He mentions in that article turning off NBT/TCP and then says that the SMB
connection is over the CIFS port (TCP 445).
In his article he turned off NetBT/TCP so that would make sense. Be aware
that downlevel clients will make this different in that they will use TCP
137-139. Also, the number of users is not the same as the amount of
computers in the domain that would use this service since they won't all be
using their own machine (in some environments anyway).
You should see at least one SMB connection for every computer account that
logs in at a minimum (each computer account is just an object as a user is)
and possibly more as Tony mentions. In your case 20,000 SMB's is not
outside the realm of possibility but the number would be expected to be much
higher.
What would be more of a concern is the number of SAM/R pipes on a Win2K
domain controller. ;)
What made you curious about this?

Subject: Re: [ActiveDir] SMB Connections to a DC; How many is normal?
The SMB interactions between clients and DCs are covered in this article by
Darren Mar-Elia.

It doesn't mention how many to expect, but I think this will vary depending
on number of GPOs, Dfs, etc. You would also expect a higher number of
connections during the morning logon peak.

I know this question is relative but lets say I have a 20K User Domain with
17 DC's, the DC's have a Gig of RAM and Dual Procs. What would you say is
the average number of SMB connections that should be connected to the box?
I know that as long as performance isn't slowing I am fine, but I am just
looking for what people think and why...
Thanks,
Todd
