This topic provides information about how to troubleshoot the Microsoft Exchange Information Store service and the System Attendant service if they fail to start after a reboot. You may see the following error: "Unexpected error: No site name is available for this machine. Facility: Win32 ID no: c007077f Microsoft Exchange System Attendant error occurred."
The Application event log may also include Event ID messages related to error 1005 and 2114.
This issue may occur because a new site has been created in Active Directory Sites and Services, where previously there had only been a Default-First-Site-Name. In addition, the subnet in which the Exchange Server 2007 server resides is not associated with any site in Active Directory Sites and Services.
To resolve the problem, create a new subnet and add the Exchange 2007 IP address.
Before You Begin
To perform this procedure, the account you use must be delegated membership in the local Administrators group. For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.
To create a new subnet and add the Exchange 2007 IP address
Click Start, click Programs, point to Administrative Tools, and then click Active Directory Sites and Services.
Double-click the Sites node that corresponds to the site where the Exchange server resides. Right-click Subnets.
Click New Subnet on the shortcut menu.
Type the IP address and the subnet mask of the subnet, and then click One Site on the Site Name list.
Click OK to close the New Object-Subnet dialog box.
Force Active Directory replication. For more information about forcing replication, see Force replication over a connection.
