This doesn't seem to be the case for Windows Security so I am very

This is my situation. Home LAN. I am defined on all systems with

GOVARNEY with administrator authority. The passwords on all systems

same. Systems are mostly XP Pro with 1 Vista Home Ultimate.

I am on system 1 and map a network drive to the C drive of system 2.
As I

to all
files and directories that GOVARNEY on system 2 has access to.

This is not the case. Why ?????

I suspect that your systems are still in the default state, set to use
or Guest only security model for network sharing. In this config, once
an account has authenticated for network login (share access) the
are transitioned to those of the Guest account and then all file/directory
access is authorized against that, so access is granted only where Guest
has permissions. When set to the classic sharing model things work much
as you expect as stated in your initial paragraph.
Although the wording varies some between OS versions, if you open the
local security policy (start/run gpedit.msc) and navigate to the local
options (Computer node, Windows settings, Security settings, Local policy,
Security Option) look in the network access policies for such as Sharing
and security model. In XP this was also available in the Folder option
at the bottom (off the Tools menu)
