Impersonation Question

I have 2 machines on the same lan. Neither one is on a domain. Lets call
them computer1 and computer2.

Computer1 has a user/password called Computer1User /Computer1Password


Using the LogonUser API in advapi32.dll, is it possible for computer2 to
impersonate the local user in computer1?

I am calling something like the following from computer2, which always
fails.

LogonUser("Computer1User", "Computer1", "Computer1Password",
LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, token)



Any Ideas? Is what I am asking even possible?

Thanks
 
Hi Ryan,

For LogonUser API, it can only take the following kind of accounts as input:

**a local account of the local machine

**a domain account of the domain this machine belong to

You can not call logonUser API against a local account on another remote
machine.

for your scenario, if the two machines are not in the same windows
domain(can not use domain account), you still have the following options:

1. create two duplicated account(with identical username, password ) on
both machines. Thus, you can call LogonUser api against
"computer1\username" on computer1, and when you access computer2, it will
autoamtically map your security context to "computer2\username" account

2. If what you want to access remotely is only NTFS fileshare, you can
create a mapped drive on computer1(linked to a share folder on computer2),
thus, you can provide the credential info(of an account on computer2) in
the mapped drive setting.

How do you think?

Sincerely,

Steven Cheng
