Domain DNS problem

[xeryph]

Hello!

We have 25 servers with directadmin. On two of them we install DNS and use multi-domain in directadmin to connect from all servers to them. It works very well, but in last time we have a lot of work with some kind of problem.

First of all some domains are in DNS on one day, but on a second one they disappear and dont work. We have to add them to dns once again. Domains are in directadmin user panel.

Do you have that problems? How can I fix it?

Now we have only that work in support. Thanks.

To be clear ...

1) are you saying that you have 25 servers with DirectAdmin control panel licenses installed and in production?

2) of your 25 servers, you have only configured 2 of them with multi-server setup?

to be clear on point 2), what are the other remaining 23 servers setup to do? multi-server also? if not that could be the problem...

Dear ranz,

I have 25 server where are my customers. On every server I have multi domain service open to connect to two main dns servers. Two servers are only dns servers with directadmin installed on them.

Thanks.

have you checked this:
http://help.directadmin.com/item.php?id=97

otherwise you will need to check how the servers are connecting to each other (i.e no firewall, via http or via https, public IP or on a LAN/Private IP etc etc)
