    SLP problem

    Hello,

    I have a strange problem.

    On my Netware 5.1 server, the novell client 4.90SP2 and novell client
    4.91SP2 clients have a serious problem. If a pc is booted, the user is able
    to login and contextless login finds the context.
    But if the user logs-out and restarts the desktop, he is not able to login,
    message "cannot access tree". If the users browses for the tree, it is found
    by SLP, but the context cannot be browsed without the "cannot access tree".
    If I put the ip address of the server in stead of the treename, user is
    able to login. Also if users wait for around 5 minutes,everthing works fine
    again and the context can be browsed again.

    I have configured SLP on the server "unscoped", the slpda is running and
    shows all the information needed. SLPINFO/D and SLPINFO/ALL on the problem
    workstation shows all information.

    The problem gets worst when I enter the ipaddress of the server as a static
    SLP Directory Agent.

    Who has any idea how to resolve this?

    Re: SLP problem

    I've often seen this issue resolved by "Disabling Spanning Tree" or enabling
    "PortFast" on the user's Port Switches.
    This helps the network ports initialize before timing out trying to get the
    SLP Info.

    Spanning tree is not running on the switches. Also the bad address cache
    timeout has been switched off, to test, same result...

    Re: SLP problem

    ZENFAN,

    Lets gather some more details about your environment...

    Any additional components of the client installed?

    Was Windows installed from scratch, a custom image, or an OEM image?

    Windows Event logs showing anything unusual?

    Security or any other driver-based software like firewall, VPN, remote
    management, antivirus, etc. installed and running?

    Can you verify a virus, spyware or some other corruption has not affected
    Windows? I've used these utilities in the past to help troubleshoot and
    they can tell you wonders about what is really going on with Windows...

    AutoRuns, Process Explorer, Filemon, Regmon, and LoadOrder
    http://www.sysinternals.com/

    DriverView and ServiWin
    http://www.nirsoft.net/utils/

    You might also consider getting a network trace looking for any unusual
    traffic...

    Can you post the SLPINFO /ALL output when it's working and when it's
    not working ?

    Re: SLP problem

    More info about the pc's affected.

    The pc's are Windows XP SP2, Novell Client 4.90SP2, no nmas and ZFD 3.2.
    components installed. Also the Contextless Login tool from coolsoultions is
    used. (LGNCL). Pc's have McAfee Virussscan 8

    SLPINFO/ALL shows that the DA is UP, also on machines that are not logging
    in. On the problem machines even start -> run \\serverip is not bringing up
    the nwgina for logging on, after login locally with administrator. Strang is
    that when IPX is added to the client, everything works fine (even after
    reboot).
    The problem only arises when the machine is rebooted after login on to the
    Novell Server. The first login is going fine, so SLP works. If you click on
    the tree button, SLP finds the tree, but when browsing for the context,
    "cannot access tree" appears. If I wait for around 5 minutes everything
    works fine.
    I thought it was a licensing problem, but then ipx client would also not
    able to login (nlstrace shows no errors).

    I have checked:

    1. Run complete scan on the pc for virusses and spywar -> no result.
    2. Update NIC drivers -> No result (also tested with nic fixed on 100Mb Full
    and Half-Duplex)
    3. Update to Netware Client 4.91SP2 + Connectivity patch -> no result
    4. Removed workstation manager on the client -> No result
    5. Checked if spanning tree was running on the switches -> No result
    6. Upgraded firmware on all Hp Procurve switches and turned off Lacp -> No
    result
    7. slp debug turned on -> no errors
    8. Show slp services and attributes and slpda -> everything is there
    9. Switched of virusscanner on workstation and server -> no result
    10. Back Name cache of on Novell Client -> No result
    11. Wait Before Giving Up On DA: 60000 -> No result
    12. SLP Cache Replies = 5 minutes -> No result
    13. Dsrepair (full unattend and local) -> No result.
    14. I ran a sniffer and see the following:

    Workstation = 12.12.4.41 and server: 10.12.0.1

    When It goes wrong: this goed on and on:

    I dont know what to look for further on, I think there is something
    seriously wrong with slp, but what. The Nw51sp8 server is fully patched
    (tested even the latest beta patches for winsock e.d.)

    Re: SLP problem

    I have several clients (meaning client businesses, each with 10-50
    workstations) experiencing the exact same problem - on Netware 6.5 SP3,
    SP4 and SP5. I am doing some research today before opening an incident
    next week. I am a CNE and do have SLP configured correctly. It is
    maddening - power off the computer for about 10-20 minutes, and it works
    again. Most noticeable right after a restart (for an XP update or
    something). Sometimes a power off, and restart works fine, other times it
    doesn't.
    SLP looks good from the workstation, I also have DNS configured correctly.

    I hope a solution is found soon!

    Re: SLP problem

    You still didn't post what I asked. All I need is the

    Re: SLP problem

    In addition to the SLPINFO /ALL, please post the
    DISPLAY SLPDA from the server listed as 'UP' at
