Update Host Instance Properties
You can use the BizTalk Server Administration Console or Windows Management Instrumentation (WMI) to modify host instances. You can modify the service account running a host instance. You can also disable a host instance. For example, if you want to preserve the settings for a host instance and you do not want it to start, you can disable it. For more information about host instances, see Host Instances.
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.
You must change the credentials for a host instance by updating the properties of the host instance. If you change the credentials of the corresponding service, the service account you specify for the host instance must be a member of the group on the host. Do not use the Services snap-in or the Computer Management console to change the credentials of host instance, otherwise the host instance may not function properly.
If you change the credentials of a host instance, you must also change the corresponding SQL Server credentials. If you do not update the SQL Server credentials, the host instance will not function properly.
For information about using WMI to modify a host instance, see MSBTS_HostInstance (WMI) in the UI guidance and developers API namespace reference.
To perform this procedure, you must be logged on as a member of the Administrators group and the BizTalk Server Administrators group.
In addition, you must also be a member of the db_securityadmin SQL Server Database role and the securityadmin SQL Server Role on the server(s) where the following databases are:
BAM Primary Import (BAMPrimaryImport)
BizTalk Management (BizTalkMgmtDb)
BizTalk MessageBox (BizTalkMsgBoxDb) (all)
BizTalk Tracking (BizTalk DTADb)
Rule Engine (BizTalkRuleEngineDb)
We recommend that you update account information for host instances by using the BizTalk Server Administration Console or a Windows Management Instrumentation (WMI) script. This ensures that BizTalk Server can update the account information in the BizTalk Server databases and keep the security configuration between the databases and host instance synchronized.
Click Start, click All Programs, click Microsoft BizTalk Server 20xx, and then click BizTalk Server Administration.
