DNS server Help

I already have a dns server in window platform for window lab. I am planning to create a open directory for mac lab consisting of 20 mac pro. Do I have to need a separate dns server in mac server or I can use the dns server from windows.
I really appreciate any help.

Successfully running your own Open Directory server requires working DNS. However, there's no requirement that this DNS server be running on your open directory server.
Therefore you're welcome to use your existing DNS server, as long as it has all the associated forward and reverse records for your server you should be OK.

Mac mini server networking and DNS setup help

Thanks in advance to anyone who can help me with this. I'm working at a small business where I'm the only guy with any IT experience at all, but I'm new to Macs and OS X (<1 year) and being a server admin so please bear with me.
We just bought a Mac mini server as we are expanding from a bunch of workstations and Google Docs. I've just gone through the installation process, but nothing else is on the server, no user data at all, so if the answer is to reinstall from scratch, I can do it.
We'd like the mini to be a file server, print server as well as the gateway for the internet. I realize we could stick to our router and have the server as another node in the network, but we also got a Time Capsule for backing up the server and will locate it in another room to be another wireless access point there.
When going through Server Assistant, I didn't really know what to name the machine so I used corp-Server.local for the Current Hostname and corpserver.private for the DNS Hostname (though i actually use a 3-letter company acronym instead of "corp").
However, i realized after setup we'd want to access the server externally by name, so I changed the DNS hostname to server.companyname.com in the Zones tab of the DNS section of Server Admin (edited primary zone name, changed Nameservers entry for both primary and reverse zone).
I don't know what else I need to do though because there are loads of instances where corpserver.private still shows up, like in the Open Directory section of Server Admin (which btw always hangs when I open it) and the Contact Info of users (eg. user email is [email protected]). I also had trouble earlier using Server Preferences and Server Admin either not connecting or not recognizing my login, but that seems to have abated.
I guess my problem is, where else do I change the DNS hostname? Or do I have to change the DNS hostname back to corpserver.private (in Server Admin)? That way, I think at least everything will be consistent, but would I be able to still configure it somehow so that externally, we could access the server by the server.companyname.com URL?
Also, can the mini be a wireless router for the office? As mentioned before, we want to cut the existing wireless router out and use the mini instead (and use the Time Capsule as a wireless bridge).

So the ISP<->router connection can have a dynamic IP address, but the router<->server one should be static? I guess that means I have to set the IP address in the router. I hope I can get access to it. I don't suppose it matters which one I set first?
An IP router does not assign addresses.
A DHCP server does assign IP addresses upon receipt of a DHCP request from a client.
Some routers (and many firewall routers) do include a DHCP server.
A box with a static IP address does not need to send a DHCP request; it has a static address.
You'll need to ensure that the IP address pool within the DHCP server does not overlap the addresses that are manually assigned to your local hosts; the static IP addresses on your LAN.
[Here is an overview of the pieces involved here, and some of the typical terminology|http://labs.hoffmanlabs.com/node/275].
I hate to belabour the point, but I just want to clarify: in my setup where ISP<->router<->server<->clients, where the server is the only machine connected to the router, which one should be the local DNS server? The server, right? So if the DNS server is turned on in the router, I should turn it off? Or do I need both (ie. router for its LAN (to server), and server for its LAN (to clients))?
So to confirm, the configuration includes (probably) a modem, a router (firewall) and a router (Mac), and then the rest of the (local) show? That is not the simplest configuration, and it's Particularly given that Mac boxes make expensive and slow routers.
The usual configuration is ISP>firewall>LAN and the LAN is usually built from WiFi, wired connections and switches. Within one subnet (which is typical) any host inside your firewall is connected on the LAN, and can communicate (directly) with any other LAN client. The firewall is configured as the gateway; that's the default route for outbound connections.
One more thing that's bugging me: I still don't understand why I couldn't connect to the internet when I plugged in the Ethernet cable from server to router. Even if I was using DHCP to get a dynamically allocated IP, shouldn't it still have worked? I'm worried that I'm going to set up everything as it should be but the connection still won't work.
That's likely because you're trying to use the Mac as a router, and that takes specific configuration steps. It's easier to have ISP>firewall>LAN, and have the Mac OS X Server box and the rest of the stuff as peers on your LAN. If you really want to use the Mac as an IP router, look around for setting up static routes on Mac; there are postings around for that.
If your data is more valuable and your security preferences and requirements are higher, then you may want a firewall with a DMZ, and put your web-facing boxes over in the DMZ. If you're serving stuff to the web or a mail server or such, it's possible to get breached, and a breach means folks can potentially get further into your LAN. With a DMZ, they're somewhat more isolated from your LAN.

Just resolved Back to my Mac issue called Apple Suppport in the UK and they were really helpful if the error DNS server not responding the problem is with Apple server not your server ( I had tried to reboot by router, restart my laptop etc.

I was having problem with my Back to my Mac as message was saying DNS Server not responding . I tried to turn my WIFI off, then my router to no avail. Decided to call Apple Support line in the UK . I got a call back immediatly and great support. The advisor took over my screen and we check that my laptop was synchronising with I phots and it was. The adviser also told that when the message DNS server is not responding next to Back to my Mac is has to do with Apple Server not mine , router etc... Hope this save others some time! Rather than spending time truining on and off changing IP address etc...

Thanks for your thorough post. I too need to use BTMM on almost a daily basis for my job, and it has fallen short countlness times. I too have taken great pains to check all of the typical trouble shooting steps within iCloud and in the Apple keychain on each Mac etc, but after the latest rounds of system updates from Apple a few weeks ago to Mountain Lion, BTMM on one of my Macs is completely broken and unusable. I would concur that if you need remote access for "real" mission critical use, just bite the bullet and pay for a service like LogMeIn. You won't regret it and you will get real software support.

Clients lose only DNS server. HELP!

Hello,
I've encountered a problem these days with my dns server. My clients gets a 192.168.0.1 dns server, instead of the server dhcp/dns 192.168.74.3. I verified the dhcp/dns server and everything seems to be ok. This happens all random. When I disable/enable
the LAN or use the ipconfig /release /renew command the everything works fine for half an hour or so then it's changed back to that fake dns. Any advice?
Thanks!

Hi,
When the DNS server changes to 192.168.0.1, does ipconfig /all tell you that the IP address configuration currently in use is assigned by DHCP? If so, then what is the DHCP server that assigned this configuration?
For example below the DHCP server is 192.168.1.1:
Ethernet adapter vEthernet (External Network):
   Connection-specific DNS Suffix . :

If you can identify the DHCP server that is providing this DNS server to you, then you can shut it down. This might be a rogue DHCP server on the network, probably using itself as a DNS server.

Moving from Exchange 2007 to 2013 (leaving the DNS Server for it's own dedicated server)

Hello! I am quite new to Exchange and Server management in general. I will do my best to explain my situation.
I am looking to move my Exchange server off of our DNS server. When we installed them on the same server, we did not have the funds to buy 2 separate servers. I am told that it is best to separate the two. I have followed the Microsoft instructions for installing
the prerequisites for Exchange 2013 on a 2012 R2 server, and i am at the point where it wants me to configure AD LDS. As I have active directory running on the current server, I was a little hesitant to just install it without understanding what i am doing.
After the AD LDS is configured, I believe i can move forward with installing Exchange 2013 (all 3 roles will be hosted on the new server), export the mailboxes from 2007 server and import them into the new Exchange 2013 server. After 2013 is up and stable,
I plan on removing 2007 from the old server (DNS server).
What are my next steps after importing the mailboxes? Am i missing important details that I need to change or migrate?
My biggest fear is that nothing works after the installation and moving the mailboxes over. For that case, it makes sense to keep 2007 installed as a fallback for when my installation fails and all i have lost is just my time :)
Current Server:
Windows Server 2008 Standard (64 bit)
1. Roles: Active Directory, DNS, IIS
2. Software: Exchange 2007
New Server:
Windows 2012 R2 Server
1. Roles: ???
1. Software to install: Exchange 2013
Thank you for any help you can provide!

These are good resources, but i am still caught up with the active directory issue. Am I able to keep the old Domain/DNS/Active directory on it's current server and move Exchange 2007 off onto a new server (with Exchange 2013)?
In the first example, he is moving everything (domain controller, exchange, users, etc) onto a different server and decommissioning it.I've been told that it would be better practice to keep the domain and exchange on 2 different servers. Is this true?
I go to run commands like:
.\setup /PrepareAD /OrganizationName: orgname /IAcceptExchangeServerLicenseTerms
on the new exchange server, as a prerequisite and it doesnt recognize the command - even after following the steps before. Is this because the new server is not a domain controller? does it have to be? What are the best practices for setting up a server(s)
with exchange + domain controller?
Thanks for responding.

Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding [and I'm at my wit's end!]

I originally posted this question to the community section and was advised to post it here. Please bear with me as this will be a long post. I'm including the scenarios involving this reoccurring issue, the trouble shooting steps I've already
taken and the results of several diagnostic tools and logs.
I have a Sony VAIOS VPCEBB33FM lap top since 2011. I have had this issue on an off for a long time. I'm at my wit's end. Any new insights or suggestions would be greatly appreciated.
Scenario Details
1) Some times it's on and off through out the day, sometimes it won't work all day, and once in a while it will work fine for the entire day.
2) I've had this issue across several wireless services, Clear Network accessed with WiMax, Library Wi-fi, Comcast cable internet using wireless router and Wi-fi, and Comcast Xfinity Wi-Fi, to name a few examples.
3) Other devices in the household or library will work with no problems such as my smart phone or my roommates' laptops or desktop computers.
4) Once in a while, the built-in wireless adapter is not found and I have to reinstall the driver. Also the diagnostic tool has had to reset my adapter on an increasing basis.
5) I had my hard drive replaced in December 2014 and my system restored from the System Restore disks that came with it when I bought the laptop. Even though I've been online on an infrequent basis it worked just fine for a while. Now that
I've been online a bit more I'm having the same issues again.
Below are my attempts at trouble shooting so far but I still have not been able to consistently resolve my DNS issues
1) Restarting my adapter
2) Turning off my laptop and removing the power supply for 5-10 minutes before turning it back on.
3) Using the IP Config in Command Prompt
     ipconfig /flushdns
   ipconfig /registerdns
   ipconfig /release
     ipconfig /renew
4) Using the NetSh reset in Command Prompt and restarting my laptop
     netsh int ip reset c:\resetlog.txt
     netsh winsock reset
     ipconfig /flushdns
     [restart laptop]
5) Configuring the TCP/IP in several settings
    Select Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
    I have used the following settings:
       a) Obtain an DNS server address automatically
       b) OpenDNS
           208 67 222 222
           208 67 220 220
       c) Google DNS
           8 8 8 8
           8 8 4 4
6) Updating the driver for my Intel Centrino(R) Advanced-N 6250 AGN and Intel Centrino(R) WIMAX 6250 from the Intel website previous having my laptop wiped clean in 2014. It still did not resolve the issue. My laptop
manufacturer as not come up with an driver update for my adapter since 2010. I haven't tried to update the adapter driver from Intel's website since having my laptop repaired due to the fact that Intel strongly recommending using the manufacturer's updates
instead and frankly it didn't make much of a difference when I did it the first time.
7) The last one I've tried as of today is going into Services and changing the start up type to automatic for the following:
       Computer Browser [changed from manual to automatic]
       DHCP Client [already set to automatic]
       DNS Client [already set to automatic]
       Network Connections [already set to automatic]
       Network Location Awareness [changed from manual to automatic]
       Remote Procedure Call (RPC) [already set to automatic]
       Server [already set to automatic]
       TCP/IP Netbios helper [already set to automatic]
       Workstation [already set to automatic]
...and I'm still having DNS issues.
My only guessing are that my laptop came with a lemon adapter that needs to be replaced, some advanced setting(s) that I'm not aware off, or my firewall/anti-virus is interfering. I've used Symmantic Anti-virus and Firewall in the past and currently
Avast Anti-Virus with Microsoft Network Firewall. I've had DNS issues with both anti-virus/firewall set ups.
Below are the results from the diagnostics and tests that I've ran.

External DNS server not replicating records to secondary after migration from 2003 to 2012

Hi
I have a query relating to 2012 Server and DNS.
Last week we de-commissioned our primary external DNS server (Windows 2003 Server) and moved the role over to a new Windows 2012 server.
Since this point replication to our secondary server (3rd party hosted) does not seem to occur and our DNS records seem to have expired on the secondary server as we cannot look these up via nslookup.
I cannot see any failures in the event log of the server; I have checked our external firewall logs and nothing is being blocked inbound/ outbound as far as I can see. And the server’s local firewall has been disabled.
The server is a standalone server in a workgroup with a standard filebased primary zone, with no AD integration and recursion disabled.
When I created the zone I copied the .dns file from the old server and selected this in the interface during the creation of the zone on the new server. The new server has the same internal and external IP as the old server and the old server is off-line.
I have also manually increased the serial number of the zone and still no joy.
One thing that I have noticed is when I open the zones properties/Name Servers and click edit on the external nameserver I get the infamous "The server with this IP address is not authoritative for the required zone" error.
Any help Would be appreciated, thanks in advance

Nice to hear that you are close in finding the problem. So in short:
You have enabled Zone transfers in DNS management console for the applicable zone
You have verified that your DNS is listening to the correct interfaces
You have enabled firewall rules to accept TCP and UDP traffic to port 53
You have checked if "BIND secondaries" option is applicable to your case
You have initiated a zone transfer from the secondary server

How do I close an open DNS Server

I have received an email from my internet provider stating I have an open DNS Server and my network has been used to attack other networks (DOS) Denial of service. I can't figure out how to secure my network. or close the open DNS server.

You should at least update your Mac to 10.6.8 although I am not sure there are any particular security issues that would be there.
Of course running later OS is always better.. as the latest security updates are implemented in the most recent OS.. but I am not sure one follows the other as some weaknesses are introduced as well in later OS. Any security updates should certainly be installed.
The main point is what modem and what router do you have?
There are a number of these notices being sent to users with apple routers which are hard to believe can be involved. It is more likely the ISP equipment. But we cannot really help you with exact details of your network .. or any more precise details the ISP has given you.
Ring up and talk to their technical help dept. and ask for their help. Even if they won't help you fix apple router.. put the modem in router mode or buy a new modem with router mode and change the apple router to bridge.. then the issue is not caused by you and the ISP can remotely adjust their own box.

DNS Server Errors 4015 and 4010

Hi all,
we have upgraded a 2003 Domain to 2012 R2. All DCs now are 2012 R2. The Domain and Forest Level are 2008. Be checking the Eventlogs of the DNS Server we found that we have DNS Error 4010 and 4015 Events repeatedly.
4015:
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error.
4010:
The DNS server was unable to create a resource record for f55ab78a-df8d-4c2c-8420-52dc8b5604e2._msdcs.domain.local. in zone Domain.local. The Active Directory definition of this resource record is corrupt or contains an invalid DNS name. The event data contains
the error.
We found that the Errors are available on oll DCs. The errors occurs only after the DNS Server Service are restartet on the DCs.
We check the dcdiag /e /test:dns with all PASS
We check the netlogon Service are successfully update be a restart the _.msdcs records in the Zone if the record are not present
We check the _msdcs.Domain.local Zone, it is in the forest Root Partition and AD integrated. We move it to the root of the DNS like the KB817470 describe
We check the dns by the Best Practices Analyzer, wihtout a error
We check the AD replication by repadmin without error
Thanks for help

Hi,
Can you tell more information about the migration?
The roles that installed on windows server 2003 before migration. Is DNS role installed on it?
You can refer to this similar thread:

How do I use internet sharing from my MacBook Pro (static IP, only one DNS server) to my iPod Touch?

Hey,
   I'm connecting to the net using an Ethernet cable to my MacBook with the following network settings.
IP Address: 192.168.y.{0-250}
Subnet Mask: 255.255.255.0
Router: 192.168.y.x (where 'y' is the same number as in the IP address)
DNS Server: 192.168.99.3
Apologies if I'm being unclear; not sure how much information it's OK to share publicly.
   I then turn on Airport and Internet Sharing, and look for my wireless network with my 4th generation iPod Touch. However, the network appears erratically. I sometimes have to wait for a minute or two and keep refreshing before it appears on my iTouch. When I try to connect it just says 'Failed to connect to the network'.
   I've followed all the steps in this article with several variations to no avail.
http://lightyearsoftware.com/2010/06/how-to-set-up-internet-sharing-on-mac-os-x/
   Can anyone suggest a solution? Any help would be greatly appreciated. I've been banging my head against this for days.

On the advice of a friend I installed and ran a program on my MacBook called 'IPSecuritas'. This has stopped my wireless network from appearing and disappearing, but I still can't connect. Would really appreciate some help with this.

How do I create a backup DNS server?

Hi All,
I've got my production server (Xserve Intel) running 10.6 and it is our primary DNS server. I've gotta take it down to do some work on it, but by doing so, no one in the organization will be able to access the internet.
I'd like to set up my old Xserve (G5, running 10.5) as a backup DNS server that can handle the DNS requests whenever I need to take the main server down. Unfortunately, I'm kind of a DNS n00b.
What is the best way to go about this?
Thanks,
Chris

Oh, quite embarrassing. I complained about not understanding the author of the article when I was actually speaking to the author. How rude! Apologies, kind sir.
I've now got it set up correctly with your help, it seems. I've just got a few other questions regarding the Secondary DNS Server if you don't mind:
1) Do I set any forwarder IP Addresses on the secondary server? Should I put the same forwarders that I use on my primary, or should I put the IP address of my primary in there, or should I just leave it blank?
2) *Edit - Ignore question 2; found the answer in your guide*
3) When I look at the secondary zones, they don't seem to be populated with any data. . . Does this mean that the secondary server is completely reliant on the primary server to function correctly? In other words, *when I take my primary server offline, does the secondary server still work?*
Thanks,
Chris

New HP LaserJet Pro MFP M127fw network connection impacts DNS server of my ISP

Hi,
i am not well with english, so please sorry
I have deliverd new HP LaserJet Pro M127fw to my client who have 3 PC-s Win7 64bit, one 4 port switch, and one TP-link ISDN modem-router.
I have installed the printer over network and everything is done well. Printer is working in printing/scanning/fax/ and copy.
In few hurs local ISP has called and said that his DNS server is impacted by something from local LAN. After investigating, i have fount that printer is doing impact to DNS of ISP. When i remove LAN cable from printer, everything is fine with network
I have installed new frimware from HP.com. also I have change Admin pass. The new up to date software is installed.
Still have problem, and no solution. For now printer is working with USB connection, but that is not a option.
HP please help!

Hi @ITMračunari ,
I see that you are having issues with the printer connected by a Ethernet cable to the network, the printer is impacting the DNS of ISP. I would like to help.
Turn the IPv6 off on the printer to see if that will help.
Go to Setup, Network Setup, Network Services, IPv6 and turn it off.
This is a Consumer product and has been proving to work with a direct connection to a router.
I noticed in your post that you are also using a switch, which could possible cause other conflicts.
Hope this helps.
Have a nice day!
Thank You.

Need a suggestion for a DNS server (BIND etc...)

I am a student in college. I got a little job to help improve the internal DNS management in the college.
Right now they use BIND with nothing else. They edit the zone files by hand. Since the network is quite large, it's sometimes hard to maintain these files.
There are three possibilities:
1) use webmin.
2) use DLZ (still BIND, but uses a database backend)
3) use another DNS server software.
I would really appreciate your advice about:
1) lets assume webmin doesn't support a particular record of the DNS, and I update it manually via directly editing the files, will it interfere with webmin?
2) did you try DLZ? I don't know if it worth the work. Does it noticeably change the performance? Is there a decent GUI for editing the records when using a database?
3) I've heard many good things about PowerDNS. Is it really the best DNS server around? What GUI options does it have? Do you want to recommend another solution?
Thank you!

dnsmasq is hands down the easiest DNS (and DHCP!) solution if it works for your network setup. If you let it handle both DHCP and DNS it will dynamically add DHCP client host names to the DNS so you can look up local DHCP clients by DNS.
I am by no means a DNS expert, but dnsmasq just makes it all so easy.

Strange issues with domain controller/DNS server

Our domain controller/DNS server was working fine this morning. Then suddenly we stopped being able to access certain things on it. I could ping it, RDP into it, and access some files on it, but I couldn't run any applications hosted on it, accessing shared
network files was slow, and different people around the office were getting access denied errors to files and folders they had full control of in NTFS (and in shared permissions).
At first I noticed an NTP error so I registered w32tm and started the service and that got rid of the error but didn't fix anything.
Oddly, machines still had internet access.
We tried rebooting everything, restarting services, nothing has helped.
When I accessed the server directly through the console I could access everything, could connect to any machine in the office, nothing seemed to be wrong with it.
Any ideas?

Is there any recent changes in your network or firewall or antivirus? Is there any change/updates performed in the AD side? I would suggest find out changes being done at the AD or Network/FIrewall level. You can run various diagnostic test within your AD
environment to find the overall health of the AD infra.
