LMS 4.2 discovery does not resolve hostname

Hi,
I'm trying automatic discovery with Ping on sweep module. I'm using the following configuration (you can also see it in the attached file):
discovery module - ping on sweep
global seed device - 192.168.6.35
preferred DCR display name - DNS resolvable hostname
The LMS server has its hostfile populated with the device ip/hostname that i'm testing with and resolving from the server works in both directions. Nevertheless, after discovery proccess is finished, the device is added in DCR with its IP address as dispaly name (screenshot in the attached file).
I've tried the same method in CiscoWorks 4.0.1 and it works fine.
I'm attaching the debug log files from discovery test. The LMS is running on Windows Server 2008 standard
Please advice,

LMS 4.2.2 Fault manager does not resolve hostname for some devices

This is Cisco Prime LMS 4.2.2 on Windows 2008 R2
As far as I understand it Fault Manager need to be able to do reverse lookup for ip adresses to show the correct name in the "device name" column. I have double and tripple checked and all devices that only is shown as an ip address do have a reverse in the dns used by the LMS server.
The device is correctly registered and inventory have been run. If I hold the mouse pointer over the crosshair on the row of the offending device all info is shown including correct device name and fqdn.
The server is upgraded from 4.2.1 to 4.2.2 and we have the same problem before the upgrade.

The problem may occur if the lookup was not possible when the device was added to fault management.
Faultmanager, unlike the rest of LMS, does not update the display name.
If the resolver.pl in /opt/CSCOpx/bin is able to get the device name, then resolution is fine.
The only workarrounds are to the delete the device from LMS and re-add it, or use cli tools on the server to remove and re-add the device from the DFM repository.
Cheers,
Michel

"The hostname does not resolve to any configured address..."

I think this is a stupid question But I just can't remember what I'm missing. It's been a while since I set one of these up.
I have just installed Lion and Server on a Mac Mini 2.66GHz C2D
I'm not trying to change the Open Directory settins from Standalone directory to an Open Directory Master.
When I do it saks me to create a directory adminstrator account. No problem. But when I hit continue on that screen I get a message saying:
"The hostname does not resolve to any configured address. Please ensure your hostname and network configuration is correct."
Now, I think this is because I haven't set up any DNS zones yet. But I'm not sure about that...
So can anyone(s) help me with these two things:
1. Is the Open Directory master I'm trying to set up dependent on setting up DNS first?
2. If so, can someone tell me what I'm supposed to do in the DNS, because for the life of me I can't remember anything about it.
I'll be very grateful for any help...
Thanks!
David.

Hi again. Thanks for the help. So that clears up that mystery. However...
Ok, so as already noted, I've completely forgotten how I set this up last time, but I remember that I still have an archive of my old Snow Leopard server before I upgraded it to Lion.
So I've fired that up in Server Admin to see how I set up the DNS in that, and see if that can remind me how to set up the same on my new Lion server.
I believe I've set it all up correctly, but alas, I'm still getting the same error message when I try to create the open directory master. So I must be doing something wrong still. I just wish I knew what that was.
I've attached screen shots of my settings. If you or anyone else can tell me what I'm doing wrong, then again, I'd be grateful!
The routing is done by my Airport Extreme, with the .200 IP address being assigned by DHCP client ID. The IP address of this machine is in fact 10.0.1.200. These settings are exactly the same (with one exception) as my (working) Snow Leopard server and just to be clear I'm not trying to run both servers at once!
The one exception is this: The first line in the screen shot says "1.0.10.in-..." (from the non-working Lion server), whereas on my Snow Leopard server, the same line says "200.1.0.10.in-..." Everything else is the same. I can't seem to see any way of "correcting" that. Is that the cause of the problem? And if so, how do I fix it? If not, what *is* the problem?
Thanks!
David.

Device discovery does not work with Yosemite

After updating to Yosemite, my (13-inch late 2010) Macbook Air can no longer find the printer on my home network, although I can print by specifying the printer’s IP address. Furthermore, Airport Utility cannot find my Airport Extreme; it says Device Not Found while acknowledging that the Airport Extreme was previously part of my network. However, the same Mac has no difficulty connecting to the internet through the Airport Extreme. It seems that some device discovery protocol (Bonjour?) is no longer working on that Mac.
I updated our other Macbook Air (11-inch mid 2011) to Yosemite without any issues. It finds the printer on the network, and Airport Utility finds the Airport Extreme.
Any suggestions?

Hi, this is Detective Vdawg, and I came across a similar issue when I updated to Yosemite on my MacBook Pro (Retina, 15-inch, Early 2013). Here is what I did. First, turn off all bluetooth devices turn off your printer and your computer. Wait about 15-30 seconds, then press and hold these four buttons for five seconds: shift, control, option, and the power button. What that does is refresh the hardware components; your settings will remain the same as they were before. After the computer reboots, then everything should be working the way it normally does including your device discovery. If that helps, please let me know; also let me know if it does not resolve your issue for whatever reason. I will be searching for different ways to resolve this problem. If you come across any more issues along the way, I would be happy to help you if I can.

I Ipod class wont play TED and other video podcasts. The genious bar could not figure out the problem. This problem is not isolated to a single computer. Secondly, the convert to ipod version feature in Itunes does not resolve the problem.

My Ipod classic wont play TED, The Grid, Techzilla and other video podcasts (but not all video podcasts). The genious bar could not figure out the problem. Instead, the Apple store gave me credit towards a new classic, which produced the same problem. This problem is not isolated to a single computer. Secondly, the convert to ipod version feature in Itunes does not resolve the problem. Lastly, I tried restoring the ipod to no avail. I've heard this is a video codec problem.

2008 R2 DNS does not resolve external websites until I clear DNS cache

Do I need to apply this hotfix

Thank you for posting the ipconfig /all, but we can't use it since the relevant data that we need to evaluate has been blocked out. I can understand if you have a strong security policy.
The Conditional Forwarders shouldn't be causing you to not to resolve specific domain names.
How long has this been going on?
What exactly occurs? Does DNS stops totally responding when you test it with nslookup, or are you just testing it with Internet Explorer?
If you have nslookup tests and responses, it may be helpful to see them, but if your security policy prevents you from posting them, I understand.
I'm curious about this part that you posted:
> "And as suggested by microsoft
> earlier,we have blocked few DNS
> Domains by creating conditional
> forwarders , pointing to
> our another domain."
Did you open a ticket with Microsoft support that provided this suggestion? If yes, you can email your support engineer that assisted you.
Or did you post this in this forum or elsewhere that you received this suggestion? If a forum post, do you have a link?
Without specifics, it may be difficult to assist. However, what I can provide are the following hotfixes. The second one you had already installed. I suggest and recommend to install the others.

TextLayout.swc does not resolve to valid file

Hi, I have not worked in Flash for awhile and have spent way too long just adding a link to a simple button. I have scoured the web looking for AS3 button examples and tried them all. No matter what I try, I keep getting the following error when I publish. When I try to click the link in the swf on my html page it doesn't link to anything and just goes back to the collapsed state of the flash file.
Here is the error:
Warning: Library path "$(AppConfig)/ActionScript 3.0/libs/11.0/textLayout.swc" does not resolve to a valid file.
Perhaps I should mention that I am currently evaluating Adobe Cloud versions, trying to decide if I'm going to be purchase the membership. Not sure if that matters but thought I'd mention it.
Thanks.

Thanks for the response. I actually shouldn't have any text fields at all (which is another reason I thought it was a strange error). I'm using an expanding ad template with a library that only consists of only graphics. I don't see any text fields in symbols or movie clips at all. I was looking to try to set it back to Flash 9 but it doesn't look like that is even an option with Flash CC. The farthest back I can go is 10. Hmmm. Kind of stumped at the moment.

I tried doing dozens of undo edits of the last 10 or 20 changes. None of them work. None of the suggested fixes work at all, either.
Worse yet, I can tell that my code is not what is looks like. It is not running the code that is on the diagram, it is running some previous version of the code.

insane object error.PNG ‏12 KB

Hi Greg,
Thanks for your reply. It sounds like you've been on both ends of a serious error/crash resulting in code loss before.
As Murphy's Law would have it, it happened right before quitting time.
I decided to stick it out & make it a late night while I remembered most of my changes.
I quit & restarted LabVIEW, pulled the VI from a backup done the day before, opened up the backup version of the VI, opened up the bad code, and tried pasting changes in. However, I soon got oodles of "insane object" errors, and gave up on this route.
I quit & restarted LV, opened up the backed up VI, opened the bad new VI on a 2nd monitor (after configuring the display etc.), and manually re-drew (i.e., "re-wrote") all my code just by inspection.
This worked. (To play it safe, I also forced a system backup before going home, and saved lots of revs. along the way during my edits.)
I rarely have experienced "insane object" errors in my 10+ years of LabVIEW programming. Therefore, I have used little of other languages the past 10 years, and have developed so much re-usable code that I know well, I don't want to move away from it. It is quite unsettling / scary when it happens, especially on a large program. It makes me consider going back to text-based programming, where at least there's some inspection of all but the most messed up files (vim/binary mode, for example).
Anyway, I am on my way now, but will be even more diligent about "Save As" to save interim versions during long code writing sessions.
Also, I ran chkdsk per Apps Engr suggestion on a ticket I did later open after doing this post.
Thanks, Matt

Discovery does not remove deleted objects

Well,
another issue with discoveries.
We are running discoveries via datafile:
The discovery DataSource script reads the datafile and creates the objects.
That's very nice and works perfectly.
Added entries in the datafile are discovered on the next discovery cycle.
Unfortunately if you delete some entries from the datafile the discovery does not delete the objects in SCOM.
Discovery's datasource writes a logfile and the deleted entries from the datafile are really no longer discovered
( I'm happy that reading files is a reliable function...).
So for this cycle discovery data contains some objects less than before.
But this new discovery does not lead to a deletion of no longer existing objects.
As a workaround we put these superflues objects in maintenance mode.
Would be gratefull if somebody has a good solution
regards
sebastian

Please run "Remove-SCOMDisabledClassInstance” from the Operations Manager PowerShell
console.
You might get some errors after running this. Errors are about the ObjectIDs and RuleIDs, but you can ignore those errors and should keep running this command until it completes successfully.
After completing successfully, the deleted objects will be removed the discovery and SCOM.
Hope this helps.
Thanks, S K Agrawal

DNS Server does not resolve new generic Top Level Domain names- CNR configuration issue?

Hi all,
I am not sure if this is the correct community to post this question, but I will give it a try. I noticed that the users of my network cannot resolve web sites using new top level domain names, like ".education", ".international", etc. I have an internal DNS server made by Infoblox and a Cisco CNR v6.3.3.1 as an external DNS server. Infoblox uses CNR as its forwarder and CNR uses the root DNS servers for queries.
I would think that CNR was the problem because it is an obsolete product but after speaking with a fellow engineer at another organization where they still use an older version of CNR than mine, they have no problems at all. So now I am thinking it is a setting either on Infoblox, or on CNR I need to change. I can see Infoblox is forwarding the requests to CNR but that's about it. I am not sure if CNR is discarding the request. When I do an nslookup from a PC in my network it does not matter if I set my DNS server to be the Infoblox or the CNR. Neither resolves the URL.
Then again, no matter what I lookup using the CNR as my DNS, I only get a response with the root DNS names and IPs!
Any help is appreciated!

Hi Constantinos,
Have you taken a look at the infoblox community site? We've just reposted your question there and alerted some internal SMEs that should provide a solution soon.

Sharepoint does not resolve users from federated AD directory

Our sharepoint farm resides in a domain called abc.com and we just federated with another domain def.com.
The issue is that 9 out of 10 times sharepoint does not resolve users from def.com when adding them using the normal GUI and people picker. Users from def.com domain will have to click on the url and request access before they can be added to the sharepoint.
Please can someone let me know what needs to be done so that sharepoint can resolve users from def.com domain using the people picker.
Kind Regards
Louis
thanks

Here is the way to do this via PowerShell:
http://thesharepointfarm.com/2014/01/powershell-for-people-picker-properties/
Do you have a two-way trust enabled? In that, case, it isn't required to use peoplepicker-searchadforests. If you do have a two way trust in place and SharePoint has port access to the remote domain controllers, does the remote domain NetBIOS and FQDN match
(e.g. EXAMPLE and EXAMPLE.com)?
As far as the credentials, you put in the remote domain's credentials, e.g. "forest:abc.com;forest:def.com,username,password" where the username is the sAMAccountName of a user in the remote domain.

Installing ios 8.2 does not resolve Google map navigation problem.

I have tried to install both of them lots of times but in each case I receive the same in my XE.bat file:
Instance created.
DIM-00019: create service error
O/S-Error: (OS 1387) Unable to add or remove a member from the local group because this member does not exist.
Have checked OS 1387 error at Microsoft Support and as possible cause of the problem they give as follows:
This issue can occur if the environment has a disjointed namespace (i.e. the domain has different NetBIOS and DNS names). For example, assume that the domain has a NetBIOS name of "domain.com" and a DNS name of "domain-old.com." When users are added in the Windows UI, they are displayed in the format of domain\ComputerName. However, you notice in the error log that there was an attempt to add a computer account in the format of domain-old\ComputerName. (System Center 2012 R2 Data Protection Manager install fails and generates ID: 4323: "A member could not be added")
Tried to find out my DNS name, but it is impossible because I don't have any domain installed and my machine is not connected to it. Some other blog (Install Oracle 11gR2 on Windows) advices to work with adding my computer account to some non-real windows domain (just for the purpose of resolving the network) as well and reinstall the database then. If I undestand it right I need minimum 2 machines for this. But I own just one, where the server is based and thought that is enough to run the database... no idea ..
