Error code 000000C5

Error code


As per M961799, this may be recorded when a user accesses shared files on the server by using a server message block (SMB) connection. The problem occurs because the Netbt.sys (NetBIOS) network driver incorrectly handles a buffer when a malformed packet is received from the network. A hotfix is available for Windows Server 2003 SP2.

M967208 describes a situation when a 32-bit driver that has a name with more than nine characters is incompatible with a 64-bit OS.

Microsoft suggests that this error is in almost all cases caused by faulty drivers. M244617 provides instructions in using the Driver Verifier.

The recommended troubleshooting approach would be to identify the driver and obtain and if possible obtain an updated driver. M302971 presents a condition where newer hardware used with an older driver may cause this problem.
