AD DNS resolution Issue for specific Site

Hello Experts,
Currently I am facing issue for DNS Resolution.
I have 2 Sites
Site A(2003 R2 DC) & Site B(2008 R2 ADC)
my domain name is abc.co.in
and I have another forwardlookup zone abcl.com (mail.abcl.com/Dev.abcl.com)
I am able to resolve host recoreds for abc.co.in & abcl.com from site A
I am facing issue for Site B
unable to resolve A records for mail.abcl.com
when I am trying to resolve using
============================================================
nslookup mail.abcl.com 192.168.0.5 (Site B ADC)
getting below output
Server : adc01siteB.abc.co.in
Address : 192.168.0.5
Non autoritative answer :
Name : com.co.in
address : 192.254.185.209
Aliases : mail.abcl.com.co.in
==============================================================
mail.abcl.com - 192.168.0.11 (Actual Internal A record)
I want to know why this trying to resolve from external DNS (192.254.185.209)
your help / pointers will be appreciable
R Udeg

Is your settings for site B the same for site A in the DNS Server properties?
Did you make sure that UDP and TCP port 53 is open both ways?
Did you make sure all resource records have been updated?
Did you flush the cache/ scavenging happened?
Did you check the DNS forwaders and recursion?
Remember if a DNS server fails to resolve a name for which it is not authoritative, the cause is usually a failed recursive query. Recursive queries are used frequently by DNS servers to resolve remote names that are delegated to other DNS zones and servers.
Note: If you disable recursion on the DNS server, you will not be able to use forwarders on the same server.

  • [CC] How to perform a script "foo_beforeSave.htm" only for specific site?

    Since a long time I use a script for automatic text replacements which perform with each save command.
    The script sits in that folder:
    C:\Users\myusername\AppData\Roaming\Adobe\Dreamweaver CC\de_DE\Configuration\Commands\foo_beforeSave.htm
    It works for all documents of all sites.
    The source code (the regex rule is just an example) of the script you find below.
    My question:
    I like to perform a script like this only for a specific site.
    I'm not a programmer. So I don't know where to place the script to reach that target. Or how I have to edit the source code of the script.
    Is there anybody who could help me with that please?
    I would appreciate it a lot. Thanks

    Well, the posted script is a full working one.

    Therefore it is unimportant, which regex is in the example.

  • Safari can't find insert server Server DNS resolution issues

    I'm getting this error a lot.
    Most of mine are to .gov sites that change their DNS resolution fairly frequently
    Here is a list of the types of sites that often come back with server not found errors.

    http://farmingforum.co.uk/forums/index.php
    Further research has shown that the problem is that Safari has changed how it looks up DNS services between revision 5.0.3 and the one in Leopard as the problem never happened in Leopard.
    Clearing the cache does not help, clearing and resetting cookies does not help. Constant reloading of the page will eventually fix it, whenever Safari finally goes to the proper DNS.
    There is clearly a change in how Safari is looking things up on the DNS but no clue hot to change the behavior to get it back to the Leopard version that worked.

    If you use a router, does it have the latest firmware installed? Safari 5 introduced 'DNS Prefetching' (Safari looks up the addresses of links on webpages and can load those pages faster) which could strain some routers or modems producing a 'latency' in page loading. This was fixed in Safari 5.0.2, but you may see a benefit from getting a faster router or modem. You can read more about that here:

  • URL iview issue for intranet sites

    Hi Guys,
    I am creating a simple url iview for one of our Sharepoint site. when I preview the iview it works fine. but when I assign it to some Role, it doesn't load. "Page cann't be displayed" error comes. Some prefix with the text  "res://ieframe.dll/dnserror.htm#" added it the url.
    At the same time when I create url iview for internet sites they works. I have checked the Proxy settings and browser setting but no help.
    Please suggest if you something to try ?
    Regards
    Amit

    Hi Amit,
    Can you check the NWA Logs --> Default Trace to see if there are any log messages captured for this error. And analyse them.
    Also run a HTTP trace to check if the request calls generated. See if the Sharepoint URL is getting called or not. And status of response from that.
    Looking at the error, would suggest you to check the host names used on the URLs, should be FQDN.
    Also if your browser is IE8, may also want to add the portal and sharepoint domains to be shown in compatibility view. Can do this from Tools --> Compatibility View settings.
    Finally below is a help link to set up iViews in portal for sharepoint. Can refer to this and check the steps done at your end.

  • Internal DNS resolution issue - almost all external sites working

    I administer an Xserve running 10.5.8 Server. This client is running internal DNS due to a few internal services (iChat, mail, VPN, etc) - but his website, of the same domain, is hosted externally at a hosting provider. This is where I'm running into odd problems. For examples:
    ichat.company.com - 10.0.1.100 (when inside the network, also has FQDN on Internet)
    mail.company.com - 10.0.1.100 (same as above)
    www.company.com - xxx.xxx.xxx.xxx (the actual public IP address of the web server at the host)
    Do I need to do it this way? If I don't define the "www" record internally, and point it to the external IP of the hosting provider for the website, the clients inside the network can't see the website, because the internal domain services aren't answering the "www" question and won't hand off to the internet records. It's frustrating because every time the client has a subdomain added to his website, i have to add a record on his internal DNS or it won't resolve at his office. example:
    newdomain.company.com - xxx.xxx.xxx.xxx (public IP of the web host, or it fails)
    Is there a way to have internal DNS for a domain answer most but not all questions for the domain?
    - Bill

    Just as an aside, you could potentially setup a subdomain for the internal systems, e.g. 'corp.company.com' and setup the internal services in this domain - ichat.corp.company.com, mail.corp.company.com, etc.
    Then to get to the internal systems users use those .corp.company.com hostnames and the rest of .company.com gets sent upstream.
    It may or may not be sufficient for your needs. This kind of model works well for static users that only work in the office but may not work so well for mobile users.

  • DNS/LDAP Issue for Trusted Domain

    Hi
    I'm trying to configure  Configuration Manager 2012 R2 Forest Discovery to a trusted domain.
    Objects from the trusted domain (users/computers) show up in the Collections, but when I check under Administration\Active Directory Forests I can see Discovery Status "Failed to connect using default account" and Publishing status "Cannot
    Contact LDAP Server".
    I've added the SCCM server to local admin at the trusted domain via GPO and have also created the system Management container.
    When I check the log ADForestDisc.log I get this error message:
    "Failed to connect to forest X. This can be because of disjoint DNS namespaces, network connectivity or server availibility issue. Error Information The specified forest does not exist or cannot be contacted."
    I have setup Conditional Forwarders in DNS in both domains.
    I have also read other forums about this issue and should have the answer:
    "This error occurs for all of the domains that you mentioned and is typical when SRV records for DCs in those remote domains cannot be found. Forest discovery relies on DNS name resolution of SRV records to locate a suitable DC to communicate with."
    "The site server performing the forest discovery must be able to resolve the SRV records for the DCs or root domain of the other forest."
    We are using Windows AD integrated DNS in both domains.
    I'm not so familiar with DNS configuration so I appreciate if someone could tell more specific how to fix this.
    Thanks in advance

    Hi
    Thank you for your answer. This issue is solved. I've missed to open some ports in the router/firewall between the LANs.
    The status under Active Directory Forests is Succeded now, but when I check under boundaries, I can only see the "Default-First-Site-Name" site for the first domain (same LAN as CM Server) and I can only see the IP address range for that LAN.
    I don't Think  this is a big issue, but shouldn't the site name and address range for the other LAN (where the trusted domain is) be automatically found to during forest Discovery when I've checked the options to create site and ip boundaries automatically?

  • DNS Resolution Issues

    Hey Guys,
    I have recently set up a Mac OS X server at home and have set it up to work with the domain name server.geckocentral.co.uk for which I have created an A record and it works perfectly.. this is the Mac OS X standard tutorial method presented by the great Todd Otholff for accessing your network on an outside line and I followed it perfectly.
    The problem I now have is that I cannot access http://geckocentral.co.uk anywhere in the world although I could on and off earlier on but even off my WiFi my mobile devices can no longer access it so I guess the internal and external DNS are both broken ?
    When you add the domain to the servers DNS it has to hold the zone geckocentral.co.uk and then server.geckocentral.co.uk is the machine name within the domain.
    Is there perhaps a record I can add somewhere to tell the DNS that anything not assigned to server.geckocentral.co.uk needs to look somewhere else since my website is hosted externally with innohosting along with my webmail etc and now its busted.
    This is for my business I run and I am hoping there is a way to fix it.
    Regards,
    Matt

    You'll want to launch the following diagnostic command and confirm your local DNS is working:
    sudo changeip -checkhostname
    If you're referring to any DNS services off of your network and if you're using NAT as is typical, then the above command will probably report a DNS error.
    Here are details on setting up LAN-local DNS on OS X Server.
    I would generally recommend against using the same domain name both inside your firewall on your NAT'd network and outside via your DNS provider's servers — it's possible to do that, but you'll then have to track public IP addresses around within your internal DNS.   If I've guessed at the trigger for the issue you've encountered, it's involving two separate authoritative DNS servers, or there's no internal DNS running here. 
    Either use a subdomain of a domain you've registered or have permission to use, or use a seperate registered domain inside your network, or (getting more difficult as ICANN is adding new top-level domains) use a bogis domain such as .mattd25 as your top-level domain.  If you choose to use a bogus domain, do not use .local, .com, .net or any other existing top-level domain.

  • SharePoint 2010 Session issue for Internet site

    Hi,
    We have migrated one application from MS.net to SharePoint 2010. Session is used allover application. The issue is, when we are using this site from Intranet, session is working absolutely fine, but when we use this site over Internet, Session is getting
    null frequently for both FBA & windows authentication. 
    We have enabled session in web.config as below :
    <sessionState mode="InProc" timeout="600" cookieless="false" />
    & one more point i would like to add is, our internet site is on different port(extended port). We have cross-checked web.config from both port to resolve this issue, but nothing helped us out. 
    Please help..!!!

    Hello,
    Just try to enable session state in SP server. You may run below powershell command:
