Registering Multiple NetBIOS Names

[Hari Potta]

Hi everyone,

I have a WindowsNT Domain with Win2K servers.I have a
requirement for reducing downtime for my applications. I
have multiple 5 to 6 Win2K servers and I need to redirect
the UNC requests for multiple servers to the one Win2K
server machine in the NT Domain. Is it possible to do
this at all ? Any Ideas are greatly appreciated.

Thanks in Advance,
Hari Potta

Depending on your applications needs, you might want to try and Windows 2000
DFS Share. Another option might be Windows 2000 NLB (Network Load
Balancing). It really depends on the bigger picture needs.

Thank you Brian, for your ideas. But let me explain what
I am looking for:

I have two SQL servers names S1 and S2. I also have two
hundred users who depend on these servers for UNC access
and SQL access.These servers do run lot of scripts that
load data from each other in addition to letting the
client machines query and update the data. S1 normally
servers 100 users and S2 serves other 100 users. ( There
is lot of configuration goes into these client machines
for this requirement.) So If one of these servers
crashes, It is taking us lot of time to rebuild the
server, restore the data from tapes and Half of the
Production is Lost during this time.

During this time of a server being rebuilt,I wanted to
explore the possibilities of redirecting the users to the
OTHER server that is running. For instance, If S1 is
down, I can create another IP address on the S2 server
and create a static WINS entry pointing the S1 name to
this new IP address. I was able to PING by name BUT I am
failing to UNC by Name(\\S1\c$). I have tried to use a
Registry entry at
HKEY_Local_Machine\System\CurrentControlSet\Services\Lanma
nServer\Parameters called OptionalNames = S1 and it did
not help.

If you are truly using the SQL servers for SQL then you will be using
TCP/1433. Most of the time, assuming this is the case you can use NLB to
load balance the systems. This will create a virtual cluster of the machines
and you can load balance the tcp traffic.

But... if you are using SMB i.e. the unc path is to load balance files (word
docs etc) this then a dfs share should work well. Eitherway, this will allow
you to point all your clients to 1 name or 1 IP address. That way, you can
add and remove backend servers as needed and build from there.
