Computer not file sharing

  1. I have two computers, both XP, a PS3 and a Roku soundbridge on my network.
    One of the computers seems to like to stop sharing over the network for some reason. I've posted with this same issue, on this same computer in the past, but what worked then is not working this time.
    The computer in question rarely gets used.
    I can ping each computer back and fourth sucessfully, and this computer does show on "workplace computers". It also appears on LELA as being connected.
    However, it does not appear to be sharing media to the PS3 and the roku. I have done all the obvious checks and making sure sharing is enabled, both computers are in the same work group and so on. There have been no changes that I am aware of, and the only firewall running is windows built-in.
    any suggestions.

    Is "file and printer sharing" checked under exceptions on the windows firewall?

    PS3 and Roku require the Universal Plug and Play service is started and running.

    Click Start->Run, enter services.msc. Find the Universal Plug and Play. Set StartupType=Manual to start on demand. StartupType=Automatic start immediately on boot. You must reboot in any case for change in StartupType to take affect.

    Check it's status=Running

    And to start troubleshooting File Sharing itself on XP, see this link to start out.

    The sucess of PING only says that TCP is correct on all the devices,
    ie: other things still need to be resolved.

    Solve the issues one at a time;
    • get file/print sharing correct
    • THEN address the PS3 & Roku issues
    Solving (a) will resolve workgroup names, file share settings and the firewall issues.
    The firewall(s) on all systems need to allow ports 138-139,445 in both directions.
    This should then allow a share to be accessed (assuming the password is correct).

    For the PS3, see this for the necessary ports

    For the Roku, you need to explicitly Share the device on the system to which it is attached.
    Open My Computer, find the device, right click->Sharing

    Unshare the share reboot and reshare!

    In services set Computer Browser, Server and WorkStation to all be started Automaticly.

    Also turn off all power management and Hibernation.

    Hi again, bpallgeier :wave:

    I thought your user name sounded familiar... and, in fact, it should! You're in fact the user where the issue of uPnp and SSDP came up in the first place! (i now see from going back and looking at your old posts)

    Am i correct from your quote that everything starts out OK? But after some amount of time it's just the one computer that stops "wanting to file share"?

    As if that is true, (it starts ok but eventually seems to stop) I think mflynn is right on track to the answer: Is a good chance the problem is related to power management settings on the problem computer.

    Try the following:
    Control Panel->Power Options
    => Under Power Schemes, set Standby to NEVER
    => Under Hibernation, DISABLE it

    Then
    Click Start->Run, enter devmgtm.msc to open Device Manager
    => For your network adapter, rt click Properties, Under Power Management tab, DO NOT ALLOW THE COMPUTER TO TURN OFF THE DEVICE TO SAVE POWER

    Reboot and let us know if problem persists. (i.e. Starts OK but eventually stops sharing)
    And if problem persists (or my guess at symptoms are wrong to begin with) please provide a bit more detail in just what sequence actions/types of error messages (if any messages) you are seeing

    btw... a handy freeware Network Monitor tool you may, in general, find useful is Look@LAN. If only to report on devices it finds currently connected (i.e. "pingable") on your network (aside from it being able to do more)
    => A device must respond to pings for the monitor to report it on your LAN (tho it will still report open ports if you scan the IP address)

    I've had this issue in the past with my beloved linux hacked xbox's, and one individual computer on my network. As mlflynn says above, my temporary solution to this is to unshare and reshare a directory, this somehow resets it and gets it working again, though usualy the problem creeps up again later

    And to Clarify my statement on Hibernation,

    Do not turn off hibernation on a Laptop.

    It is ok on a single personal Desktop computer. But not on a work a day computer (business or file sharing).

    Hibernation is generally OK the problem is that as is well known, some problems caused by misconfiguration, Malware or permissions etc cause Hibernation not to wake up as it is supposed to.

    If this computer is mainly only there to share its resource then if there is a power management hibernation issue it may not wake up.

    Sometimes it takes Keyboard or mouse activity to wake one with these issues up. And in some cases several clicks or key hits to do it!

    you might just find that power management is the root cause of it all. (in the past i've traced some network issues back to power management. eitehr the computer went to standby or hibernate or windows powered down the LAN card to save power. Whcih even tho may work when woken back up i've seen take several minutes with some cases)

    /* EDIT */
    But i have also seen cases where reboot is needed. (was a LAN card issue.. i'm guessing in its firmware)

    mflynn Newcomer, in training Posts: 2,793

    Yes! In the meantime the attempted connection to the share times out!

    Just thought of something else!

    Go to the NIC in Local area connection under Connect using click Configure to the right of the Network Adapter, then Advanced and lookat the Wakeup settings here.

    Then click power Managment Tab on the end. Here uncheck Allow the computer to turn off this device to save power.

    Hey guys,

    Thanks for the replies.
    I tried disabling power management as described above, and had no luck.
    What happens is, this computer (we will refer to it as #2), will stop showing its music and picture libraries to the Roku and PS3 after some time. Since I do not access the libraries from this computer as often as I do from computer #1, I am not sure when it decides not to share anymore. #2 is my wifes computer, therefore they are her music and pic files.
    The last time this happened, I was able to type "regsvr32 upnphost.dll" into the RUN box, and it worked, up until maybe a month ago.
    Both computers are desktops, not laptops, so I made sure power management was disabled on both.
    All services that should be running, are, and file and print sharing is checked in the firewall exceptions.
    It is not imparative that I resolve this, just more a matter of whats causing it?
    Computer #1 has never had this happen, Knock On Wood!

    Look in Windows Event Log.
    => In particular, System and Application Logs
    => Look for Errors and Warnings that have occured between the time the system was booted and the time "file sharing stops"

    Also, review any events (including Information events) from event source Service Control Manger (SCM) which would be reporting service start/stop/control information.

    btw.....another handy freeware tool to optionally check out Windows Event Log Explorer. Provides a nice interface around the Window XP inteface along with additional functionality that can be helpful when trying to use the Event Logs for troubeshooting

    /* EDIT */
    Could clarify when you say
    Are you saying
    1. File file sharing from computer #2 hasn't worked at all over the last month? (and i assume that then means even after a reboot)
    2. Over the last month, you boot computer #2 it works for awhile, you can no longer file share and the only way to get file sharing to work again is by rebooting (i.e. regsvr32 upnphost.dll no longer helps)

    Sorry, Its not working at all, and I am not sure when it stopped, description #1 above sums it perfectly.
    Since I don't always use my PS3 or Roku to stream music now that it's winter, I really don't know how long it has not been working again. That's what is so frustrating about it. I do not make many changes on computer#2, so I can never say, "oh, I just installed so and such, and it stopped working".
    On the other hand, I install and run tons of "crap", mess with settings, etc on computer #1 and it always works, go figure!

    Sure did, no luck there either. Tried it twice just to make sure and even rebooted.

    When I go to the download page for this, it's in a different language.
    And when it finishes downloading, my anti virus "detects a potential threat", so I did not install it. Is there a different link,safer?
  19. LookinAround

    LookinAround TechSpot Chancellor Posts: 8,276   +150

    1. Ooops. It's from an Italian company.
    • i must have picked the Italian language link. i'd fix it right now but RCN, my service provider, is giving me grief at the moment (i suspect they've been working on the servers the last few days.
    • Have been using this tool for years so certain any AV report is false positive but always only download what you yourself want to
    • I will also look for SAFE download site (like CNET) as i know some download sites (that certify no virus) also provide for downloads (and in English!) ;)

    2. Aside from Windows Event Log there's a very hand tool we could use to spot system change that's part of XP SP3 (I forget if you're running XP SP2 or SP3?)

    /* EDIT */
    1. You can also download Look@Lan from MajorGeeks or CNET downloads
    (i was going to provide a couple of screen shots for anyone reading but now my imageshack connections are hanging!)

    hum; interesting
    just installed an ran Look@Lan on my XP/Pro-SP2 system with all lan system running.

    1) it did find all systems, including the primary router to the ISP as well as a secondary to another subnet.

    2) it also reported bogus 'Active Services':
    1. port 3128 -- squid-http
    2. port 8080 -- http-proxy
    these are bogus (ie false positives) as verified agains Cports by www.nirsoft.net which
    has proven accurate over many months of use.

    Use the tool but understand that probing systems is a real 'black art' :)

    OK, I think I may have figured it out again.
    It ended up being a DRM isssue of some sort. I deleted the DRM folder and all of its contents, rebooted and presto, computer #2 started sharing again. I do not have any DRM protected files on the computer, but it seems to have worked. Now all I have to do is remember this so next time I don't have to bother you guys with it.
    Thanks for all the replies.

    Congrats. And thanks for the update.

    You might still find it interesting to look in your Windows Event Log (if you haven't already) if only to see if in fact any footprints left behind about DRM or Services or something else related to file sharing is there (so you'll also know to look for same events logged anytime future)

    But, in any case, is never a bother. Feel free to post anytime

    Windows Change Diagnostic Tool and Additional tool info to note

    This is the tool i was referring to a couple posts back. This tool makes it easy to look back and find when/what system changes were recently applied to your computer. You may find it quite helpful for problems in future It appears from your old thread you are still running XP SP2? Well, good news. You can download The Windows Change Diagnostic Tool for use with XP SP2!

    Excerpted from the MS KB
    hi jobeard

    can follow-up with some info (click on thumbnails for full view)
    • I certainly agree with your statement about "the black art" of probing systems (for ports, etc.) as well as having great results using Cports
    • Admittedly, I use Look@LAN most often to provide a convenient graphical view of devices on my network when I'm having an issue (vs. relying on it 100% for port scanning). Issues such as
      • Adding a new network device or
      • Seems to be a problem with an existing device falling offline
      [​IMG]
    • And to point out, try a rt click on a scanned port in Look@LAN provides other options (e.g. connect via telnent can be handy)

    And some additional tools worth noting
    • Cports
      As you note is excellent: easy to use and probably meets the needs of most people reading
    • Zenmap
      • For those of you with some knowledge of network ports (jobeard: i know you have a strong network background. Don't know if you've used Zenmap yet. An interesting tool!)
      • And would like to see detail on what can be found via port scans (local or remote) as well as anyone wanting to learn more about networking ports! Checkout Zenmap. It's a graphical interface to a command line port scanner Nmap
      • The Zenmap user interface can look challenging (and it can be if you want to start creating your own custom scans) but recommend one starts by using its Wizard. Let the Wizard build the scan commands for you. You can also start by using its predefined scans you can change via the pulldown you;ll see
        [​IMG] [​IMG]
    • There's another cool tool that probes ports and then reports the application using the port based on the network data footprint when it probes the port vs. assuming the app based simply on any standard network port definitions (but i gotta go find it somewhere on my machine.:D i don't recall it's name off-hand. Will provide an EDIT later

    hmm; concerned with Look@Lan

    I just found it also installs
    C:\WINDOWS\iun6002.exe
    which has been reported as a KeyLogging tool :confused:

    regedit contains only one enter; that with the Uninstall of Look@Lan, which implies
    the application has to explicitly launch iun6002.exe

    I've elected to disable Look@Lan

    Caveat Emptor,
    Jeff
