//example.com/inetpub2 /nolmcs02/inetpub smbfs credentials=/root/nolmcs2-auth.txt,domain=NATIONAL,uid=noladmin,gid=noladmin,directio,hard 0 0
where /root/nolmcs2-auth.txt (or whatever you name it) is a file containing the username and password to use:
[root@nolappsdc01 ~]# cat /root/nolmcs2-auth.txt
username=
password=
You can mount this manually to test using:
mount -t smbfs //example.com/inetpub2 /nolmcs02/inetpub2 -o credentials=/root/nolmcs2-auth.txt,domain=NATIONAL,uid=noladmin,gid=noladmin,directio,hard
The credentials file is used so it will work on restart automatically. Instead of credentials=, you can use username=, etc. temporarily.
