Windows 2008 R2 - Source: Schannel, EventID: 36888, Task: lsass.exe


  • Hi,


    i have installed on the Windows Server 2008 R2 a Exchange 2010 and after i switch this Server to the front (OWA and Outlook Anywhere) i got every secound this error in the eventlog. i think this Problem must have a contact with IIS and RPC over HTTP or the OWA, but everything works fine, so i don't find a direct Problem, only the Eventlog will be flooded. 

    - <Event xmlns="">
    - <System>
     <Provider Name="Schannel" Guid="{1F678132-5938-4686-9FDC-C8FF68F15C85}" /> 
     <TimeCreated SystemTime="2010-06-21T11:51:40.956846100Z" />

     <Security UserID="S-1-5-18" /> 
    - <EventData>
     <Data Name="AlertDesc">10</Data> 
     <Data Name="ErrorState">1203</Data> 

    kind regards

  • Hello OPERATOR76,

    Typically, this error may result from an SSL/TLS problem.
    Please have a look at this thread:

  • Hello,


    i think the Problem can be the woldcard certificate for smtp, iss, pop and imap. the console told me, a wildcard certificate can not be used, so i use now the servercertificat itself and i'am waiting now for the next error in the eventlog, if there is no tomorrow i think i fixed it with this setting. 

    My Wildcard certificat looks like this:

    AccessRules        : {System.Security.AccessControl.CryptoKeyAccessRule, System.Security.AccessControl.CryptoKeyAccessR

                         ule, System.Security.AccessControl.CryptoKeyAccessRule, System.Security.AccessControl.CryptoKeyAcc


    CertificateDomains : {*}

    HasPrivateKey      : True

    IsSelfSigned       : False

    Issuer             : OU=Equifax Secure Certificate Authority, O=Equifax, C=US

    NotAfter           : 28.03.2011 15:52:20

    NotBefore          : 27.12.2007 15:52:20

    PublicKeySize      : 1024

    RootCAType         : ThirdParty

    SerialNumber       : 011001

    Services           : IIS, SMTP

    Status             : Valid

  • Signing into Lync connected to Office 365 causes the issue.  I reproduced the problem several times by exiting and then starting and by signing out and signing into Lync Online. The Process ID indicates LSASS.EXE but the problem is caused by Lync.
