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="http://schemas.microsoft.com/win/2004/08/events/event"> - <System> <Provider Name="Schannel" Guid="{1F678132-5938-4686-9FDC-C8FF68F15C85}" /> <EventID>36888</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x8000000000000000</Keywords> <TimeCreated SystemTime="2010-06-21T11:51:40.956846100Z" /> <EventRecordID>4086</EventRecordID> <Correlation /> <Execution ProcessID="496" ThreadID="6304" /> <Channel>System</Channel> <Computer>EXCHANGE2010.domain.local</Computer> <Security UserID="S-1-5-18" /> </System> - <EventData> <Data Name="AlertDesc">10</Data> <Data Name="ErrorState">1203</Data> </EventData> </Event> kind regards Alex

Hello OPERATOR76, Typically, this error may result from an SSL/TLS problem. Please have a look at this thread: Schannel Fatal Alert Error 48 http://social.technet.microsoft.com/Forums/en/windowsserver2008r2general/thread/74cfe52a-724e-4338-bd91-f2de99604523 Best regards, Harry This posting is provided "AS IS" with no warranties, and confers no rights.

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 essRule} CertificateDomains : {*.xxxxx.com} 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 Subject : CN=*.xxxxx.com, OU=IT, O=My Comany, L=xxxx, S=xxxx, C=AT Thumbprint : xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

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.
