SYMPTOMS
There is a bug in the BROWSER.SYS driver that can occur when processing an illegal datagram on streams transports. If the datagram passed in is shorter than will fit in a valid transaction Server Message Block (SMB), the browser checks beyond the end of the buffer, possibly doing access violation.



STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem was corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
