Running Windows 7 pro Hundreds of Event 2017 errors

Running Windows 7 pro on an HP z440 computer.  It is a member of a Windows 7 peer-to-peer network.

The event system shows this machine having over 1,000 event 2017 errors.  The error message is
The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations

I searched the web for an answer.  These answers told me I was to change the registry.  They told me to change registry key:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

Well, this machine does not have that key in the registry.  This machine has the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\
and two sub keys:


What steps do I perform to stop event 2017 errors?  Please provide detailed answers.  Useful links are always welcome.

Thank you for your help.

If you do not have subkeys in the registry you can always create them.

How many devices are communicating with this Windows 7 computer?

Hello 65td:

Thank you very much for the links.   The social.technet is the link I found.  The Spiceworks link is very helpful.  
I did not know there was a limit of 20 connections to a computer.

Hello Shaun :  This computer communicates with 5 other Windows 7 computers and a network printer.

Follow up question to anyone:
I know VERY little about SMB.  My question:  Let's assume computer 100 is a member of a peer-to-peer network .
Let's further assume there are 20 computers in this peer-to-peer network.  Each computer has an administrator account and a regular account called Bob.  Bob account is on all computers and has the same password on all computers.

So, assume I walk over to computer 100 and turn it on and all other computers are turned off.  
I log into computer 100 as Bob..  I don't do anything else, just log in.
Now I  go to computer 200 which is a member of the peer-to-peer network . I turn on this computer and log in as Bob.
I assume 1 SMB connection is being used on each computer?  I assume the computers have sent signals over the network asking “Who is on this network?”

In other words, when is a SMB connection created in this peer-to-peer network ?
How will I know when the limit of 20 is reached?

May be you know of a link which would answer my questions and would provide more information about SMB?
Ignore the story with the SMB, and it's just confusing if you are not technical. Imagine the PC is a barrel water and you can use maximum 20 staws for drinking at a time. Is your issue solved or still pending?

I rarely ever look at the registry.  I discovered I do have the keys.
I changed them using the link 65td  provided.

The errors seemed to have stopped.

Thank you all for your help.
