    If a user has ESET Smart Security 4 installed on their computer and getting the sign-in error “80072745”, here is the solution:

    1. Right-click the ESET Smart Security icon in the system tray and select “Advanced Setup…”.

    2. Click on “Excluded applications” under “Protocol filtering” in the setup column tree.

    3. Locate and check Windows Live Messenger (msnmsgr.exe).

    4. Sign into Windows Live Messenger.

    Furthermore, after these steps are followed, sign out of Windows Live Messenger and put ESET Smart Security in “learn mode”:

    1. Double-click the ESET Smart Security icon in the system tray.

    2. Select “Setup”.

    3. Select “Personal firewall”.

    4. Select “Advanced Personal firewall setup…”.

    5. Change the filtering mode to “Learning mode” using the drop-down box and click OK.

    6. Sign into Windows Live Messenger again so that ESET can set the proper firewall entries for allowing the messenger to function. (Change the filtering mode back to the desired mode when finished.)

    If anyone uses a different virus software/firewall, try to locate similar settings dealing with this same protocol filtering and disable it.

    micro soft should pick it, and give the solution at one point click. or bring the new version of messenger without this problem, i.e immune to this problem.

    THanks for the tip but it doesn’t work.
    I formatted one of my computer purely for Live messenger 9 but to no avail.

    i just kept retrying, it seems like msn is lagging and or gateway having high latency.
