Here’s a little trick I learned a couple of years ago that managed to pop up again today.

The problem with Microsoft Windows XP/Vista/7 is that you have a limit on how many concurrent connections can be made to the device. Windows XP usually has 10 and Vista/7 has 15.

If you have a small network and happen to have more devices connecting to it, you’ll have to install an operating system that supports more concurrent connections. You could go the *nix route or install one of the server flavours of Microsoft Windows

Or, you can do this:

  1. Click START
  2. Click RUN
  3. Type in: regedit
  4. Click on OK/RUN
  5. Locate and then click to select the following Registry Subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
  6. In the Edit Menu, click NEW and click DWORD. (If exists, skip to step 8 )
  7. Type MaxMpxCT and press ENTER
  8. Right-Click MaxMpxCt and click Modify
  9. In the Value data box, choose DECIMAL ***
  10. Click OK and close the Registry
*** Note: You can set the number of concurrent SMB commands to a value that is between 10 and 255. The default value is 10 on MS Windows XP
Hope this helps >;]
