SYMPTOMS
When you run Performance Monitor to track the performance of IP counters, the IP counter disappears. No error messages are displayed, but the following message may appear in the Event Viewer:

Open of IP failed. The IP protocol table full.

Event ID 4185

Source: TCPIP.SYS

Type: Error

This problem may be intermittent.



CAUSE
This problem occurs due to the RPC service of Performance Monitor sending multiple load/free library calls to the file INETMIBL.DLL. The file does not close its handles when it receives a termination call as the result of a free library.



STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem has been corrected in Windows NT Workstation and Windows NT Server version 3.5.
