Queries going to OLD DNS server.

Existing DNS resolver server going to Decommision and team provided the alternate DNS resolver server .

I've reconfigured/added NEW DNS resolver server(IP) into our VMS machines as below,
@tcpip$config.com;
1 - Domain
2 - Interfaces
3 - Routing
4 - BIND Resolver
5 - Time Zone

A - Configure options 1 - 5
[E] - Exit menu

Enter configuration option: 4
* Do you want to reconfigure BIND [NO]: YES
Enter your BIND server name:

Question:
N/w team is saying still your many VMS servers queries coming/going thru OLD DNS server instead should go NEW DNS server.

If i see into tcpip configuration i can see new DNS servers entries are there,
Can you help how can i trace this,
Please let me know if you need to more info.

Re: Queries going to OLD DNS server.

Did you check with TCPIP SHOW NAME, if the new servers are set?

May be TCPIP$CONFIG only updates the permanent configuration.

To set/view permanent:
$ TCPIP SET CONF NAME /server ...
$ TCPIP SHOW CONF NAME

To set/view volatile:
$ TCPIP SET NAME /system /server ...
$ TCPIP SHOW NAME

Re: Queries going to OLD DNS server.

Shiva,

Was the relevant part(s) of TCP Services restarted after the change in settings?

Note that this must be done through a non-TCP/IP related path (e.g., one cannot be logged in through telnet to do this; the connection must be either direct, or through DECnet --- and not DECnet over IP).

Well, yeah, if you're killing the whole
thing. I use this:

ALP $ type BIND_RESTART.COM
$ @ sys$manager:tcpip$bind_shutdown.com
$ @ sys$manager:tcpip$bind_startup.com
ALP $

I would not expect the world to end if you
whack the BIND server over an IP connection.

Re: Queries going to OLD DNS server.

There is weekly reboot so system already rebooted twice.
If we execute Bind resolver option and changed DNS server then which database file should update in our server, any idea...

Fyi - tcpip$host.dat file was not updated after this activity.
Is there any cmd to verify the default/primary DNS server.

Re: Queries going to OLD DNS server.

The information seems to be stored in SYS$SYSTEM:TCPIP$CONFIGURATION.DAT.

To check use TCPIP SHO CONF NAME
