SYMPTOMS

Appendix C of the SNA Server "Reference Guide" describes SNA Server registry parameters that can be used to alter the default behavior of SNA Server. These parameters are configured in the following registry key:

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/SnaServr/Parameters

The Reference Guide describes these parameters as supporting "YES" and "NO" values. However, when most of these parameters are added to this registry key, the feature becomes enabled even though the registry value may be set to "NO".

CAUSE

The SNA Server service checks for the presence of these settings within the registry to determine whether to enable them or not, even if the entry is set to "NO". So, the Reference Guide incorrectly defines the method used to enable and disable these settings.

RESOLUTION

If the following entries are present in the SnaServr/Parameters key, they are enabled, even if set to "NO":

NOTERMSELF
NORETRY
ALLOWBBRQE
NO4004
NO400D
NO2001
CLEANUP
ALLOCINACT
NOINITCNOS
NOPWDSUB

SNA Server 2.11 only:

FNA_SUPPORT
HNA_SUPPORT

To disable the above settings, the registry value should be removed and the SNA Server service must be restarted.

If the following entries are set to "NO" (all caps), the entry is disabled. If they are set to any other value, or are not present in the SnaServr/Parameters registry key, they are enabled:

RETRYCNOS
RENEGLIMITS

If the following entry is set to "YES" (all caps), the entry is enabled. If it is set to any other value or is not present in the registry key, it is disabled:

NONOTIFYRSP

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11, 3.0, and 4.0.
