Hi All,
I have an application with which I can connect to an Mobile Data Device via RAS connection. I create an DUN and use RAS calls to establish an internet connection using my Mobile Data Device.
I have developed the application using VC++ 2005 on Vista.
One of our customers (customers of the firm for which I work for) have reported an "Black Screen" on returning from hibernate mode and because of this black screen, he is not able to log-on. The environment is Vista Enterprise SP1 on Dell Latitude Tablet PC.
The work around is that the user has to log-in in "Safe Mode", delete "Rasphone.pbk" (which my application created while making connection) and then he is able to log-in.
I happened to have a look at the Rasphone.pbk that was "possibly" causing this issue but found nothing unusual or no corruption in it. This behaviour is inconsistant.
Have you guys faced similar issues where-in you observed an "Black Screen" on returning from hibernate/sleep/restart on Vista Enterprise SP1 and which goes away on deleting the Rasphonebook.pbk (after logging onto Safe Mode).
Unfortunately, the customer has not shipped any RAS Logs to share with you guys.
Thanks & Regards
