Active SNA Server Clients Do Not Appear in License Manager

• Microsoft SNA Server, versions 3.0, 3.0SP1, 3.0SP2, 3.0SP3, 4.0, 4.0SP1, 4.0SP2

SYMPTOMS

Connected SNA Server Clients do not show up in License Manager when the SNA Server has been be configured for "Per Server" mode. This does not affect SNA Servers configured for "Per Seat" mode.

CAUSE

In "Per Seat" mode, when a new client connects, SNA Server calls the Windows NT License API, NtLicenseRequest(), and when a client disconnects, the NtLSFreeHandle() is called. When SNA Server is configured for "Per Server" mode, at startup it reads the number of licenses from the registry and, then SNA Server enforces this number. In this mode, SNA Server will never call the Windows NT License APIs.

SNA Server has now been changed to call the Windows NT License APIs when running in "Per Server" mode.
