    Scanning SMB to Win 7

    I am starting to see this a lot lately. Customer's are using a win 7 box as a "file server" and it also has a scan folder for scanning. If mutable people are using the "server", scans will fail.
    If you reboot the computer, scans start going through again. So far I have seen this problem with our Konica and Muratec boxes. Has anyone else see this?

      There is a limit to Windows client OS itself for concurrent TCP/IP connections. A 20 connection limit is specified in the Windows 7 EULA for other devices to connect to access file services, print services, IIS, ICS ect.

      If you create a share by default it has this set for 20 connections which is the max.

      If this limit is reached you would see error 4226 logged in event viewer.

      You could run a netstat -o command to find out what is hammering your open ports.

      Although against the license agreement with Microsoft there are registry edits if you search that may disable limits. Not sure its a good idea though. This is one reason why Server OS are used.
