The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

We have a Windows 2012R2 Domain.  Our windows domain is xyz.com.  our website should be www.xyz.com.  We can access the website from outside of our network but not from within.  I've resolved this issue years ago but don't remember how I did it.  I know it's a DNS entry on the DNS server but can't recall what it is.  Feelin old!

Thanks!

When I ping a server it returns IPv6 IP instead of IPv4. I disabled TCP/IPv6 protocol, but it did not resolve a issue.
Found IPv6 in the DNS.
Remove IPv6 from DNS.

Now pings as IPv4. Couple days later same server pings as IPv6 again. I found IPv6 in DNS as well.

Hello,
I have a domain who's externally hosted website is the same .com extension.. so when someone on the domain types    domain.com they get the 403 access denied error (unless you prefix w/ https:// then it goes to unsetup web iis service)
The externally hosted website is www.domain.com
I created an A record in the DNS server for www to point it to the web host ip. However, now when you type in www.domain.com from within the domain, it resolves in the address bar as www.www.domain.com  .... How can I correct this situation?

I use free Whois domain lookup tool for finding domain names ownership information, registration data and much more.  This service is very useful. For it to check sites of business partners, sites at which purchases and any useful sites. This will help avoid Internet scams.
And I am interested in your opinion.

Hi

Our company website is currently not on Wordpress (3rd party custom CMS site), but our company blog is already on Wordpress. We use 2 different domain names to access them.

We want to rebuild our website using just Wordpress and we want to integrate the old Wordpress blog into the new installation. This is easy and we have tested (simple export from old blog and import into new Wordpress).

But we don't know how to keep the 2 domains functioning.

Current setup:
DOMAIN #1 > CMS SERVER
DOMAIN #2 > OLD WORDPRESS BLOG

New desired setup:
DOMAIN #1 > NEW WORDPRESS SITE
DOMAIN #2 > BLOG POSTS on NEW WORDPRESS SITE

It is true that users on DOMAIN #1 will be able to use the menus to navigate to the blog on the new Wordpress server - this is fine. But for odd historical reasons some Blog readers don't know about DOMAIN #1 and will continue to use DOMAIN #2. We don't want them to hit the homepage and be confused - we want DOMAIN #2 to point directly at the List of Blog Posts on the new server (and look like a separate domain still). In other words DOMAIN #2 needs to point to a subset of the site. We don't want to just do a domain forward to DOMAIN #1 if at all possible.

Is this at all possible?

Hi EE,
I've a DNS resolution issue as below and it's just happened recently.
My backup failed to connect to the NAS storage due to this issue.

When i nslookup nasb01.fish.com, I will get result:

Name:    nasb01.fish.com
Addresses:  57.x.x.x, 57.y.y.y, 57.z.z.z, 57.28.222.123

However, from the DNS server i couldn't find any host A record for nasb01.fish.com.

Tried to nslookup the IP, and the IP resolves as follow:
57.x.x.x = nas111.fish.com
57.y.y.y = nas132.fish.com
 57.z.z.z = nas27.fish.com
57.28.222.123 = nasb01.something.fish.com

Can you guide me how to troubleshoot this issue?
The correct resolution is nasb01.fish.com = nasb01.something.fish.com = 57.28.222.123

I am having trouble setting up reverse DNS. MY ISP is saying they have setup everything correctly but I am getting an error when I do a dig. BAD (HORIZONTAL) REFERRAL I have two CENTOS Servers setup with 6.6 and Bind DNS. I have the reverse DNS setup on both of these dns servers and I can access everything fine when I connect directly to 64.41.186.27 or 64.41.186.28.

Please let me know if anyone has any ideas.

I have set up Server 2008 r2 to be a remote session host for rds. I purchased a ssl certificate and linked it to RDS and bound it to the default web site in iis 7. I created an A record for the RDS address using the wan ip address.  I opened port 3389 on the modem since that's the port rds is set to use. I still cannot connect. Any Suggestions?

It's not first time I am installing AD server (2012) and connecting client to domain, but yes!! its the first time doing in AWS ec2 instances. The scenario is I have 2 instances, one with AD services installed and another in workgroup. I am trying to connect to the domain (adding the client to domain) but I face an issue with the error:

Capture.PNG
Have checked the following:

1. DNS Servers configured are same for both the instances.
2. Can ping the domain as well as the host(a.test.com)
3. NSlookup seems successful
4. DNS Resolver cache cleared and tried again
5. Checked to see whether srv file exist in the location it says, it exist.

Can someone please support me where would be the issue.? Any ideas would be really appreciated.

We are trying to find a way to redirect our main site traffic at www.nextcrew.com to www.flipcrew.com without changing the address in the browser. We have our main site hosted on a rackspace server and the wordpress site is hosted on godaddy.

It is important to note that we do not want any redirection to take place for other subdomains like customer.nextcrew.com.

Is this possible?

Hello,

I have a machine which have two different hostnames but corresponds to the same IP address. In the user's machine, I see hostname1 when I check in properties, but in some other console (name cannot be disclosed) I see hostname2 for the same IP address. Hostname2 is pingable but not hostname1.

I did ipconfig /flushdns and ipconfig /registerdns , but it did not get resolved to one hostname.

Could someone please help me out with the steps to get only one hostname instead of 2?

Thanks in advance!
