“0x000000C2″ Stop error occurs when you use IPsec on a computer that is running Windows Server 2008, Windows Vista, Windows Server 2008 R2 or Windows 7 in a network that uses IPsec NAT-T security
Consider the following scenario:
- You join a computer to a network. The computer is running one of the following operating systems:
- Windows Vista
- Windows Server 2008
- Windows 7
- Windows Server 2008 R2
- The network is configured to use Internet Protocol security (IPsec) network address translation traversal (NAT-T) security.
- You use IPsec to communicate with another computer in the network.
In this scenario, you randomly receive a Stop error message that resembles the following, and then the computer restarts:
STOP 0x000000C2 (parameter1, parameter2, parameter3, parameter4)
- This Stop error describes a BAD_POOL_CALLER issue.
- The four parameters in this error message vary, depending on the configuration of the computer.
