SharePoint Portal Server May Stop Responding When Processing a VBScript Web Part (328311)


The information in this article applies to:

  • Microsoft SharePoint Portal Server 2001
This article was previously published under Q328311

SYMPTOMS

SharePoint Portal Server can create a VBScript Web Part. If a user creates a VBScript Web Part that uses the Microsoft OLE DB provider for Internet Publishing (Msdaipp.dll), the portal may stop responding. You must restart the SharePoint Portal Server services for the portal to start responding. The following sample code uses the Microsoft OLE DB provider for Internet Publishing:
Dim oConn 'As ADODB.Connection
Dim oRs 'As ADODB.RecordSet

Set oConn = Server.CreateObject("ADODB.Connection")
Set oRs = Server.CreateObject("ADODB.Recordset")

oConn.Provider = "msdaipp.dso"
oConn.Properties.Item("Prompt") = 4
oConn.Properties.Item("Flush WinInet Password Cache").Value = True

CAUSE

This problems occurs because the Microsoft OLE DB provider for Internet Publishing (Msdaipp.dll) is incorrectly adding a refcount to an object. When ActiveX Data Objects (ADO) calls to release all the objects, Msdaipp.dll still has an object that has a refcount. If Msdaipp.dll does not release the object, the critical section is not released. When the critical section is not released, the other threads must wait. If all the threads are in a wait state, the portal stops responding.
