Jai,

Someone hacked my system.I have SMTP/POP3 running on
Win XP and working on a LAN and have given permission
that any one on my LAN can create account.

What application are you using?  Exchange?  Something else?

Lastday someone created account and i got the message
of new account creation and when i checked i found
that he was trying mutiple SMTP connections TO&FROM
fake id. i got his ip.

Created account?  Did you get notification from the
app, or from the Event Log?  What type of monitoring
are you doing?

These multiple connections could be relaying, as with a
worm.

When i checked the logs from Eventviewer i found that
Administrator loggedin twice from two different ip
using the tlntsvr.exe service thts why i am thinking
that the ip was fake.

If the IP is fake, or spoofed, the login wouldn't have
worked, unless routers had also been hacked.

Is there any way i can find out how he got access and
how he entered through tht SMTP port and the history
tht wht he did on getting the cmd prompt or any other
tracing trick.

If it's a remote hack, there might be some info on the
system, but to be honest, it isn't really clear what
happened.  And where you look depends on what you've
got running on the system.
