You are the network administrator for your company. The company operates a main office and one branch office.
The network consists of a single Active Directory domain. The two offices are connected by a dedicated framerelay line. Each office contains one domain controller.
Each domain controller runs the DNS Server service and hosts an Active Directoryintegrated zone.
In each office, all computers are configured to use the local DNS server for DNS name resolution.
Each office contains one Exchange Server 2003 computer, which hosts all user mailboxes for that office.
The domain controller and the Exchange server in the main office are named DC1 and Exch1, respectively.
The domain controller and the Exchange server in the branch office are named DC2 and Exch2, respectively.
Monday morning, users in the branch office report that they cannot connect to Exch2.
You discover that no Exchange services will start on Exch2. When you restart Exch2, the services fail to start.
You discover that the framerelay line between the two offices is in a state of failure. After restoring the framerelay line, you restart Exch2.
All Exchange services start successfully. You need to ensure that failures in the framerelay line will not prevent either Exchange server from starting normally.
