A computer that is running Windows Vista or Windows Server 2008 may crash intermittently. Additionally, you may receive the following Stop error message:
This problem typically occurs when multiple third-party network drivers are installed on the computer. For example, this problem may occur when the following drivers are installed:
This issue occurs because the Tcpip.sys driver occupies most of the space in the kernel mode stack. This leaves less space in the networking stack for the regular operations of the operating system. Therefore, the system may crash intermittently.
Note After you apply the hotfix, the way that the Tcpip.sys driver uses the networking kernel mode stack is optimized. Therefore, there will be more space in the networking kernel mode stack and this problem is less likely to occur.
