state before a time-out occurs. To increase the time-out value in Exchange 2000 Server, follow these steps:
 * 1) Open a Command Prompt window.
 * 2) To view the PendingTimeOut property settings, type cluster res &quot;resource name&quot; /prop, and then press ENTER.
 * 3) To change the value of the PendingTimeOut property, type cluster res &quot;resource name&quot; /prop PendingTimeOut=600000:DWORD, and then press ENTER.

This value is read when the resource first comes online. If you make a change, you must take the resource offline and then bring the resource online.

Exchange Server 2003
In Exchange Server 2003, the Exchange store IsAliveTimeOut property controls the length of time that the resource can remain in an unresponsive state before a time-out occurs. To increase the time-out value in Exchange Server 2003, follow these steps:
 * 1) Open a Command Prompt window.
 * 2) To change the value, type cluster res /priv IsAliveTimeout=600000:DWORD, and then press ENTER.

This value is read when the resource first comes online. If you make a change, you must take the resource offline and then bring the resource online.
