    "Ports found to be OPEN were: 21, 23, 80"

    Holy Crap!!!

    21 = FTP
    23 = Telnet
    80 = HTTP

    If I knew your IP address (which bad people will find soon enough by randomly scanning a range of ip addresses) - I could open a command prompt on your pc by the telnet command - put whatever files I want to on your hard drive via the ftp command - and run a web server on Port 80.

    You're screwed dude.

    Did you mean to run these services (http/ftp/telnet) on your PC?
    Try: http://127.0.0.1 (Your PC) to see if a web page is displayed.

    Since port 135, 137, and 139 are not open - I suspect it's your router/modem instead of your PC reporting these open port values.

    Maybe it is the router supplied by your ISP running these and I would contact them ASAP to close the ports. Ask them if you can replace their router with a router of your own like a linksys.

    The logmein software you have loaded could also be listening to those ports. Could be normal - but anything that leaves you that open is not good and could be bypassed.

    Hi stan0614,

    So, what would you recommed me to do to disable these ports?

    The latest news by from the link https://www.grc.com/x/ne.dll?bh0ciyl2 is like this....

    GRC Port Authority Report created on UTC: 2006-09-29 at 15:10:02

    Results from scan of ports: 0-1055

    3 Ports Open
    1053 Ports Closed
    0 Ports Stealth
    ---------------------
    1056 Ports Tested

    NO PORTS were found to be STEALTH.

    Ports found to be OPEN were: 21, 23, 80

    Other than what is listed above, all ports are CLOSED.

    TruStealth: FAILED - NOT all tested ports were STEALTH,
    - NO unsolicited packets were received,
    - A PING REPLY (ICMP Echo) WAS RECEIVED.


    Please recommed me with some good measures that I should follow before the "(which bad people will find soon enough by randomly scanning a range of ip addresses)" happens to me.

    sumesh,

    did you run the Microsoft Baseline Security Analyzer? Its a small proggy to help you finetune your pc security.

    It is available at http://www.microsoft.com/technet/sec.../mbsahome.mspx

    btw, were you browsing in other window while the online scan was going on?

    For closing the ports. click start>run>services.msc

    Port 21- Stop Application Layer Gateway Service
    Port 23- Stop Telnet
    Port 80-Stop Windows Media Services, World Wide Web Publishing Service and SharePoint Portal Server

    More info about the more obvious ports is at http://support.microsoft.com/kb/832017

    cheers

    Hai Chizra,

    Thanks for the post. I disabled the servies as you mentioned above, but what the strange thing was, I couldnt disable the telnet service. The telnet was already disabled. But one telephony service is still running, "which enables a remote user to log on to this computer and run programs, and supports various TCP/IP Telnet" is what mentioned in the properties of that telephony service. If I stop this service does the connection to internet stops completely?

    Please help me with this tooo!!

    Regards,
    Sumesh Paul.

    The snap shot of this particular services is attached.

    You may visit http://technet.microsoft.com/en-us/default.aspx

    and find more info about them.

    btw, i didnt do much, i just invoked my god (google) for it. And switching on/off services is trail and error. always recoverable.

    Om Shanti!

    Turning off telnet will NOT affect your connection to the internet.
    What is the status of using SHIELDS UP! now.

    Are the ports still open?

    Hi friends,

    I still have 3 ports open. The details about this is mentioned below.

    GRC Port Authority Report created on UTC: 2006-09-29 at 18:43:11

    Results from scan of ports: 0-1055

    3 Ports Open
    1053 Ports Closed
    0 Ports Stealth
    ---------------------
    1056 Ports Tested

    NO PORTS were found to be STEALTH.

    Ports found to be OPEN were: 21, 23, 80

    Other than what is listed above, all ports are CLOSED.

    TruStealth: FAILED - NOT all tested ports were STEALTH,
    - NO unsolicited packets were received,
    - A PING REPLY (ICMP Echo) WAS RECEIVED.

    I tried to close the telnet, which is already disabled, but still the port 21 is open.

    Am attaching a zip file of the this in detail.
