Many thanks

As I sad in my post, if you are managing a Windows DNS server, just open the DNS administrative tool and update the Root Hints there. If you are not managing DNS server, just forget about them.

Be very careful what where you get the numbers from. If you enter wrong addresses you could expose yourself to a man-in-the-middle attack.

Hi and thanks to both of you. I have noted a couple of addresses within root hints on server 2008 have changed when comparing ing to the latest available internic so I was looking for an automated way if updating them, I wasn't sure I could edit the current IP address for a root domain and just starting changing the IP address manually without it causing a problem because I note that from with dns mmc all you have is the domain name and IP address but from internic for each address there is additional information for each domain entry, if you go to the URL in my first post you will see what I mean- they show additional information which I can't see in dns mmc an so don't know if u simy start changing te IP address's it wouldn't cause a problem. I appreciate all the help but I'm still not sure ( please forgive me) on the actual step by step method of changing the root hints that ship with server 2008r2

Unfortunately with Microsoft DNS I can't see an easy option to update the root hints automatically.

With Internic there is indeed additional information but if you do it via the DNS MMC, the interface will automatically add all the necessary info.
If you take the first entry of Microsoft's "cache.dns" (which was created by using the DNS MMC).

.                        3600000  IN  NS    A.ROOT-SERVERS.NET.
A.ROOT-SERVERS.NET.      3600000      A     198.41.0.4

Select allOpen in new window

and compare it to "named.root" from Internic

.                        3600000  IN  NS    A.ROOT-SERVERS.NET.
A.ROOT-SERVERS.NET.      3600000      A     198.41.0.4
A.ROOT-SERVERS.NET.      3600000      AAAA  2001:503:BA3E::2:30

Select allOpen in new window

Then the only difference is that Internic adds (in the last row) also the IPv6 IP-address of the root server. In this case 2001:503:BA3E::2:30
As the DNS server is an IPv4 DNS server this information is not applicable.
All other information is the same.

.          Root node
3600000      Time to live (this field is for historical reasons and not used by the DNS server)
IN          Stands for Internet (DNS class field)
NS          Name server record (Resource record)
A          IPv4 host record (Resource record)
AAAA   IPv6 host record (Resource record)
198.41.0.4      IPv4-address
2001:503:BA3E::2:30      IPv6-address

Select allOpen in new window

I can confirm that it's possible to edit the IP-addresses manually via the DNS MMC.
My recommended way of doing this is by opening the named.root with a text editor and then copy (control-c) the IP-address in the text editor and paste (control-v) the IP-address within the DNS MMC while verifying you select the correct root-server name. If you would verify each entry twice than everything should be ok.
At the end of the change you might restart the DNS Server service to be sure everything is loaded correctly.

Thank you.
