hi guys,

I got the following iussue here.

I have two Computers, both Win xp pro SP2
(no passwords for Administrator's account set).

I assume that no one has local access to the computer.
so the only way to get to the data(shares, ipc$) is by remote (home
network, internet)

When I try to establish a connection via ipc$ or a connection to a
network share , using the Administrator account
(e.g. with Sysinternals tools), Windows declines the connection.

If i set the same password on both computers, i can establish a
connection, use administrative priviliges, network
shares etc.

So my question is why should I even bother to set up a strong password
for my Admin Account (which can be
broken by BruteForce or Wordlist), when Windows denies any connection
with an empty password.
Wouldnt it be a lot more secure to configure a system without a Password?

Or is there any way to trick Windows into accepting a connection with an
empty password or to
run a programm from the command line without a password?

Your input is pretty much appreciated.
