Hi
The following maybe of help
SYMPTOMS
When you use Performance Monitor to view TCP/IP performance counters, the
counters may not appear.
The Event log may contain an event that is similar to the following:
Event Type: Error
Event Source: Perflib
Event Category: None
Event ID: 1010
Date: 2/28/2003
Time: 3:44:25 PM
User: N/A
Computer: Computer_Name
Description: The Collect Procedure for the "Tcpip" service in DLL
"C:\WINNT\system32\Perfctrs.dll" generated an exception or returned an
invalid status. Performance data returned by counter DLL will be not be
returned in Perf Data Block. Exception or status code returned is data
DWORD 0. Data: 0000: 05 00 00 c0 ...À
CAUSE
This behavior may occur if you use certain types of network adapters. The
network adapter driver may return description strings to the
CollectTcpIpPerformanceData function that do not contain null terminators.
The sprintf function copies the description strings to a local variable.
However, the sprintf function does not check to make sure that the strings
are not too large for the local variable to hold. As a result, a buffer
overflow may occur. Because the buffer is stored on the stack, the stack
becomes corrupted. This corruption causes an access violation.
