Cumulative update package 4 for BizTalk Server 2009

Microsoft released a new update package for BTS 2009. Cumulative update package 4 is now available here.


  • BizTalk Server EDI support: FIX: A TA1 interchange acknowledgement is not returned when you use a two-way receive port to receive EDI interchanges in BizTalk Server
  • BizTalk Server Design Tools: FIX: Visual Studio crashes when you build a project in BizTalk Server 2009 if message types are classes from a referenced .NET project
  • Microsoft BizTalk Server Adapters: FIX: “Error encountered while querying virtual server state for URL” error when you configure WSS adapter in BizTalk Server 2009

!! Important Note:
After you apply this cumulative update, the settings for the DTA Purge and Archive Job roll back to default. This may cause backlog in the BizTalk Tracking (BizTalkDTADb) database. It is recommended to re-configure the job. For more information, visit the following Microsoft Web site: How to Configure the DTA Purge and Archive Job
