CAUSE
There is a problem is NDIS.SYS that causes Windows NT to attempt to close a
Windows NT file handle twice when NdisOpenFile and NdisCloseFile are
called. Closing a handle a second time causes undefined results. If the
handle being closed a second time is in use by another driver, the results
are unpredictable, but may include a system hang or STOP message.
The following network card drivers make calls to the NdisOpenFile and
NdisCloseFile APIs, and therefore may indirectly cause the symptoms
mentioned above.
ANDTOK.SYS
F30N3.SYS
F70N3.SYS
IRMATRAC.SYS
NCRTOK.SYS
MDGMPORT.SYS
NE3200.SYS
NETFLX.SYS
PCIMAC.SYS
PRONET16.SYS
TCTOKNT.SYS
UBNEI.SYS
NOTE: The problem is in NDIS, not in these drivers. They are listed here to
help identify systems that may exhibit the symptoms mentioned above.
RESOLUTION
To correct this problem, upgrade to Windows NT 3.51 (if you have not
already done so) and install the latest U.S. Service Pack for Windows NT
version 3.51.
NDIS.SYS was corrected to close the Windows NT file handle only once.
STATUS
Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and
3.51. This problem has been corrected in the latest U.S. Service Pack for
Windows NT version 3.51. For information on obtaining the Service Pack,
