Hi,

That's my question, could I change the DNS configuration with the DNS service stopped?. We need to replace and old DNS server and we need to do some changes in the new DNS server before the replacement.

Thank you.

yes you can - but the clients will be lost without a namespace for a while.

As above, you should however be able to make many configuration changes without stopping the service. What is it you plan on doing?

Are you sure?.

I get the error attached when I open the DNS console.

Yes I am sure you can make many of the configuration changes to the DNS server without taking it offline.

Like I asked, what is it you are changing?

That message suggest you are trying to connect to a server that is not either not a dns server, that the service is stopped or the server is offline.

Once the new server was working as a secondary server for many zones and at this moment it has a lot of old and wrong entries in its database. If I start the DNS service I guess it could give wrong resolution to the clients. It also has wrong A records which were manually added.

On the other hand, How could I make any change with the service stopped?, may be editing the dns file?, is impossible to make changes with some GUI interface?.

Thank you.

Modifying your DHCP scope so the clients do not look at the DNS server in question, that would solve the issue of clients looking at it.

How is your current DNS server configured btw?

Most Windows DNS service configurations consist of AD Intergrated DNS, where the zones would be replicated from one server to another, it's odd that you have taken a server offline so would need to understand the configuration a little more.

The DHCP scope was modified a long time ago, that's not the problem, I'm afraid of any other server that was poitning to the wrong DNS server.

The DNS is integrated with AD, so if I start the DNS service, will it be any problem?, do you think that the replication will be right?, I'm afraid of some conflict.

It should update from your current DNS server in that case the zones are stored in AD so it should pull the info from that. There is a possability that you may encounter some minor issues but nothing you won't be able to handle.

Anyway, how can I make changes the likes of adding a A record to a primary zone with the DNS service stopped?.

Take a look at your zones files on the server located @ C:\WINDOWS\system32\dns

You can open them with notepad.

To my knowledge you can either use the GUI to modify AD intergrated Zones (which you have access to) or you can use the Dnscmd tool (Which I am not overly familiar with as I use the GUI)

Or if the zones are standard primary/secondary you can modify the zone files directly by editing the zone files located at C:\WINDOWS\system32\dns

Those are the only way I know/use there might be a thirday party tool you can use but as you already have access to the AD Integrated zones via the GUI I don't see the need.
