Hi,
It sounds like this is the same issue?
https://knowledgedirectory.wordpress.com/2012/05/08/sccm2012-system-discovery-fails-when-configure-cm-discovery-settings/
Are you logged on with a local account on the SCCM Server when you run the admin console? try log on with a domain acount instead.

How Rock Guitar Legend Slash Hopes to Hack Music Discovery Apps

Editor's Note: What do you guys think about the concept of apps helping artists with music discovery? Does it have legs? Is it monetizeable? Read and then let us know your thoughts on this thread.--ks
http://thenextweb.com/insider/2014/03/10/sxslashathon-rock-legend-slash-hopes-hack-music-discovery (via TheNextWeb.com)
Glance at this year’s SXSW schedule and “Slashathon” might sound like an all-night 80s horror flick screening. In reality, the title is fairly literal: rock guitarist Slash is hosting an artist-focused hackathon on Wednesday with the hopes of drawing in crowds at the perfect mid-point between SXSW’s Interactive and Music sessions.
“It was an idea that came up when we were brainstorming the launch of our new record,” Slash, also uncommonly known as Saul Hudson, tells The Next Web in a phone interview. “I’m sure there are a lot of people out there who don’t have a platform to talk about new tech ideas for music, so we hope that the event helps inspire software developers to create something unique in the spur of the moment.”
Despite having been involved in several apps and video games, Slash says he’s not a particularly techie person, and is mostly interested in music recording apps that aid artists on the go. “I travel a lot, so tuner apps or things that enhance sound recordings are what I’m most interested in.”
A fan of Spotify and Pandora, the guitarist says music streaming apps are great for artists to both discover new music and share with fans, and he hopes to see more apps devoted to helping artists gain exposure.
“This is what people do now: they go to their computers and smartphones and find new music, shows, and artists,” Slash says. “Spotify and Pandora have definitely helped soften the blow on musical piracy… making records is a huge business now, and these apps help artists feel like they’re not doing it for nothing.”
While he doesn’t intend for the Slashathon to necessarily “solve” problems — as most startups tend to focus on — he would like to see music discovery become more catered to recording artists, not just consumers.
“I’d like to see the trend continue on apps that help artists get the word out about their new records and local shows,” he says.
It’s not surprising that a musician like Slash is keen on discovering new music. Thanks to Guitar Hero’s repopularization of “Sweet Child O’ Mine,” it’s hard to escape a dive bar or TV commercial without the familiar rock rhythms, even for Slash himself.
But of course, he’s grateful for the multi-generational love that’s passed along, decades after the song emerged.
“I was definitely more sick of it when we first wrote, recorded, and played it,” Slash says. “But over the years… it’s one of those things where you have to appreciate that a lot of people still like it.”
The SXSW Slashathon takes place at Capital Factory, and begins at 9 AM on March 12.

Unable to view the "Discovery Application" section under studio.

Hello,
I have installed OEID 3.0, using integrator I have loaded the sample getting started application to the server successfully.
I am following the instructions given under the getting started guide, after loading the data to the server I am able to login successfully to studio http://localhost:8101.
However in the login screen I am getting only the "welcome Admin Admin!" menu, under which I am unable to see the Discovery Application section.
But I followed the guide to access the control panel and change the default datasource, as per the guide I clicked "Back to home" but still Discovery Application section is not visible.
Which is obviously used for creating and managing the applications.
But I managed to create the application by selecting control panel > Portal > Application and I created the application and managed to load the EID_3.0_SampleApp.LAR file and able to successfully launch the studio.
Can anyone kindly let me know why I am unable to view the discovery application section till now?
Thanks.

I don't completely follow yet what you are seeing in your Studio instance. Is your "Discovery Applications" panel not showing, or is it empty, or is the "New Application" button missing? Perhaps you could paste a screenshot somewhere and link it here.
You say you are having problems with datasources - could you paste your data source JSON, and any error messages you are getting in the Studio logs?

Some Devices are not showing up at all in the Discovery reports

Hi all,
The first time I ran the CS device discovery I got 50 reachable devices. I scheduled the Device Discovery to be run every week. I added more subnets to the discovery but unfortunately the last discovery shows only 31 devices from the first discovered devices (50). I checked the DCR and there is only 44 devices out of the 50!
My question is:
Should not the scheduled Device Discovery discovers all devices -the previously discovered ones and the new ones-?
Why the rest of the devices are not showing up at all in the discovery reports (neither reachable nor unreachable) although all of them are pingable and responding to the snmpwalk tool from the CWLMS server.
Your kindly respond is highly appreciated.
Thanks in advance.

I ran the discovery again with the same settings after enabling debugging and I checked the following log files:
1. in the ngdiscovery.log I found a lot of errors all about Duplicate IpAddress example:
ERROR [DeviceManager : EvalTask-DiscoveryThreadPool-06 addNewDevice] : Duplicate IpAddress (127.0.0.51) found in addNewDevice().Device 1 ip = 10.8.113.29 , id1 = 127.0.0.51*F1COR.xyz.com*.1.3.6.1.4.1.9.1.283, Device 2 ip = 10.8.113.106 , id2 = 127.0.0.51*LCD.xyz.com*.1.3.6.1.4.1.9.1.283

2. in the CSDiscovery.log:
Error while changing the permission of the file C:\PROGRA~1\CSCOpx\objects\csdiscovery\1348\DiscoveryStatusObj
I checked the file and the casusers has a Modify permission
My Question is:
1. what is the meaning of those output exactly?
2. If CWLMS found duplicatedd IP address how it works in terms of (ignoring, updating existing devices, Adding the new devices, ... etc)
Many thanks for your help.

Visual Studio 2012: Can't access Sharepoint Web Services because of Discovery Credentials Prompt

Hi.
I've exactly the same problem that is descripted
here, so I'll add its description here.
My SharePoint is 2010
I am trying to access the web services that are located in this url:
http://<part_of_th_url_omitted>/_vti_bin/Lists.asmx. I have no problem accessing
this URL using my broswer, that is, when I type the URL and my browser's address bar and press enter, I can see the list of the services that are available. I encounter no problem by accessing this site through my browser at all.
However, when I try to access the services from that URL (http://<part_of_the_url_omitted>/_vti_bin/Lists.asmx),
a Discovery Credential Dialog box prompts me for my username and password. SO what I do is I enter my username and password that I used to access the sharepoint using my browser, the problem is, the dialog box doesn't seem to accept the username and password
that I enter as the dialog box is keep on appearing.
Below are the detailed steps on how I go about in adding the Web Services.
1. From the Solution Explorer, I right click on the "Service References" folder.
2. From the context menu that appears, I Click on "Add Service Reference...". The "Add Service Reference" Dialog box will appear.
3. From the "Add Service Reference" dialog box, I click on the "Advanced,,," button which can be seen at the bottom-left of the dialog
box. The "Service Reference Settings" Dialog box will appear.
4. From the "Service Reference Settings" dialog box, I click on the "Add Web Reference..." dialog box. The "Add Web Reference"
Dialog box will appear. This is the dialog box where I can type the URL of the service that I want to access. So I type "http://<part_of_the_url_omitted>/_vti_bin/Lists.asmx".
AFter typing that, I click on the Go button (which is the green arrow button at the right of the address bar of this dialog box).
5. After doing that, a prompt dialog box will appear which has the title "Windows Security" and it is aking for my username and password. SO
what I do is I enter the Username and the Password that I use in accessing the sharepoint site (http://<part_of_the_url_omitted>/_vti_bin/Lists.asmx)
6. The prompt seems to accept the Username and Password, but after that, a new dialog box appeared with the title "Discovery Credential" and
it says "The Service 'http://<part_of_the_url_omitted>/_vti_bin/Lists.asmx' requires a username and
password". SO what I do is I enter again the un and pw that I use to access the sharepoint site, the one that I used inm the previous dialog box.
7 After entering the username and the password and clicking the OK button. The dialog box reappears still asking for a username and a password, but this
time, it shows a different message. It says "The Service 'http://<part_of_the_url_omitted>/_vti_bin/Lists.asmx/$metadata'
requires a username and password". SO it really, what oonly changed is the URL, it has now the $metadata at the end. What do I do? I eneter the username and password again.
8. After clicking Ok again, the dialog box reappears, now it says "The Service 'http://<part_of_the_url_omitted>/_layouts/1033/error.aspx'
requires a username and password." Now it shows a very different username. Of ocurse, I still type in the username and password and click Ok.
9. after doing that, the dialog box reappears again and it shows the same message as in step 6. So I do steps 6, 7 and 8 in a loop.
10. When I finally get tired of entering the username and password, I click on cancel. The message box reappears again. So I click on cancel again. After
doing that, I can then, surprisingly, see the list of the web services. However, not surprisingly, I still can't use it because the "Add Reference" button which I need to click in order to use the Web services is disabled. So I can only see the list
of the services but I can't use it.

Hi Gaston,
I would suggest you the following thread, check whether it meet your scenario, it shows that if you have set IE options to remember the username and password, and you have enter wrong password before, this issue may happen:

Enabling network discovery on Windows Server 2012 R2

Good afternoon.
As per the title, I have set-up a new server at work. The server is running no problem but none of the other computers connected to the network can 'see' the new server. I've gone into the control panel and tried to turn on the network discovery, but it just
defaults back to 'off'.
I did so a search on here first before troubling anyone and I did find this answer :
Thanks for the post.
I did some research and found this issue may occur if the dependency services are disabled. Please make sure the following services are enabled and running.
- SSDP Discovery
- UPnP Device Host
Disabling Network Discovery/Network Resources"
That may well be the answer, but unfortunately that means absolutely nothing to me.
Is someone able to help me try and switch this on, but by offering an explanation an 'idiot' would understand.
Thanks in advance.

Hi,
This issue occurs for one of the following reasons:
•The dependency services for Network Discovery are not running.
•The Windows firewall or other firewalls do not allow Network Discovery.
To resolve the issue, follow these steps:
1.Make sure that the following dependency services are started:
DNS Client
Function Discovery Resource Publication
SSDP Discovery
UPnP Device Host
2.Configure the Windows firewall to allow Network Discovery. To do this, follow these steps:
Open Control Panel, click System and Security, and then click Windows Firewall.
In the left pane, click Allow an app or feature through Windows Firewall if you are running Windows Server 2012. Or, click Allow a program or feature through Windows Firewall if you are running Windows Server 2008 or Windows Server 2008 R2.
Click Change settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Select Network discovery, and then click OK.
3.Configure other firewalls in the network to allow Network Discovery.
4.Turn on Network Discovery in Network and Sharing Center

I'm trying to connect a BlueTooth headset to my Mac Mini. I can discover it, but soon after discovery it disconnects. Can't figure out how to reconnect. My only option seems to be re-discovery

I can discover the headset, but soon after discovery it disconnects. Haven't been able to figure out how to try to re-connect. And the help section titled "Use BlueTooth has absolutely no information on how to use it. All I can do is re-discover it. Every time I rediscover it, it disconnects shortly afterward. This headset works well with both my iPhone and iPad and has for quite some time. But it won't stay connected to my Mac.

Tried with another headset that works fine with iPhone and iPad. An LG HBS700. Same problem. It connects for maybe 10 seconds and then disconnects. So it must be a problem on the Mac. But this Mini is out of warrentee so taking it into an Apple store to get it repaired isn't a good solution. Maybe as a last resort.
Is there a way to select connect on the Mac? Everything else I've connected a BlueTooth device to has both a command for pairing and a command for connecting or reconnecting. I can't figure out how to select connect on the Mac.

Questions on asm disk discovery:

Questions on asm disk discovery:
1）What is the relationship btween asm_diskstring in the init.ora and DiscoveryString in the GPNP profile.xml?
2) Which one of the above two finally accounts for the disk discovery process?
3) We know that asmlib disks are self describing at the disk header. This overcomes the disk name/path persistency issue as we no long need to rely on the path to discover the asm disks, by setting asm_diskstring='ORCL:*' , ASM instance will identify the right disks automatically. However, I am not sure if setting asm_diskstring='ORCL:*' is the most economic way to do the discovery as I am not sure if Oracle will have to probe all the disks on the OS to determine the right disks. If Oracle has to screen all the disks in this way, then I think setting asm_diskstring='<path_to_asmlib_disk>' will be much faster, although this will be open to the persistent problem. Is my understanding correct?
Thanks.

From my understanding all disk you see in /dev/oracleasm/disks are the disks in your system that been discovered by asmlib at discovery stage.
Currently, due to bug 13465545, ASM instance will discover disks from both locations, ASM_DISKSTRING and gpnp profile, which can cause some mess in disk representation for asm. You can check the settings using asmcmd command: dsget, and set to be the same using dsset.
I think its more secure to set ASM_DISKSTRING to only the disks used by asm instance.
ASMCMD> dsget

Alert "An internal exception has occurred during discovery." related with Lync

Greetings All,
I'm facing this alert in one Lync 2013 agent. The problem is the SCOM agent is trying to execute a Lync 2010 PowerShell script in folder “'C:\Program Files\Common Files\Microsoft Lync Server 2010\Modules\Lync'” but this server is Lync 2013 so this folder
does not exist, due to this error is generated the alert.
I have recreated the SCOM health state folder in order to force all discoveries process, but the problem continues after.

Try adding the NETWORK SERVICE account to the following local groups on the Edge server:
RTC Component Local
RTC Local Administrators
Then restart the System Center Management service.
This fixed it for me. If you look at the membership of the equivalent local groups on a Lync Server 2013 Front End you'll see that these groups contain the NETWORK SERVICE account. Looks to be an oversight by MSFT.
Also you can refer below link, Same issue here

ITunes 11 Stops Responding to Bonjour Discovery Multicast Broadcasts, Why? This stops the the Apple TV 3 from being able to start a new stream from the home share and the iPad remote app can no longer see the home share too.

I'm having an issue where my Apple TV 3 and all our iPads periodically seem to loose connectivity to an iTunes home share on a Windows 7 PC. Using a network protocol analyser on the PC I have identified that the point of failure corresponds to the ATV3 sending a bonjour discovery request and getting no reply from iTunes. Why the ATV3 'forgets' where the home share is is possibly another issue but the root cause of the failure is that iTunes, or more specifically the mDNSResponder service, is not responding to the UDP multicast port 5353 broadcast discovery packet sent by the ATV3 or iPad. The mDNSResponder service does start responding again after iTunes is restarted thus making the home share accessible once more, however, this frequent drop out is unacceptable and often happens after only a single TV show has been watched from the home share making the solution unworkable for a family, we simply cannot be restarting iTunes constantly it ruins the user experience completely!
The nature of this failure indicates that the ATV3, the iPads, the host PC and network are all working correctly and the point of failure here is the lack of response to the bonjour discovery protocol with the net result of either a spinning 'connecting to home share' message or the home share just disappearing from the computers section.
If there is a configuration fix for this please let me know as I haven't located a fix! Otherwise this seems very much to be a code flaw in iTunes 11 or the mDNSResponder and I would appreciate some input from Apple! Going on other questions in these forums it would seem the problem is not limited to Windows PCs but also Macs too. NB: This is not a TCP issue, when the ATV3 or iPad knows the IP of the iTunes server all works flawlessly, it just periodically they seem to refresh the list of home shares and at this point they loose the information about the home share they have just been using because of the non-response to the UDP multicast discovery broadcast packet, that is arriving at the host PC and isn't being blocked by the firewall.
Many Thanks!

In my case there was no import from a former mac.
My problem (at least mine) is that no app that offers media sharing works properly. Neither itunes home sharing nor AirVideo nor EyeTV sharing.
So I'm pretty sure that this is network issue.
Adding another user on my mac and sharing a new library works not also. But sharing from another laptop in my WiFi works. So this has to be a network issue on my mac, not only my user, but an issue of the whole system.
But I'm not willing to reinstall MacOS X for that if I don't have to.

Multiple Discovery Systems on the same network

Is anybody successfully running more than one DS on the same network? We have edited the hostname of the DS but their still seems to be a conflict between the two servers and the SID names cannot be the same as well.

Hi Phillip,
The changing of the hostname is not recommended by SAP, but there is a customer who succeeded in doing so and claims to have even connected 4 Discovery Systems to the same network.
Knowing Maxim, I believe he indeed achieved it.
Read his blog: /people/maxim.efimov2/blog/2007/05/07/how-to-change-hostname-on-sap-enterprise-soa-discovery-system
My only tip: make a backup of the systems before you make any significant changes.

I replaced my keyboard batteries and the light is flashing so it is in discovery mode. But I am stuck on the home page where I need to type my password, without a keyboard. Aluminum trick didn't work. What do I do?

I shut off my computer and the next day replaced the batteries in my keyboard after getting the low battery message. After replacing them and turning the keyboard on and off the green LED was blinking which meant it was in discovery mode. The problem is I can't login to my computer because I need to type in a password. But I can't use the keyboard so I can't use my mouse to find the device because I can't login. The aluminum ball trick did not work and I did recheck the battery life and they are in the right way. How do I fix this?

Try resetting the iPod > iPod touch: Turning off and on (restarting) and resetting

LMS3.2 User Tracking IP Phones Discovery Doesn't Work

I am having difficulty getting the User tracking for IP Phones to work correctly in Ciscoworks LMS 3.2.
Callmanager is version 7.1.5.10000-12. Campus manager version is 5.2.1
The Callmanager publisher and two subscribers are all showing as application servers with green icons under the topology services view.
The callmanagers show as CDP neighbours on the switches to which they are connected.
I can do an SNMP walk of the ccmPhoneTable from the Ciscoworks devicecenter and get a ton of returned data.
The IP phones are discovered as end hosts and have mac address and IP address info when checked in the User Tracking utility.
Callmanager sysObjectID = OID: CISCO-PRODUCTS-MIB::ciscoMCS7835I
Any help you could give with troubleshooting would be greatly appreciated.
Regards
Rob

Thanks Nick,
I had seen that document and been through the processes
The mac and IP addresses of the ip phone are discovered.
The callmanagers are discovered and have green application server icons in the topolgy view
I can do an snmpwalk of the ccmPhoneTable OID and get returned data (as per this post by JClarke https://supportforums.cisco.com/message/664859#664859)
I can't do an snmpwalk of the ccmPhoneExtension as described in that document but I assume that since it applies to campus manager 3.2 and 3.3 that it is a bit dated and not relevant to later versions of callmanager.
I think that I have covered all the basic cdp/snmp and discovery issues. Any suggestions on where to go from here would be appreciated.

Rob

"Discovery failed to null" error message when starting up Oracle Management

hey folks,
i am trying to get the Oracle Enterprise Manager to work and i get an error message. Here is what i've done so far.
1. Installed Oracle service. It is started (under Start>...>Services it says "Started").
2. Created a Listener for the Oracle service via Net8 Assistant. It is also started.
3. Created a Service Name in Net8 Assistant listening to the above mentioned Listener. When i tested it, it said "test successfull".
4. Created an ODBC Data Source via the ODBC Administrator.
5. Created a repository for the Oracle service using the Enterprise Configuration Assistant.
so now i am trying to start the Oracle Management Server and when i click on "start service", a command window opens and the following is on it:
"OEMCTRL for Windows NT: Version 2.1.0.1.0
Copyright (c) 1998, 1999 Oracle Corporation. All rights reserved.
Starting the Oracle Management Server...VXA-3008 : Starting OMS Services, Wait.
[xxxxxxxxxx.ou.edu-DiscoveryThread][2003-11-20:11:9:26:765] Discovery of xxxxxxxxxxxx.ou.edu failed due to null
The OMS is now started and ready."
where xxxxxxxxxxxxxxx is the name of my machine. The status for the OracleManagementServer under Services is "Started", but when i go to the Oracle Enterprise Manager console and try to log in, it just locks up.
any ideas?
Thanks.

if you are getting connection to the OEM you have to choose if you get connect in STANDALONE MODE or OMS MODE.
if you choose the first you have to get connection as a
user that has granted sysdba role
if you choose the second you have to get connection as a
user called sysman or another user stablished for the repository.

HP LaserJet 400 MFP M425dn: bug in MTU path discovery, printer reboots via web interface

Firmware Datecode: 20121205
1. We can not access this MFU over VPN link. Otherer devices are accessed successfully.
As far as I understand there is an error in MTU Path Discovery.
tcpdump logs are attached.
Is there a way to change MTU of this device?
2. This MFU a reboots when I open page "Settings" of "Networking" submenu (/hp/device/set_config_networkSettings.html?tab=Networking&menu=NetSettings) if option "System" -> "System Setup" -> "Language" is "Russian". But this looks like a very good feature since I've have not found the way to reboot this printer remotely.
Here I was tring to access web interface over VPN (IPSec), 192.168.4.135 is IP of my comp, 192.168.160.200 - is IP of MFU, 192.168.160.254 is a gateway:

Its hard to understand what you are trying to do or ask here. We have some offices connected via IPSEC tunnels. IPSEC interface's MTU is 1280 bytes (not 1500 bytes as Ethernet). All other devices successfully work over this VPN link. HP m2727 works. HP m425dn does not work. As a network administrator I've traced source of problem on all possible points and found that HP m425dn has a bug in the "Path MTU Path discovery" routine. The logs I attached shows that any packet of the TCP stream that the printer (160.200) sends to host (4.135) has "Don't fragment" flag set. According to IP standard the router HAVE TO discard the packet with DF flag set and size bigger then MTU since it can not pass a packet further without fragmentation - IPSEC MTU is 1280 bytes only while HP sends 1500 bytes. The router informs the printer about this problem with ICMP message Type: 3 (Destination unreachable) with Code: 4 (Fragmentation needed) suggesting MTU of next hop: 1280. The router does not communicate with the printer itself, it just informs the printer about network problem. According to IP standard the printer HAVE TO resend this data with the size of packet decreased according to suggested size. This is expected behavior of the Path MTU discovery routine. But the printer sends the packet again with the same size and DF flag set. The router again discards the packet and informs printer... This cycle repeats again and again until connection is closed due to timeout. Therefore "Path MTU discovery" routine is broken at this device. It would not be a serious problem, but the printer resends packets at rate over 28000 pps (about 40 MBytes per seconds) and its CPU is so heavily loaded that it even does not respond to touches on its touchscreen. So an innocent attempt to print document on terminal server located at another office leads to inaccessibility of the printer.

HP Officejet Pro 8600 - Printer is on Network but not Discoverable with Typical Discovery Method

Hi all.
I need help! I have fought with this printer (HP Officejet Pro 8600) for about an hour. The error message I get says that the printer is on my network but is not discoverable using the typical network discovery method. I can set it up using the IP address (and will), but we frequently reset the router, and I don't want to deal with the printer everytime I do this. I figured it was something with the Windows firewall. I temporarily disabled it and tried again - nothing different. I am also running AVG free edition, but it does not have a firewall. Any help is appreciated! Forgot to add... I'm running Windows 7.

Hi Kelly,
The printer should be able to reconnect to the router by itself after the router is reset. Why do you have to reset the router? It might be part of the issue with the printer.
There are multiple ways for the software to discover the printer. There could be a setting in the router or even software services in the computer that are causing the normal methods to not work.
After you reset the router, does the printer not reconnect? The blue wireless light would continually blink if the printer cannot reconnect to the router after the reset.
I was an HP employee.
