DNS query

[mojo1979]

Hi,

I have setup dns but not sure if it is correct - in the dns mmc, under my domain name, i only have three folders: _sites, _udp, _tcp. I thought there should be a 4th, namely _msdcs? Is this correct? If so, it is missing in my dns....

Thanks

Not too sure, but you might want to get netdiag.exe and dcdiag.exe (just do a search on google). They should tell you if something is wrong.

 

[markdmac]

yes, you should have a folder _msdcs which should contain just a name server (NS) record for your DC with its IP.

I hope you find this post helpful.

Mark

ok, this is what i have....

Under Forward Lookup zones i firstly have -

A folder named _msdcs.domainname.com - under this i have gc, dc, pdc and domains.

I then have a folder named 'domainname.com' - under which i have tcp, udp and sites

I take it this is correct?

 

[markdmac]

That sounds OK.

Is your DNS AD integrated?

Yes, the dns is ad integrated

 

[markdmac]

OK, so next question is what makes you wonder if it si setup correctly? Are you having problems? Did you use the wizard to set up the AD on the DC?

I hope you find this post helpful.

Everything seems to be working, i.e. people can access internet, servers. I guess i am being paranoid because from past ewxperience I always remember there being this _msdcs folder. Perhaps in Server 2003 R2 it doesn't need to exist?

FYI, i created forward and reverse zones

I have also noticed that if i try to go to my company's website when I am within the internal network, that the website cannot resolve.

My domain name is mydomain.com
The website is

http://www.mydomain.com

I guess this is where the problem is....

 

[markdmac]

this is a very common problem that happens when you have named your AD the same as your public domain name. All you need to do to resolve this is create a host entry for

http://WWW and

give it the IP address for your web site.

I hope you find this post helpful.

[mojo1979]

so I create this entry under the main 'domain name' folder, not in _tcp, _udp or _sites?
Thanks again!

 

[markdmac]

Under the forward lookup zone. Right click and choose New A record. type

http://WWW as

the machine name and give it the IP of trhe web site. If you host the site internally, then use the Internal IP, otherwise use the public IP.

Thank you Mark, you've been a great help.

One last question - having my domain name the same as my website will have no effect if I am installing an exchange server correct?

Thanks

 

[markdmac]

None at all. Just make sure that your MX record in public DNS points to the public IP of the Exchange server.

Great thanks, just what I wanted to hear.

I've just noticed a strange dns related problem. When I am logged into the server I cannot ping either the IP or computer name of any of my users. I can ping my other servers.

However, from a users pc i can ping both the server name and server IP address...

Any ideas? (again....)

Cheers

Can someone briefly explain DNS/AD integrated.

 

[markdmac]

mojo1979, you most likely have the Windows firewall turned on at your workstations. This will block ICMP traffic by default and not allow your clients to respond to a ping request. You can alter the firewall to allow the ping response. You should also make sure that you have set the NIC to use NetBUI over TCP/IP if you want to be able to browse to machines on the network. You will find this on the DNS tab of TCP/IP properties.

trojanman, you are hijacking the thread, please post a new thread with your question. I suggest however that you first search support.microsoft.com as this is thoroughly explained there.

I hope you find this post helpful.
