XP workstations after a period of time are no longer able to connect to Windows 7 shares until the Win 7 machine is rebooted.
Running time 12-24 hours before problem the arises.
Only Windows XP workstations are affected. Networking or permission errors are displayed on the Win XP machines as they are unable to reference the shares on the Windows 7 PC. However we can still ping IP of the Win7 PC and connect to MySQL running on the Win7 PC.
We are running a Windows 7 64 bit PC as a file sharing server with 4 GB memory. Network has 4 Windows 7 workstations and 3 Windows XP ones.
3 folders off the root directory on the Windows 7 PC have been shared by Right clicking on folder, selecting Share with, then Specific people.
Set so 'Everyone" has Read/Write access. So security is set to Full Control for Everyone on the shared folders.
When a Windows XP system fails to connect to a share, all other Windows XP systems follow suit. Windows 7 Workstations are not affected.
Found errors on the Windows 7 (file server) system logs that occur at the same time as the problem and is repeated many times:
Event ID: 2017
Task Category: None
Description: The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.
I have found some references that relate to this error for Vista 64 bit suggesting to disable SMB2 in Registry and/or change MaxNonPagedMemoryUsagein registry from 1 to 3.
I am just hoping to find out something more definitive.
