CAUSE

The event indicates that the server got STATUS_INVALID_PARAMETER (c0000008) when it called NtQueryInformationFile (bc0). This happens when the server tries to open a pipe named "\".

The problem is that if a Windows NT WOW or MVDM client application opens a file against a Windows NT server and that open fails, the clients WOW and MVDM both call a routine called IsCDROMFile that attempts to open and call QueryVolumeInformation of the file <server>\PIPE\ which fails on the server.

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 US Service Pack for Windows NT and Windows NT Advanced Server.
