  • Hi,

    Did you configure legacy IPsec for the XP computer, and connection security rules for the Windows 7 computer?

    Note that connection security rules are ignored by XP. Also see the table at http://technet.microsoft.com/en-us/library/dd125389(v=ws.10).aspx for details on expected behavior. Computers running XP also have some issues. A connection between two computers running XP or between two computers running Windows 7 should work as expected, but when you mix the two operating systems the behavior can be unexpected because you are applying two different kinds of IPsec rules (Vista, Win7, and Win8 use AuthIP but XP does not).

  • Hi Carlos,

    To configure these policies in Group Policy, see http://technet.microsoft.com/en-us/library/dd314176.aspx. There are instructions here for both Vista (which applies to Win7 and Win8 also) and XP. The section for XP is called "Configure the XP IPsec Secure GPO."  The instructions assume you've already created OUs using this procedure: http://technet.microsoft.com/en-us/library/dd314169(v=ws.10).aspx.

    The two places where the different polices are configured in the Group Policy Editor are shown below:

    Thanks,

    -Greg

  • Hello Greg
    really appreciate your help, I've been reviewing the different documentation that you sent me, but I still have the problem now and I have also reviewed the computers that have Windows 7,

    any idea?

  • Hi Carlos,

    When a connection is made between two computers using IPsec, this connection can persist. Starting and stopping the IPsec service will prevent established tunnels from persisting when conditions change:

    net stop policyagent and net start policyagent

    To do this in a single command, type: net stop policyagent && net start policyagent

    You can also set up the IPsec security monitor and watch the connection.

    • Click Start, click Run, type MMC, and then click OK.
    • Click File, click Add/Remove Snap-in, and then click Add.
    • Click IP Security Monitor, and then click Add.
    • Click Close, and then click OK.

    See http://technet.microsoft.com/en-us/library/cc787758.aspx

    I hope this helps,

    -Greg


    P.S. Ping will always give confusing results if you are using two computers on the same subnet, because broadcasts occur that affect results. File sharing is the most dependable thing to test.
