NETWORK problems with WINDOWS 7

[Otto]

To all:

I do have problems with WINDOWS 7 against WINDOWS 7 or 2008 SERVER.

This is my test environment.

I am connected with MSTSC to the server where I copy a file to a folder.
(if I copy the file from the local PC to the server folder there is no problem!)

On my WINDOWS 7 PC I run the attached test.exe.

I check the for the file. I takes from 3 to 7 sec. till the test – program gets notice.

Could someone please make a similar test?

Thanks in advance
Otto

Here is a short video to demonstrate the behavior.

    oTmr:Deactivate()
   
    aDirServ := directory( "r:\itouch\bills\" + "*.dbf", "D" )

      if len(aDirServ) > 0
msginfo(   UPPER( aDirServ[1,1] ) )

        endif


  oTmr:activate()
return nil

To all:
I made the same test program in VB6 too.
The results are the same as with the (x)harbour test program.

To all:
Please help testing – more and more users switch to WINDOWS 7.
If there is a special netork setup necessary we have to fine this.

Could someone please report his test results.

Thank you so much for your help.
Best regards,
Otto

VB6 code!!!!

Private Sub Form_Load()
     Set fso = New FileSystemObject
    Timer1.Interval = 300
 
End Sub


Private Sub Timer1_Timer()

    Dim cLockDatei        As String
        Timer1.Enabled = False
        cLockDatei = "r:\itouch\bills\" & "test.txt"

        If fso.FileExists(cLockDatei) = True Then
           
            MsgBox ("file ok")
       
        Else

        Timer1.Enabled = True

Otto,

I tested your xHarbour example, as well from Windows 7 to Windows 7 and from Windows 7 to Windows Server 2008.

I don't have any problem.

A few weeks ago, I had an indexing problem with Windows 7 to Windows SBS 2008 (which is always 64-bits).

Have a look at this topic about this problem : http://forums.fivetechsupport.com/viewtopic.php?f=3&t=18851.

Maybe, this is the problem on your network too. Try to disable SMB 2.0 on your server and on your Windows 7 PC. Maybe, your problem is solved then.

Good luck.

Hello Maurizio, hello Michel,

thank you for your help.
I will test with SMB2 disabled.

Michel,

Did you test running the program on WINDOWS 7 client and make the changes inside the folder from within 2008 Server?

As from XP and mobile 6.1 the changes are seen within milliseconds do you think to disable SMB2 is also necessary
on the server.

I opened a support case with Microsoft. I get at 2.o’clock a call. I will report what the Microsoft support is suggesting.

Best regards,
Otto

Otto,

I did a lot of tests from Windows 7 to Windows Server 2008 and since I disabled SMB 2.0, I didn't have any problem anymore.

The SMB 2.0 problem only refers to Windows Vista, Windows 7 and Windows 2008. For XP there never was any problem.

Thanks.

Michel,
do you have a description – or a link where I can find a description - how to disable SMB 2.

Thanks in advance
Otto

Otto,

This links describes how to disable SMB 2.0, on th 64-bit server as well as on the Windows 7 or Windows Vista PC's.

Good luck.

Michel,

I disabled SMB but now I can’t get net access any more. Is there something special to follow?

Best regards,
Otto

Hello Michel,
I restarted the system again and now all is working.
I only changed the SERVER registry. Now speed is the same as with XP.
Best regards,
Otto

Otto,

Thanks but no thanks. I was glad to be somewhat helpful to you.

Have a nice weekend.
