If the number of 80 SMB connections is the threshold, is that a per second number? Is that total? Is that per second over five minutes?
I would expect the total number of SMB connections to remain much higher than 80 so I'm interested in how they would arrive at that threshold and what it means.

Thanks all... I will review the article... I just installed Netpro Directory Analyzer, and their default setting is like 10 or 20 SMB connections. I had something like 80. I reviewed the connections and saw some connections for like 18 days. Today I just got notified that the page file on the PDC emulator spiked to 81%, we have a Gig of RAM in the box. So I am trying to normalize the DC.

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? -----Original Message----- From: Tony Murray [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 23, 2003 4:15 AM To: [EMAIL PROTECTED] 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. http://www.winnetmag.com/Articles/ArticleID/37928/pg/1/1.html 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.

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...
