I have a Windows 7 Enterprise and Windows XP professional on domain.

Windows 7 has a share folder which windows XP access it but for some reason during the day I cant access the share but if I reboot the Windows 7 it start working fine again.

These are the things I have tried.

  • Both PC are in same domain
  • I have both NTFS permission and Share Permission on that folder
  • Share folder has everyone full access
  • Both PC HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous is set to 0
  • NetBIOS is enable on both PC (On network Card)
  • Logged in user has full admin rights on both PC
  • No limit is set for number of access to share
  • Both PC has different Name
  • Advance Sharing setting is turn of for all
  • print and file sharing is enable on network card
  • Firewall is turned off on both PC

If you check the windows 7 machine you should see event ID 2017

2017 = The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.

1. Do you have any third party antivirus or security program installed on your computer?

2. When does this error message occur?

This issue occurs due to the antivirus software present on your computer and also the less system cache.

As a test you may consider disabling security software on your Windows 7 machine and check for the issue.

Turn windows firewall on or off

Disable antivirus software

http://windows.microsoft.com/en-US/windows7/Disable-antivirus-software

Note :Enable all security software after the test.

If the issue gets resolved then I suggest you to follow these below steps.

a. Click Start, Run.

b. Type "regedit"

c. Set the following registry key to ‘1′:

Navigate to:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

d. And set the following registry key to ‘3′:

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

After making these changes, restart your machine.

Change following registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\siz‌​e 

was on 1 and had to be changed to 3.

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

 change to 3
