Resolving Single-Name Domain on DC

So I have a domain lets call it CONTOSO its a single-label domain name.
I can currently join computers to the domain but when you do an NSLOOKUP for the domain it doesn't resolve. Im trying to figure out if theres something wrong with the DNS settings since no client not even the DC can resolve the domain name via NSLOOKUP.
It also doesn't resolve if I add CONTOSO.local.
Is this normal behavior? I am planning a domain migration to corp.contoso.com to get it as a FQDN and I have been unable to setup a trust between them eventhough I gone through setting up secondary zones and conditional forwarders.
I think that there may be an issue with the forest dns records. If I run from the CONTOSO Domain Controller:
nltest /dsgetfti:CONTOSO
Geting forest trust information failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN
But running:
nltest /dsgetdc:CONTOSO
Works properly.
Any thoughts?

Hi Jorge,
Would you please run ipconfig/all
command on the DC, then post out the results for further analyzing?

Single Label domain names

Greetz!
I would like clarification on Single Label Domain names in SP 2013 web applications.
When I set up my A record I can set the Name, FQDN and IP Address. If I leave Name blank it will use whatever is in the FQDN?When I enter the FQDN I should use something like "Company.Local" or "SP.Company.Local" and not "Company"
When I set up my root Web Application, I will use the FQDN that I gave in the A record and I will not leave the ":80" on the end of it.
My intention is to setup a single web application and run HNSCs off the default zone. I will use Windows Authentication with basic Kerberos. I'll have a root site collection but we won't be using it.
Am I thinking straight about avoiding the use of single label domain names?
Thanks!
Love them all...regardless. - Buddha

"Single Label Domain names" has specific meaning and that applies to Active Directory (SLDs are not supported by SharePoint).
You will want to use an FQDN as your Host-Named Site Collections will be present underneath the root domain (e.g. if you create a Web Application using "root.company.com", your sites will be "portal.company.com", "teams.company.com",
as a couple of examples). Your Web Application will be created without a host name (see PowerShell example here: https://technet.microsoft.com/en-us/library/cc424952.aspx#section2).
Your "root.company.com", in my example, with be a path-based Site Collection as the "Root" Site Collection, which is required for all SharePoint Web Apps. That is described here: https://technet.microsoft.com/en-us/library/cc424952.aspx#section2b.
They use the WFE URL, but I prefer using the FQDN.
Another advantage of using FQDNs + SSL is that you don't have two different URLs for internal and external access, thus SharePoint Alerts will always have the correct URL, etc.

Single name space in between Exchange 2010 and 2013

Hi,
In my current environment I have 2 Exchange 2010 servers with DAG no CAS NLB. I installed Exchange 2013 with 2 CAS with WNLB and 2 Mailboxes with DAG. The main requirement is to configure Single name space to access in between Exchange 2010 and Exchange
2013. On Exchange 2010 DAG there is a URL using is owa.domain.com and I also configured in Exchange 2013 all the virtual directories with this name owa.domain.com but having an issue that when I open explorer and use the owa.domain.com URL the user on Exchange
2013 gets their mailbox but user on Exchange 2010 gets error HTTP 403 blank page.
I observed that in Exchange Organization settings CAS settings one server OWA, ECP etc shows their internal external URL but the other server unable to open the OWA, ECP URL and give error message that "An IIS directory entry
couldn't be created. The error message is Access is denied. HResult = -2147024891"
Please guide how to resolve this issue and use the same name URL in Exchange 2010 and Exchange 2013
Thanks,

Hi,
See the below brief:
User will connect to mail.contoso.com as his namespace endpoint. CAS2013 in Site1 will authenticate the user, do a service discovery, and determine that the mailbox version is 2010 and is located within the local AD site. CAS2013 will proxy the
request to an Exchange 2010 Client Access server which will retrieve the necessary data from the Exchange 2010 Mailbox server
Go through the full blog for better understanding of the redirection.
Client Connectivity with Exchange 2013
Hope you have changed your DNS records to direct connections only to your new Exchange 2013 server. You'll move the host names (for example, mail.contoso.com) users have been using to connect to Outlook Web Access, Autodiscover, and so on, from your
Exchange 2010 server to your Exchange 2013 server. When an Exchange 2010 user tries to open their mailbox, the Exchange 2013 server will proxy their request and communicate with the Exchange 2010 server on their behalf.
Configuring DNS includes the following:
Change the primary host names, such as mail.contoso.com, autodiscover.contoso.com, and owa.contoso.com (if used) to point to the external, publically-accessible, IP address of the Exchange 2013 Client Access server with your public DNS provider.
Change the primary host names, such as mail.contoso.com (or internal.contoso.com if you're using different internal host names) and owa.contoso.com (if used) to point to the internal machine name of the Exchange 2013 Client Access server on your internal
DNS servers.
NOTE- Go through the Exchange Deployemnt Assitant - Configure DNS Records section

Single Label Domain - Corss Forest trust issue!

Hello There
We have a single label root domain ex: "abc" trying to establish the external trust with the other forest's root domain which is FQDN ex: xyz.com. The trust seems to be working fine from abc to xyz.com however the trust from xyz.com to abc is an
issue.
We are not able to resolve/ping domain abc from xyz.com DC. We are able to ping DCs in abc from xyz.com.
On xyz.com DNS forwarder are pointing to abc DNS server and WINS has been configured to route to abc WINS. Everytime when I ping abc from xyz.com DC its pointing to some unknown IP.
on the xyz.com DC tried setting up the registry key AllowSingleLabelDnsDomain, updated the LMHOSTS and host file with abc domain but still unable to resolve the single label domain. We could not suspect that its an issue with the network as we are able to
ping abc domain DCs from xyz.com
Thanks in advance.

Hi,
It’s not recommended to use LMHOSTS file. Instead, we can use conditional forwarders or secondary DNS zones for DNS resolution between the
two forests. Besides, we need to open required ports for building inter-forest trust.
Regarding how to configure name resolution between two forests, the following article can be referred to for more information.

Cannot resolve host names on local network

It is a local network with router, few Windows computers with shared drives and one Mac.
Windows shares appear correctly in SHARED and can be used without any problems, like iTunes and iPhoto libraries are on those shared drives and work properly, even if ip address of those computers would change.
BUT - if I am trying to use VNC and connect to hostname:port, it says that server is not specified. If I try to ping hostname it says Unknown host.
At the same time, similar ping from Windows computer work without any problems.
It could be possible that router does not support something standard and communicates with Windows using something windows-specific, but what confuses me is that I can see computer names resolved in the finder already! Also, as I said iTunes and iPhoto can work with shared files on dynamic ip's which would be not possible if host names would be not resolved.
Thanks.

Domain Name Resolution for local IP addresses require a Local DNS server running on your network.
Bonjour names will resolve without a Local DNS server. So this is why iTunes and iPhoto works as they use bonjour technology.
A bonjour name ends in .local so in your macs sharing preferences you give the mac a name of imac its bonjour address is imac.local
Other than that you are best giving your devices fixed IP address and adding there hostnames to your hosts file.
the contents of /etc/hosts on your mac would look like
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
so at the above that you could add for example
192.168.1.5 mypc
192.168.1.6 myprinter
Then you could ping 192.168.1.5 by
ping mypc
So would have to add these entries to each hosts file on every computer on your lan.
Or you could setup a local dns server and give each computer on your LAN a fully qualified domain name.

TNS: could not resolve service name

ERROR: ORA-12154: TNS: could not resolve service name
does any1 know what this means...and how to overcome this problem
username : scott
passwd: tiger
host string: myora
i have personal oracle8i in d:\oracle
and d2k in d:\d2k
it connects with the SQLPlus
however with d2k when i try to connect it gives the above error
message.
does any 1 know a solution to the problem...

Hello,
First of all, If you are using PO8i and D2k as a front end
on single machine,no need of specifying Connect String. You can
connect using scott,tiger. If still it is giving problem,try
this one.
Open TNSNAMES.ORA file from folder NET80/Admin in your PC
using NOTEPAD. Look there entry for myora. If it is there,Check
SID,IPAddress or remove word "World" from there. See E.g
ora816 = -- Your connect string
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = 10.0.0.3) -- IP address
(Port = 1521)
(CONNECT_DATA = (SID = ora816) -- Database SID
Hope it will work...

Single Authentication Domain

Hi,
I am creating a new environment on PT 8.50 for Portal 9.1 with DB as Oracle 11G R2 on Linux OS which is on domain xyz.com and i have an old environment of portal8.8 on domain abc.com.WE are trying to provide a link from Portal9.1 to Portal8.8 which is on a different domain.Is it possible to establish a single authentication domain between them as both the domains are different?
Webserver being used is IBM Websphere
Thanks
Vijay

If I understand your question correctly, I think the answer is no.
You can't establish a PeopleSoft single signon relationship between a PIA site that's on domain xyz.com with one that's on abc.com.
Single signon requires PSTOKEN authentication to work, and browsers will not forward cookies across domains (this would be a security vulnerability), so this can't happen because the target site would never get a PSTOKEN cookie to authenticate against when clicking the link.
But you can do something like this:
site 1 = company1.corporation.com
site 2 = company2.us.corporation.com
If your names were set up this way, then you could set your cookie domains and AuthTokenDomain to .corporation.com and set them up with single signon links to each other. The key is what is the domain associated with the PSTOKEN at the time it was issued, and will it be allowed to be forwarded to and accepted by the other site?
Theoretically, you could also set up .com as the authtoken domain, but that would be really bad from a security perspective, because you would basically be allowing anybody on the Internet to send you a PSTOKEN.

MacBooks can't resolve printer name when sending job to windows 2008 R2 print server.

So I am work at company in a windows server 2008 r2 and we have a windows 2008 r2 printer server. Our macbook pros are not on the domain so every time we print to the server we have to type in our credentials.
MacBooks can't resolve printer name when sending job to windows 2008 R2 print server while on wifi but works when hard wired. Any thoughts? The error message I receive is "invalid printer name". I've tried adding the printer through the advanced tab in the print and scan tab of system preferences. I add it buy smb://servername/printername.
When I tried to print on the wifi at my office I get "invalid printer name" in the print job status que.
We can just do direct printing but I would like to know if anyone has had this issue before and if you could point me in the right direction. Thanks!

I assume you aare using exchange when configuring the email notifications? What I would do is just use a normal IMAP & SMTP account such as Outlook.com or if you use a POP connector for exchange, one of those accounts' SMTP settings.
For example, I have a POP connector installed and my emails are hosted at 1and1. What I would do here is put my 1and1 SMTP settings in and use these, instead of using Exchange.
Let me know if this is possible.

Unable to resolve machine names - Anyconnect

We have an ASA5505 configured for client and clientless VPN access. When using the AnyConnect VPN client, we are unable to resolve machine names without having to fully qualify the domain. For example, instead of specifying exchange we must specify exchange.domain.com. We can connect/ping using IPs. When using the Cisco VPN Client, we are able to resolve names just fine using only the machine name. Both connections show the same correct WINS and DNS servers. I'm not sure where to start looking to resolve this. Any ideas? Thanks!
Versions:
ASA 8.0(4)
ASDM 6.1(5)51
AnyConnect 2.3.0185

"Database Log In Failed - TNS could not resolve service name"

Hello.
I have an installation of Oracle 10g Release 2 (10.2) for Microsoft Windows (32-Bit) using WinXP Pro on my computer.
I have also installed the compantion CD on the same machine (In a separate home directory) so that I can use PL/SQL.
I have searched through the forum threads but haven't found any similar problem. The solutions that fixed other peoples problem don't seem to be applicable to mine.
I have created a user 'antagning' and some tables and also some PL/SQL procedures that compile fine. When I request
http://localhost:7777/pls/projekt/firsttest
(firsttest is the procedure. doesn't take any params)
I get the famous
Database Log In Failed
TNS could not resolve service name
Verify that the TNS name in the connectstring
entry of the DAD for this URL is valid.
This is my DAD file:
<location /pls/projekt>
SetHandler pls_handler
PlsqlDatabaseUsername antagning
PlsqlDatabasePassword antagning
PlsqlDatabaseConnectString ORCL
PlsqlAuthenticationMode Basic
PlsqlErrorStyle DebugStyle
</location>
and my tnsnames.ora looks like: (there is only one on the machine so there is no conflicting setups I think)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =
localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
finally, this is my sqlnet.ora:
# sqlnet.ora Network Configuration File: c:\oracle10g\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
I haven't set any default domain because the database runs on my local computer and not on a microsoft server in a domain. Is that correctly concluded?
I get an OK message when I ping my TNS with "tnsping orcl" (Maybe that information is not relevant in the context)
My webserver is started and is running fine (I think). If I request:
http://localhost:7777/pls/projekt (without any procedure name)
I get the message that no procedure is specified to run so I get some sort of answer from the webserver, so far so right.
When I log in using sqlplus with my own created user account I have to leave the database field empty or the login will fail. If I specify the field with the string orcl
the login will fail. Does that imply that something is not quite right? Maybe that hasn't got anything to do with the failure message.

Has anyone resolved the problems with using TNSFormat?
As is, I want to move to a shared server setup and to do that I want to use TNSFormat and point to a tns entry which is setup for IPC+Shared connection.
But the Oracle Home that has the Oracle HTTP Server (from the companion CD) does not have SQL*net installed and does not seem to understand TNS.
I have TNS_ADMIN setup, I have ORACLE_HOME_LISTENER poiting to the DB Home.
for the OHS home, using "sqlplus login/pw@ipcshared" works, but "tnsping ipcshared" does not, since tnsping does not exist in the OHS home.
I cannot install SQL*Net from the CD1, since it requires a dedicated/new home and does not want to install in the OHS Home.
The only format that works in a dedicated OHS Home setup is ServiceNameFormat.
Any help or input would be very helpful.
Regards
ps. This is a redhat linux setup.

Support for Single Labeled Domain

Question - When will Microsoft stop supporting "Single Label Domains"? Now with Windows Server 8 in the horizon, I would like to know if it will let you upgrade your current AD infrastructure if it is setup as a Single Label Domain.

I'm sorry, but I truly don't know. The reason that I don't know, is I've never tested it or let an AD infrastructure remain as a single label name for this length of time. I've fixed a number of them in the distant past with renames. I'm not aware of anyone
currently with a single label name until I saw this thread.
From what I see, I don't really think so if it hasn't caused any issues up to this point.
Besides, why do you want to bump the levels up? Is there something you are trying to introduce that requires the levels at 2008 R2? If it's DNS based, it may fail anyway due to the single label name, because the basis of the single label name is DNS *thinks*
it's a TLD, such as "COM," "NET," etc. That's why it's problematic. DNS is hierarchal and requires a minimum of a two level domain name.
So if you have a computer, called computer1, and your domain name is DOMAIN. Then the computer's FQDN is computer1.domain. But that looks like a domain name. Make sense?
Anyway, I'm sure you've heard this and read that in my blog. I'm curious ... Will you be planning on renaming your domain?

"couldn't resolve host name" error message

I have a new Z30 with the latest OS update installed and can’t connect to several Wi-Fi locations because of error message ‘couldn’t resolve host name’. Is there a fix to this as it seems to be an issue with BB and no other type of devices?

Assuming you're connecting via wifi, this would suggest your wifi connection is failing somewhere along the way.
Occasionally, my PB's wifi icon shows green and looks like it's working, but if I turn the PB wifi off and back on, it usually fixes the problem. You could also try rebooting the PB if resetting the wifi doesnt work.
If these things don't correct the problem, then check your wifi router (reboot it if necessary) and maybe check your internet connection with another device, ie home computer or whatever to make sure you're not having service issues.

IFS 9 : TNS:could not resolve service name

Hello,
I have this message when Trying to connect in Java to IFS 1.2 :
oracle.ifs.common.IfsException: IFS-21008: Unable to connect to
iFS service
java.sql.SQLException: ORA-12154: TNS:could not resolve service
name
I have been developing with IFS 1.16 for a while but now I have
to upgrading to IFS 9 (1.2). To set up my development
environment I did the same thing that I did for the version 1.1.6
1-     Copying all Jar from D:\oracle\ora90\9ifs\lib and I had
them to my classpath
2-     Copying the folders under D:\oracle\ora90\9ifs\settings
to have access to the IfsDefault.properties. file.
3-     I got the new JDBC driver and Oracle Client 9 on my
developer station.
IfsDefault.properties is pointing to the right TSN. When I test
my TSN (orcl) with the SQL+ it works just fine. I tried to use a
Invalid Ifs Service Name instead of IfsDefault too see if I got
a different error message and no, I got the same error. It looks
like the environment doesn’t find the IfsDefault.properties
file ?
Any Idea of it could be ?
There is the code that I use to connect :
LibraryService service = new LibraryService();
CleartextCredential cred = new CleartextCredential
(username, password);
ConnectOptions options = new ConnectOptions();
options.setLocale(Locale.getDefault());
options.setServiceName(repository);
options.setServicePassword(repositoryPass);
_ifsSession = service.connect(cred, options);
// Doit mettre explicitement le Admin flag dans la
Session
DirectoryUser user = _ifsSession.getDirectoryUser();
_ifsSession.setAdministrationMode(user.isAdminEnabled
_logger.info("user " + user +" is now connected to
Ifs " + repository + ", " + _loggedUserCounter + " connected.");
Thank you

Looks like your TNSnames is not properly configured .. Did you
try to do a sqlplus from the command prompt to see if you can
