CNAME ping through secondary IP Address

-

hi all,

i have 1 web server hostname "chn-vm-001" ip address of 10.200.2.10. have added cname "kb" this server , have 1 more file share server ip of 10.200.2.54. i migrated share 10.200.2.54 to 10.200.2.10 , i shutdown existing 10.200.2.54 server, added 10.200.2.54 secondary ip in 10.200.2.10 server. now, when ping "kb" shows 10.200.2.54. need 10.200.2.54 windows share \\10.200.2.54 , remaining services should work through 10.200.2.10 ip address.what should do?

it appears round robin kicking in. better tool use nslookup, not ping.

c:\>nslookup
kb

in response, show cname , ip. if hit arrow up, , run again repeatedly, should show rotating , forth between 2 ips. that's how round robin works.

if need 1 ip 1 set of users, , other set of users, have create separate names each ip server.

one suggestion:
disable dynamic registration on server. manually create 2 records server, 1 each ip, may have register additional spn other name, depending on how application works.

assuming not dc, can try:

domain.local
servername        a         10.200.2.10
servername-b     a         10.200.2.54
kb    alias     servername.domain.local
kb2  alias     servername-b.domain.local

but can challenging. anytime see machine multiple ips not teamed, it's challenge. , hope not domain controller, multiple ips/nics cause problems ad.

any reason can't use 1 ip?

-

late edit: 2 ips on machine cause netbios browse issues.
