Adding Host Instances in the BizTalk Administration Console

Administrators use the BizTalk Administration console or WMI to add host instances. Adding a host instance maps the instance of a given host to a BizTalk Server. If you have an existing host instance that you must repair, you can attempt to repair the host instance by adding it again.

For information about the user rights required to add a new host instance, see the "User rights required to manage host instances" section of Required User Rights for Managing BizTalk Hosts and Host Instances.

For information about using WMI to add a host instance, see MSBTS_HostInstance (WMI).

You must stop an existing host instance before you can re-add it. For information about stopping a host instance, see Stopping a Host Instance in the BizTalk Administration Console.

Note  If you want to create more that 26 host instances, you must follow the instructions in Knowledge Base article 184802, "User32.dll or Kernel32.dll Fails to Initialize," located at http://go.microsoft.com/fwlink/?LinkId=26176. If you require additional host instances after you apply the recommendations in this Knowledge Base article, you can try reducing the amount of memory available for each instance of the BTSNTSvc service. This will provide additional memory necessary to create more instances.

Note  The service account will automatically be granted "log on as service" permission on the server where the host instance is installed.

To install a host instance

  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 create a new instance of, click New, and then select Instance.
  4. In the Add Host Instances dialog box, select the server on which the host should run.
  5. In the Provide account information dialog box, type the logon and password information of the service account with permissions to access this server, and then click OK.
  6. Click OK.

After you install a host instance, you must start it so that it can route messages to the MessageBox databases. For information about starting a host instance, see Starting a Host Instance in the BizTalk Administration Console.
