Does anybody know the max number of concurrent smb connections that can be made to a Windows 7 Ultimate machine at one time for file and printer sharing? I know the limit is 10 in XP Pro and 5 in XP Home edition, just we have more than 10 users and don't want to upgrade to a server OS at present.  I have had a look around on the net and most people say it is 20.

I believe it is 20 connections on windows 7.  You can verify this as follows.

Go to Start > Run and type winver then click on Microsoft Software License Terms and scroll down to Section 3 f. - Device Connections
LVL 20

You can also download the EULA as a PDF from here:

It's section 3 e. - Device Connections in that document, and it states it allows up to 20 connections.

So 20 pc's can connect to file shares concurrently on Windows 7 as oppose to Widnows XP pro's limit of 10.

As long as no other PCs are connecting to printer shares. You get 20 connections total for both file and printer sharing.
