0x8007046A When Copying a Large File

October 31, 2012 Leave a comment

Warning: This post deals with editing the registry. If you don’t know what that is stop right here & ask someone else to help you. Using the registry editor incorrectly can cause serious problems that may require you to reinstall Windows. Use the registry editor at your own risk.

When copying a large file from Windows Server 2003 to Windows Server 2008 R2 you may receive an error that says, “Error 0x8007046A: Not enough server storage is available to process this command.”

If you try to copy the same file to a USB hard drive on the Windows Server 2003 box you get a similar error that says, “Cannot copy filename: Insufficient system resources exist to complete the requested service.”

To resolve this create the following registery entry on the Windows Server 2003 box & reboot the server.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
“IRPStackSize”=dword:00000015

If you still receive the error you can increase the value by 3, reboot & try again. The maximum size is 50.
