We upgrade BizTalk 2006 R2 to BizTalk 2009, upgrading SQL Server 2005 in-place to SQL Server 2008 at the same time.

The BizTalk admin console is excessively slow. After making some change (say, adding a receive port), just refreshing the view can cause a timeout error:

BizTalk Server 2009 Administration Console

Failed to load Group [ServerName:BizTalkMgmtDb] data providers. (Microsoft.BizTalk.Administration.SnapIn)


Failed to load Group [ServerName:BizTalkMgmtDb] data providers. (Microsoft.BizTalk.Administration.SnapIn)

Instance of the WMI class is not found. (WinMgmt)

BizTalk Server cannot access SQL server. This could be due to one of the following reasons:

  1. Access permissions have been denied to the current user. Either log on as a user that has been granted permissions to SQL and try again, or grant the current user permission to access SQL Server.

  2. The SQL Server does not exist or an invalid database name has been specified. Check the name entered for the SQL Server and database to make sure they are correct as provided during SQL Server installation.

  3. The SQL Server exists, but is not currently running. Use the Windows Service Control Manager or SQL Enterprise Manager to start SQL Server, and try again.

  4. A SQL database file with the same name as the specified database already exists in the Microsoft SQL Server data folder.

Internal error from OLEDB provider: "Timeout expired"

or sometimes the internal error is:

Internal error from OLEDB provider: "[DBNETLIB][ConnectionOpen (PreLoginHandshake()).]General network error. Check your network documentation."

Sometimes, just expanding the Applications node, I get this error:

Exception has been thrown by the target of an invocation. (MMCEx)


ExecuteReader requires an open and available Connection. The connection's current state is connecting. (System.Data)

Any suggestions as to how I can debug this?

These errors appear to have been caused by "Shared Memory" being disabled in SQL Server.

(Run "SQL Server Configuration Manager". Under "SQL Server Network Configuration" open "Protocols for [Your Instance]")

Edit: I was wrong. This seemed to help at first, but I continued to see similar errors elsewhere. And it appears that the Shared Memory protocol may actually lower BizTalk's performance (according to the install doc.)

I never figured it out. I ended up re-installing everything rather than upgrading.

I hope someone still has a better answer.
