On Windows 98, there is no Event Logger as in Windows NT.  Hence, when
trouble occurs, the best the resource manager can do is to put up a dialog
box.

This particular message comes from an attempt to set up a shared memory file
for client/server communications.  When things are running smoothly, you'll
see a file called, %windir%\smartcrd.dat on your system.  Under normal
operations, this exists only when the Resource Manager is running.  If the
Resource Manager can't map to this file, you'll see this dialog.  We've seen
this in the past when the file gets marked "Read Only", or some other
software tries to protect system files from modification.

Subject:        Errors at ResManager startup

A security software company using our serial IFD-handler for a Windows 98
login application sometimes gets the following two dialog boxes at system
startup (before logging in):

DialogCaption:  Microsoft Smart Card System
DialogType:     MB_ICONSTOP | MB_OK
DialogText:     Com Responder could not map Connection File: The reference
(handle) is invalid.

(The last sentence, after the colon, was in local language, I've translated
it into English here)

DialogCaption:  Microsoft Smart Card System
DialogType:     MB_ICONSTOP | MB_OK
DialogText:     Com Responder Failed to start.

We know that our vxd starts off well before the scardsvr is started by the
...\Windows\CurrentVersion\RunServices registry key. The dialog boxes seem
to appear sometimes when the security software in question connects to the
card in our reader. This happens roughly at some time when the login dialog
box appears but before the user has logged in.

Apart from this, our IFD handler vxd has worked fine for almost a year with
a lot of applications.

The smclib.vxd version used is 4.00.950.
What are the possible causes of the dialog boxes? I haven't seen them at all
until now.

Kindest regards
