Modifying Host Properties in the BizTalk Administration Console

For information about the user rights required to modify host properties, see the "User rights required to manage hosts" section of Required User Rights for Managing BizTalk Hosts and Host Instances.

You use the BizTalk Administration console to modify the following host properties:

  • Windows group. Members of the Windows group will have permissions to run the hosts instances of this host. When you select a Windows user group for a BizTalk Host, it is recommended that you create a new group that is dedicated to that host. If you do use an existing group, ensure that the group does not have more privileges than are needed. For more information, see Access Control and Data Security.
  • Host tracking. At least one host in the group must host tracking. This option indicates whether the host loads the BizTalk Tracking component to process health monitoring and business data.

    Note  It is recommended that you create at least one host instance of the tracking host. If there is no running host instance of the tracking host, the MessageBox database will continue to accumulate data with a subsequent degradation in performance.

    Hosts that host tracking have read/write access to the tracking tables in the MessageBox database, as well as access to the Tracking database. Therefore, any objects running in a host that hosts tracking also have read/write access privileges to these database tables. Hosts that do not host tracking have only write access to the tracking tables in the MessageBox database, and do not have access to the Tracking database.

    Any host marked as "host tracking" no longer uses the BizTalk Host group. BizTalk Administration automatically removes the BizTalk Host group from the SQL Server roles for the Tracking database. You must manually remove the BizTalk Host group from the SQL Server roles for the Configuration database and the MessageBox database. For information about removing a BizTalk Host group from SQL Server roles, see Removing a Host Group from a SQL Server Role.

    Note  Specifying a host to host tracking has an impact on the performance of BizTalk Server.

    Authentication trusted. You can specify that BizTalk Server trusts a host. BizTalk Server trusts authentication trusted hosts to place the sender security ID (SSID) on messages that the trusted host is queuing that map to users other than to the host. For more information about authentication trusted hosts, see Authenticating the Sender of a Message.

Host instances of trusted hosts and host instances of non-trusted hosts cannot use the same service accounts. If you want to change the trust setting of a host instance and the host instance uses a service account that other host instances use, you can do one of the following:

  • You can change the service account of the host instance for which you want to change the trust settings to a new service account.
  • You can change the service account of the host instance to an existing service account that other host instances with the same trust setting use.
  • You can delete the host instance, and re-create it with a different trust setting and service account.
  • Default host in the group. There must be a default host in the group at all times. The orchestration enlistment process automatically uses the default host to host the orchestration, unless the user explicitly selects a different host. The first host created is marked as the default host. For information about the default host, see About Hosts.

To modify host properties

  1. Click Start, point to All Programs, point to Microsoft BizTalk Server 2004, and then click BizTalk Server Administration.
  2. In the Administration console, expand the Microsoft BizTalk Server 2004 (local) node, and then double-click Hosts.
  3. Right-click the host you want to modify, and select Properties.
  4. In the <Host Name> Properties dialog box, on the General tab, do the following:
    Use thisTo do this
    Windows Group Type the local or domain group for the host.

    Note  The Windows group can only be changed if no host instances exist for this host.

    Host Tracking Select this check box if you want the host-to-host tracking services.

    Note  At least one host in the group most host tracking.

    Authentication Trusted Select this check box if the account under which the host runs should be trusted. For more information, see Authenticating the Sender of a Message.
    Default Host in the group Select this check box if you want this host to be the default host for the group.

    Important  You cannot clear the Default Host in the group check box. You must first select a new default host.

  5. In the <Host Name> Properties dialog box, on the Certificate tab, do the following:
    Use thisTo do this
    ThumbprintType the thumbprint of the public key certificate used to decrypt inbound messages for this host.

    The certificate thumbprint has the format HHHH HHHH HHHH HHHH HHHH HHHH HHHH HHHH HHHH HHHH, where H is a hexadecimal digit.

    CommentType any information that will help you remember the certificate you are using for this host.
  6. Click OK.
