Can you please advice how to fix this problem

Thanks
Praveen

Private Sub ConnectFTP()
        Try

            'Setup ftp and connect.
            _ftpConnection.ServerAddress = Config.FtpServer
            _ftpConnection.ServerPort = Config.FtpServerPort
            _ftpConnection.UserName = Config.FtpUser
            _ftpConnection.Password = Config.FtpPassword
            'This setting is not working, the event is still firing based upon the default of 4096 bytes.
            _ftpConnection.TransferNotifyInterval = 1000

            If Config.FtpPassiveMode Then
                _ftpConnection.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.PASV
            Else
                _ftpConnection.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.ACTIVE
            End If

            ApplicationLog.Log("FTP Passive mode: " & Config.FtpPassiveMode)
            _ftpConnection.Connect()

            If Config.FtpFolder <> "" Then
                _ftpConnection.ChangeWorkingDirectory(Config.FtpFolder)
            End If

        Catch ex As Exception
            If _ftpConnection.IsConnected Then
                _ftpConnection.Close()
            End If
            ApplicationLog.Log(ex.ToString)

        End Try

    End Sub

The ERROR I get is:

The bolded bit is repating several time so I have deleted that repeating bit from the log file.
So how do we enable the Process performance counter, so the requested operation cannot be performed.

The application runs perfectly on WIN XP, but NOT on WIN 2003 server.

I have checked the registry, on XP, the Disable Performance Counters at the following location, has a zero value.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance

on the WIN 2003 server, there is no Disable Performance Counters property at the same location
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance

For one thing you've got a number of IP addresses for your server: 123.221.340.249, 122.122.343.249, and the server is returning 128.121.240.249.

Figuring out the correct one will help a lot.

Actually I have changed the IP addresses, just was not to sure if I could post them on the public forum,

Can you please advice how to solve thid problem.

thanks

Changing the IP addresses to differing ones wastes our time tracking down problems that don't exist. Next time just change to XXX if you are sure they are all identical.

The best thing at this point is to email your full log & and your code to support at enterprisedt dot com and we'll take a look and report back to the forum later.

support2 · Answer 7 · 2008-05-28T02:15:53+0000

It looks like this is your problem:

System.InvalidOperationException: Process performance counter is disabled

We don't really know anything about this error - take a look at this link for some advice:

http://www.dotnet247.com/247reference/m ... 55103.aspx

Perhaps you may need to remove the code that causes this exception.
