After installing Windows Server 2003 Service Pack 1, the default security settings for MSDTC and DCOM must be modified to allow BizTalk and ZTP to work properly.

Change the MSDTC Security Configuration settings and DCOM permissions on each server the ZTP components remotely communicate (BTS, MIIS, SMS, SQL, WSS). Set the MSDTC settings:

  • Enable Network DTC Access
  • Enable Allow Inbound
  • Enable Allow Outbound
  • Set the Transaction Manager Communication option to “No Authentication Required”

Also, grant the service accounts for ZTP and the BizTalk Host (i.e. ztpservice and btsservice) ALLOW for default Remote Launch, Activation, and Call Access for DCOM on each server. Or, specify permissions for each component (ZTP/BTS/WMI) on each server.
