- Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS
========

When you run Windows NT Server 4.0 with File and Print Services for NetWare, the
following stop error message may appear in Fpnwsrv.sys during a burst mode
read:

  STOP: 0x0000003F (0x00000000,0x00000000,0x00000000,0x00000000)
  NO_MORE_SYSTEMS_PTES

CAUSE
=====

In certain error conditions, Fpnwsrv.sys does not unmap a nonpaged MDL when it
is finished using it. This error can occur during large burst reads when a file
is closed before the read is complete.

following fix, or wait for the next Windows NT service pack.
