Queries going to OLD DNS 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.
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.
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).

> non-TCP/IP related path [...]
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.
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.
1.None of *.dat; tcpip database files updated
where is new DNS IP's updated?any idea.
===================
TCPIP> SHOW CONFIGURATION NAME_SERVICE
BIND Resolver Configuration
Transport: UDP
Domain: ASPAC.CITICORP.COM
Retry: 4
Timeout: 4
Servers:
Path: No values defined
====================
New DNS ip's are showing here..
Is it required to remove the oldDNS entry completetly or if i changed the sequece of DNS ip's then it will check 1st IP in sequence and if this is not rechable then server will look for 2nd IP ?

Re: Queries going to OLD DNS server.
IIRC, the resolver uses the servers in the order given.
You should remove the old servers' IPs by using
$ TCPIP SET CONFIGURATION NAME_SERVICE /NOSERVER=(old_ip[,old_ip...])
and
$ TCPIP SET NAME_SERVICE /SYSTEM /NOSERVER=(old_ip[,old_ip...])
HTH,
Martin

Re: Queries going to OLD DNS server.
I changed the OLD DNS to NEW DNS in VMS successfully.Now all queries going to NEW DNS server.
Can we accomplish this task without restarting TCPIP startup?
