SYMPTOMS
One of the following bug check errors occur in Tcpip.sys, and your Windows Server 2003-based computer stops unexpectedly:
 * 0x19
 * 0xC2
 * 0xC5



CAUSE
This problem occurs because the TCP/IP stack tries to free a buffer that it did not allocate. When the TCP/IP stack tries to free a buffer that it did not allocate, the pool header becomes corrupted and the computer stops unexpectedly.
