Schannel Error 36888

I am getting this Schannel Error 36888 over and over and over again. There NOTHING listed on the help site about it. I have no idea what it is, but my computer is crashing over and over again. I don't know if this is the reason, but it seems to be the most frequent event listed in the event viewer.

I restored my computer to the image I made after the initial installation back in July, and did this only after going back to restore points to 12/6/09.

It does not seem to be a Windows O/S issue or else these various restores would have fixed it. Nothing else has changed though. No new hardware added and any external devices I did have connected, I have disconnected to rule them out. All I have connected is one external hard drive (which I need for my backups) and the keyboard and mouse.

The computer goes to a blue screen, usually after doing something like opening Windows Explorer or something like that. Just sitting idle, it doesn't seem to happen. Or at least not as often.

What is Schannel Error 36888. I found posting on different sites but none that are conclusive or tell me what EXCATLY to do about it.

Getting the same error.  Just installed Trial Version of Outlook 2010 and noticed the message.

The error occurs when I allow Outlook to set up e-mail accounts on its own.  The first try is on a encrypted connection which fails, then the option to use an unencrypted connection succeeds.  The error happens during the encrypted attempts and occurs 3 times in succession.

My POP3 server just uses a password, so it seems the attempts to use a encrypted protocol is involved.  But maybe someone who understands more about how it works will know what type of scenarios might generate such an error.

Also I notice if I let Outlook set up the accounts, it will succeed using the incorrect server name.  Mine are pop-server instead of just pop, but Outlook sets it up anyway.  But e-mail access does not generate the error even using the wrong server name.

    Hello Albert,

    Thank you for replying.

    I do understand that security is important.

    Regarding Schannel, it is one of the Security Support Providers. The Windows operating system implements the TLS/SSL protocols as a Security Support Provider SSP, a dynamic-link library (DLL) called Schannel that is supplied with the operating system. You may refer to the "Schannel SSP Architecture" section of the article below:

    http://technet.microsoft.com/en-us/library/cc755284(WS.10).aspx

    I would like to know, which security software you are using?

    In case you are using McAfee, Schannel Error 36888  is expected behavior because McAfee Vulnerability Manager (MVM) is attempting to identify system services and ports, as well as determine the vulnerability status. The Schannel errors are written to the Windows Event log and can be many thousands of events, depending on the scan configurations and number of scan targets.           

    Workaround

    Use the steps in the following Microsoft article to disable the event logging for Schannel: http://support.microsoft.com/kb/260729/en-us

    Note:

    This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

    You can use the following link in order to back up and restore the registry in Windows: http://support.microsoft.com/kb/322756/

    Hope the information provided is helpful. Do let us know in case you need further assistance.

    I fail to understand how a Microsoft Support Engineer can seriously advise to uncheck all TLS options in Internet Explorer. Security is not important? Are we going back to SSL? Really...
