You are the messaging engineer for your company. Your company has a main office and 30 branch offices. Your company has a Microsoft Exchange Server 2003 messaging system. A routing group is configured for each office. As part of your transition to Exchange Server 2007, you recently deployed Client Access servers. You plan to deploy Hub Transport servers. You need to prepare the Exchange organization for the deployment of the Hub Transport servers. What should you do?
A.
Create new routing groups. Place the Exchange Server 2007 server objects into the new routing groups.
B.
Configure multiple IP addresses on all Exchange Server 2007 servers. Disable Windows Firewall for all
network connections.
C.
Create new Active Directory sites. Place the Exchange Server 2003 servers and the Exchange Server 2007
servers into separate sites.
D.
Suppress propagation of link state information on all Exchange Server 2003 servers.
Explanation:
Exchange 2003 uses a link state table to store its routing table and advertises configuration changes by link state updates. The routing group master retrieves updates from AD and coordinates the propagation of discovered changes to other servers in its routing group.Exchange 2007 neither employs the link state table nor supports relay of link state updates. Each 2007 Hub server separately queries AD to retrieve settings used to calculate a routing table and receive configuration updates.
When you install a Hub server in an existing Exchange 2003 organization which hosts multiple routing groups, the first 2007 Routing Group Connector is automatically created. Before implementing any additional connectors you may need, edit the Registry on each Exchange 2003 server to suppress propagation of minor link state updates between the 2003 and 2007 routing groups. This will prevent routing loops.
On each 2003 server:
1. Launch Regedit.
2. Locate HKLM\System\CurrentControlSet\Services\RESvc\Parameters.
3. Right-click Parameters. Select New > DWORD value. Name it SuppressStateChanges.
4. Double-click SuppressStateChanges.
5. In the Value data field, enter 1.
6. Close Regedit.
7. Restart the SMTP, Routing Engine, and MTA Stacks Services for this change to take place.http://technet.microsoft.com/en-us/library/bb125223.aspx
