Error message when you use applications that are based on legacy Transport Driver Interface (TDI) filter drivers on a computer that is running Windows 7 Beta or Windows Server 2008 R2: "STOP 0x000000D1

When you use applications that are based on legacy Transport Driver Interface (TDI) filter drivers, such as some antivirus programs, on a computer that is running Windows 7 Beta (Build 7000) or Windows Server 2008 R2 (Build 7000), the computer may crash during Server Message Block (SMB) connections when you are accessing network shares. The crash typically results in an error message that contains the following: Note You can use the winver.exe command to check the system build information.

This problem occurs because of an incorrect behavior in a system component that occurs when Server Message Block (SMB) connections go over Transport Driver Interface (TDI).

This problem is fixed in the RTM version of Windows 7.
