First you need to make sure your ISP is actually sending the name server
information in its DHCP replies (it should).
DHCP response? If not, then you may have to add a "require
domain-name-server" option to the dhcp options list.

That's the problem. I'm NOT getting the name server list from the provider,

You really do not know this. All you know is that your resolv.conf file
is not being modified. As root, do the following:
1. In the Yast sysconfig editor, Network/DHCP/DHCP client, check the
variable DHCLIENT_BIN to see if you are using dhcpcd or dhclient. Unless
something has changed since 9.3, there are no other choices in SuSE. The
default is dhcpcd, but dhclient is much easier to use if you are
configuring a single interface with DHCP.
2. Find out if it is actually running:
ps aux| grep dhc
3. If it is dhcpcd, then run this:
grep DNS /var/lib/dhcpcd/*
With this client, if you are receiving name server information from your
service provider, you will see a line similar to this:
/var/lib/dhcpcd/dhcpcd-eth1.info:DNS=204.83.142.2,204.83.142.4
If it is dhclient, run this instead:
grep name-server /var/lib/dhcp/*
With this client, you should see several lines looking similar to this
(dhclient has a habit of keeping a few old dhcp leases in its files):
option domain-name-servers 204.83.142.2,204.83.142.4;
4. If you see the appropriate line, then you are receiving the name
server information from the provider. In this case, since your config
variables are properly set to have the system modify resolv.conf,
something else is preventing that file from being modified properly.
IMO, that something can only be Networkmanager. If this is the case,
then dump Networkmanager (unless you have an absolute compelling reason
to keep it running), and let the system init scripts perform the task
for you. They do work, I assure you.
If you do not see the appropriate line, then you are not receiving
the information at all, and this becomes an issue of properly
configuring your dhcp client program. I doubt if this will be the case,
as both dhcpcd and dhclient, as they are installed out of the box, will
request name server information in a dhcp request.
5. If all else fails, take the name server information you got in step 3
(or call your service provider to get it) and modify resolv.conf
yourself. This is not the ideal situation, but it will at least give you
functioning name servers while you look for the problem elsewhere.
