Symptoms

This issue may occur when you perform reading or transferring files on a Server Message Block (SMB) server that is running Windows Server 2012. Additionally, the Stop error message resembles the following:


STOP: 0x000000C2 (0x00000007, parameter2, parameter3, parameter4)


Notes

  • This Stop error indicates a BAD_POOL_CALLER issue.

  • The parameters after "0x00000007" in this Stop error message vary.

  • Not all "0x000000C2" Stop errors are caused by this issue.

Cause

This issue occurs because of a problem in the SMB file system driver when SMB 2.0 uses Fast I/O request for the read operations.

Resolution

To resolve this issue, we have released a hotfix for Windows Server 2012. Even though this issue has only been observed in Windows Server 2012, the hotfix also applies to Windows 8.

Windows 8 and Windows Server 2012 file information and notes

Important Windows 8 hotfixes and Windows Server 2012 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems.
