Problem with ping after server becomes local master browser

[Baskar Duraikannu]

We are using winbind to do AD Authentication so that users can login to Cent
OS using Windows AD domain credentials.

We have turned on winbind, smbd and nmbd daemons. nmbd goes through the
election process and becomes local master browser. After it becomes local
master browser, the server becomes not reachable (cannot ping using the IP;
cannot ssh into it).  Only way bring the server back is to reboot the server
using iLo.

Can someone help figure out the issue?

Here is our config looks like
[global]
        workgroup = XXX
        realm = XXX.XX.COM
        server string = Linux Server
        security = ADS
        log level = 3
        log file = /var/log/samba/%m
        max log size = 50
        default service = FILE:/var/log/krb5libs.log
        idmap uid = 600-20000
        idmap gid = 600-20000
        template shell = /bin/bash
        winbind separator = +
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes

[libdefaults]
        available = No

[realms]
        available = No

[domain_realm]
        available = No

[share]
        path = /share
        read only = No
        create mask = 0777
        guest ok = Yes

[tmp]
        path = /tmp
        read only = No
        create mask = 0777
        guest ok = Yes
        browseable = No
