we are using our router as DCHP server for all our branches. Recently some other company merged with us.
we have having dns issues as the users are not able to resolve the dns ,unless they add fully qualified domain name.
someone suggested to add option 119 in the dhcp pool.
current config looks like this.
ip dhcp pool USERS
network 10.226.129.0 255.255.255.0
dns-server 172.28.224.102 172.28.224.103
Other company domain name is xyz.net.
Please suggest the right solution. Also if i need to add it as option 119, should i use HEX value?
Not sure how to convert abc.net to HEX value.
Can you elaborate on what issues your facing regards dns resolution, what users are having the issues - all users of specific users/sites etc...?
Are you using NAT?
Do you have internal and external DNS servers
What is the outcome of a nbtstat -a xxx from a user?
