SYMPTOMS
If both the SnaServer service and the Snabase service are configured to start automatically in the Windows Services utility, an EventID 39 gets logged in the Windows Application Event log:

Event Id:39

Source:WinMgmt

Type:Error

Description:

WMI ADAP was unable to create the object

Win32_PerfRawData_SnaServr_SNA3270ResponseTimes for Performance Library

SnaServr because property PercentResponsesThreshold4 already exists



CAUSE
Windows Management Instrumentation (WMI) has a problem in the generation of performance counter objects. WMI removes the characters when it generates an object name.

328152 How to Obtain the Latest Host Integration Server 2000 Service Pack



WORKAROUND
If the SnaServer service is configured to start manually, the error doesn't occur.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Host Integration Server 2000 Service Pack 1.



MORE INFORMATION
Review the relevant section of SnaPerf.ini below. Because the characters have been removed from the WMI Perfmon object name, that name has lost it uniqueness and a duplicate name error (Event 39) is generated:

SNA_0160_002_NAME=% Responses < Threshold 4 SNA_0160_002_HELP=The percentage of responses falling between the third and fourth time thresholds. An emulator must support RTM for these counters to be incremented.

SNA_0170_002_NAME=% Responses > Threshold 4 SNA_0170_002_HELP=The percentage of responses falling above the fourth time threshold. An emulator must support RTM for these counters to be incremented.

This problem is resolved by renaming the object name as:

SNA_0170_002_NAME=% Responses > Threshold 5

To apply the new counters do the following:  Use the Windows Services utility to stop the SnaServer service. An a command prompt, type the following to unload the SnaServer performance monitor counters:

unlodctr snaservr

 Copy the new Snaperf.ini to  \System\Snaperf.ini. At a command prompt, type the following to reload the SnaServer performance monitor counters:

lodctr snaperf.ini
