It is possible to compromise your computer (when it is not patched etc)
in this case, hackers will have access to your internal network, will know your passwords and will be able to access your domain with your credentials.
they can sniff local network from your pc and get passwords from your collegues.

it is recommended to have private ip address on your pc, and allow only remote desktop through your company firewall and only from limited number of IP addresses (like your home, home of your girlfriend etc)

Hey Thanks for your help but it would be great if you can provide more information like
a) Suppose the public ip i have is 212.2.x.2 . Now a friend of mine knows this.
i understand that By running nslookup he can know the dns details
b) By running apllication like superscan & whois he can know ports and location

What more can he deduce? suppose if my remote desktop ports are open, which software can help him guess my password for login.

I would appreciate a very detailed and precise answer
Thanks

when your remote desktop is open your are vulnerable to brute force attacks and password guessing.
most likely your working under administrator account ;)

then in case of some 0-day vulnerability in Windows your box can be easily compromised (remember I love you virus, Sasser, etc), because Microsoft is not fast enough in releasing patches.

but besides that your friend will not gather much info about your network
