Here’s the syntax for that command:
drainstop [{Cluster[:Host] | all {local | global}}]
Disables all new traffic handling on the specified hosts. While draining, hosts
continue to service opened connections and stop their cluster operations when
there are no more active connections. Draining mode can be terminated by
explicitly stopping cluster mode with the stop command or by restarting new
traffic handling with the start command. The optional parameters allow the
command to address a specific cluster, a specific cluster on a specific host,
all clusters on the local computer, or all global computers that are part of
the cluster.
You may need to be more specific as far as what you are stopping but the above
command does – or should – do what is done through ISA. Or, since ISA actually
manages NLB, ISA may be restarting it after the draining finishes and NLB
actually stops on that node. I’m not sure what to do in that case. Jim?

I executed:
“wlbs drainstop”
and
“nlb drainstop”
Both did the same thing I mentioned before.
What I’m trying to accomplish is the same you do from the ISA console going to
monitoring/services right click over the NLB service and select “drain and
stop”, but from the command prompt or using a script.

Yes I tried both options, but look like the NLB drain, stopped and started
automatically.
ISA is showing that on the alerts tab, but I didn’t find a way to emulate the
drain you can do from the ISA console.

NLB has both an ‘nlb drainstop’ and ‘nlb drain’ command. Full syntax is listed
in online Help.

Doesn't nlb.exe have a drain parameter? NLB isn't my area of expertise, but I
thought you could "drain" from the command line somehow... I bet Jim knows ;)

But the thing is, I’m looking to specifically do a drain of the
service, no a stop. Is there any parameter on the net stop to do a drain, or is
there any other command to run a drain?

You'd have to do something like "net stop" in a script that uses
"RunAs" to escalate privileges. You could obfuscate the password in an encoded
vscript, but they could get to it if they wanted to badly enough.
But, you could tell them not to do that and then audit for logon events
for the account you created to do that-- at least you could know if it was
being abused.

Dears, I need to give some IT guys the ability to drain the NLB
service, but I assume the only person that can do that in ISA2004 or ISA2006 is
an administrator of the array or enterprise.
Since I don’t want to make those guys administrators of any
array, I’m wondering if there is a way to drain the service using a script.
Does anybody know a way to do it?
Thanks
