Slow browsing within folders

Discussion in 'Server Networking' started by msnews.microsoft.com, Apr 11, 2008.

  1. Hello Everybody,

    I am facing a rather strange situation. I have setup an enviroment with a
    couple of servers one of which is acting as a file server. It is an HP
    DL-380G4 with RAID5 and Windows Server 2003 R2.

    The symptom is that even on the server console (since it is happening on the
    clients too) when you try to browse from one folder to another, sometimes
    there is a noticable delay. The symptom exists on the clients side too (Win
    XP Pro SP2) more often along with a long delay when they try to save, even a
    small word document.

    This server used to act as a DC, DNS, DHCP but after many tries to find out
    what is going on, finally I've removed these roles to another server in
    order to reduce the load. But unfortunately the problem still exists.

    The only role the server has right now, exept from the FS role, is that it
    has the Symantec System Center consoel for the Antivirus.

    I had enable folder Quotas but I've removed them hopping that would solve
    the problem. No luck!

    The server has two NIC's in a team and most of the folders storing the data
    are quite big (10 - 80GB).

    Any ideas or anyone have face anything similar?

    Thanks in advance

    Andreas

    We'll need configuration info to better assist otherwise it will be mostly
    guesswork on our end. Please post the following to help give us a start in
    diagnosing this:

    1. Unedited ipconfig /all from the server and from a sample workstation that
    is having this problem
    2. The AD DNS domain name
    3. Event log errors on both machines. Please provide the EventID# and Source
    name.

    Thank you,

  4. No actually the problem in occuring when I browse through the folders from
    Windows Explorer.

  5. The problem initialy was discovered from many workstations but it turned out
    that it is happening on the server console too.

    There are no event log errors on the server. Everything looks fine and thats
    the problem because I can not find anything to start from.

    The AD DNS domain name is ADKDOMAIN.local

    Ipconfig /all :

  6. Hello msnews.microsoft.com,

    What happens if you disable anything according to your AnitVirus and then
    try it again?

    Best regards

    Ok, that looks good so far. I also wanted to see one from the workstation.

    How about where that client is? Is in on the same subnet as the DC or on a
    different one? If different, are there any servers over there?

  9. No there is only one subnet. All PCs are geting the IP information from DHCP
    server based on the below IP info.

  10. According to the hostname it implies that this is a Domain
    Controller,...however in the TCP/IP specs it is not pointing to itself as it
    should be in the first DNS entry.

    That is all I see with what's infront on me right now.

    Good point, Phillip. I wonder how many DCs there are as well as the
    ipconfigs of the other DCs. If anyone of them is multihomed, this can cause
    a problem with resolution especially if the clients are using the other one
    for DNS.

  12. Yea, with this it looks like 3 DCs already.

  13. It used to be a domain controller, but in my effort to find a solution I
    removed all the roles of this server (DC, DNS, DHCP) in order to reduce the
    load. But again no luck!
     
    msnews.microsoft.com, Apr 18, 2008

  14. There are 2 DCs acting as DNS too.

    I was wondering if it would be possible, since the server has 2 NICs to add
    an additional CPU and split 1 NIC per CPU. Does anyone know if this is
    possible either from the OS or the NIC driver? I have a feeling that it may
    have to do with the network traffic/utilization although I have no such
    clear evidences.

  15. No.

    Even with an old slow half-duplex 10mbps connection your "folder browsing"
    would be almost instant. It is only the actual "file copy" of large files
    that would be slow.

    As far as I am concerned,...there is no way that "wire performance" of the
    network has anything to do with this. The problem is somewhere related to
    OS responsiveness. The OS is having to "wait" for something,..I just don't
    know what it is. It could be Nic drivers or the TCP/IP Stack, but that is
    as "low" in the model I would go,..most likely it is higher up in the OS
    "food chain".

    Is this Server 2003? Is SP2 applied?

  16. In
    Whenever a non-teamed multihomed server exists, especially if the two NICs
    are on separate segments, expect problems. However based on the ipconfig,
    the NICs are teamed.

    Are any of the DCs multihomed?

    I believe it is 'waiting' for resolution, but the server having two NICs.

    Also the other thing I can think of is if the clients are legacy clients,
    which would involve disabling SMB signing.

    For the original poster, here are my resources on 'slow' network
    performance. Evaluate each to determine if any applies to you based on
    scenario, operating system versions and conditions.

  19. Many, many, many thanks! I will check each one thoroughly.

  20. No, all DCs have two NICs in team mode.But the problem existed even when the
    same server was a DC.
