Etapas para reproduzir o problema

1. Crie um novo projeto Standard EXE.
2. Adicione um módulo para o projeto.
3. Copiar e colar a seguir declara e tipo no módulo: (Observação: se você adicionar isso para um módulo de formulário, verifique todas as entradas particular.)

4. Adicione dois CommandButtons ao Form1. Esses serão Command1 e Command2 por padrão.
5. Adicione o seguinte código para Form1, substituindo um nome de compartilhamento válido para "\\nome_do_servidor\nome_do_compartilhamento":
   

         Option Explicit
   
         Private Sub Command1_Click()
         Dim NetR As NETRESOURCE
         Dim ErrInfo As Long
         Dim MyPass As String, MyUser As String
   
         NetR.dwScope = RESOURCE_GLOBALNET
         NetR.dwType = RESOURCETYPE_DISK
         NetR.dwDisplayType = RESOURCEDISPLAYTYPE_SHARE
         NetR.dwUsage = RESOURCEUSAGE_CONNECTABLE
         NetR.lpLocalName = "X:" ' If undefined, Connect with no device
         NetR.lpRemoteName = "\\ServerName\ShareName"   ' Your valid share
         'NetR.lpComment = "Optional Comment"
         'NetR.lpProvider =    ' Leave this undefined
   
         ' If the MyPass and MyUser arguments are null (use vbNullString), the
         ' user context for the process provides the default user name.
         ErrInfo = WNetAddConnection2(NetR, MyPass, MyUser, _
         CONNECT_UPDATE_PROFILE)
         If ErrInfo = NO_ERROR Then
           MsgBox "Net Connection Successful!", vbInformation, _
           "Share Connected"
         Else
           MsgBox "ERROR: " & ErrInfo & " - Net Connection Failed!", _
           vbExclamation, "Share not Connected"
         End If
         End Sub
   
         Private Sub Command2_Click()
         Dim ErrInfo As Long
         Dim strLocalName As String
   
         ' You may specify either the lpRemoteName or lpLocalName
         'strLocalName = "\\ServerName\ShareName"
         strLocalName = "X:"
         ErrInfo = WNetCancelConnection2(strLocalName, _
