This is a theoretical situation you have a completely failed DNS  structure for windows , lets just say there is no way to stand up any kind of DNS resolution that is windows based . I need a unix type application in BSD or Centos or something you tell me ? that will run DNS it must be easy enough for a windows guy like me to set up easily .
What is any problems will the windows server using UNIX based dns encounter? I need the quickest solution not the one with bells and whistles ,

BIND is the most popular and well-supported DNS server for Unix/Linux.
yum install bind bind-utils

Open in new window


What is any problems will the windows server using UNIX based dns encounter?
There won't be any problems.  If you have AD setup however, you will want to create records which Windows clients will use for things like discovering domain controllers --
Ok, now the actual part that makes things work. In order for a workstation to find out which server is the DC, four SRV records are required to complete the deal for each DC. This example is for one domain controller, so the weight and priority fields are set to zero (0). Also, you should be able to see that the LDAP service uses port 389, and the Kerberos service uses port 88.

If you have an Address Record (A) that identifies your server name like this:

dc1.example.com. A 111.222.333.444

Then your SRV records for this DC would be as follows

_ldap._tcp.example.com. SRV 0 0 389 dc1.example.com.
_kerberos._tcp.example.com. SRV 0 0 88 dc1.example.com.
_ldap._tcp.dc._msdcs.example.com. SRV 0 0 389 dc1.example.com.
_kerberos._tcp.dc._msdcs.example.com. SRV 0 0 88 dc1.example.com.

BIND can be very complex/custom, or very simple and "straight-forward".

Since this is a hypothetical situation, I'm not going to go into details of best practices for named.conf and things of that sort.  If however you decide to install BIND and do need that sort of info, I (and other experts) can give more focused advice.

so theoretically all my windows clients are pointed to a DEAD DNS server at 10.1.1.20 , if i where to bring up a centos? or ? install ( is it all free?) and give it that ip of the dead windows dns server i could use this to service 850 windows clients ?

the YUM set up , your run that from any centos box that has internet access and it will down load it right ?

Yes and yes.

Correct.
is it dyamnic ?
It can do be configured to allow dynamic updates, DNSSEC, split DNS, etc etc -- pretty much anything you need from a DNS server.
