Token problem between 2 computers in the network.

NTFSD
1

there are 2 computers in the LAN.
When Client access the files of the share in the Server, I can get the
impersonation token
in the Server normally.
But I find a problem here. I double click the shared file,such as
EXAMPLE.TXT,modify some contents,
and save it.I can catch the MJ_WRITE operation in the server,and
impersonation token also.and I open
the same file as fast as I can ,and modify and save it.This time, I get the
MJ_WRITE operation,it’s
ok.but when i query the thread/process token, it is PRIMARY TOKEN! How does
this happen? I am confused.

Any suggestion ?
thanks in advance.

Regards,
Ming

SRV only impersonates during most IRP_MJ_CREATE and some
IRP_MJ_SET_INFORMATION calls.
