W2000 Server Sp3 with IE 6.0 Sp1
XP Pro with IE 6.0
Vendor status :
MS is investigating the issue but as they spent months to just acknowledge
it I decided to publish it
Description :
With Internet Explorer you can make calls using netmeeting ,
navigating to callto Urls . On the systems tested if you try to
navigate to a specially crafted callto url Windows halt with a
Kmode exception not handled . I can´t reproduce this always,
particulary not after rebooting from the system halt , but the issue
was confirmed in two different computers .
I am afraid I can´t give any debugging info cause no causing module is
shown in the BSOD .
