Event ID 7020

Hi

I have 2 windows 2003 Servers R2, Both are on same LAN, and both are DC's. The first DC we promoted and that has all of the master roles is also the Exchange 2003 Server (i know its not ideal but budget was not there)

I had an issue that when the server rebooted i got the following error in system Log and Exchange MTA stack and Information store did not start, however both started manually. Looking at other event logs it implied that the server had a problem contacting the GC (which is itself!!). I made the 2nd DC a GC as well and now the problem has gone.

Does anyone have any idea's why that would happen and how i can troubleshoot the GC on Exchange server.

Thanks

Hi higgsy,

its due to service dependencies not starting before your exchange services - may have been one off

another idea, please back up the reg before attempting this:

SYMPTOMS
When you start Windows with Exchange installed, you may be notified by Service Control Manager with an error message similar to the following error message:
At least one service or driver failed during system startup. Use Event Viewer to examine the event log for details.

The Exchange Microsoft Exchange Information Store will not start. As a result, all services that depend on Information Store service will not be able to start.
You may find the following error events in Event Viewer:

On databases larger than 80 megabytes, the Microsoft Jet database engine transactions can use a lot of memory.

You can tune the version store in Windows Server 2003:

1. Use the Registry Editor to navigate to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermServLicensing\Parameters.

2. Add a MaxVerPages Value Name as a REG_DWORD data type and set the data value to a Decimal number between 256 and 2048. The default is 1024. For a large database, set it to 2048.

3. Exit the Registry Editor.

Try changing the service account to system.

Hi higgsy,

As Jay_Jay70 said is some kind of a dependency issue, the Information Store service uses the Global Catalog for message routing and mailbox lookup and if none are available it can't start or if running inmediately shutdown. There is a lag of time between the boot process and the server be ready for GC services, this is why the exchange services don't start and why it works installing another GC because the service find GCs automatically (not recommend, but you can modify this behaviour on ESM\First Administrative Group\Servers\server_name\Properties\Directory Access)

cheers
