New install: Event Log - Schannel Event ID: 36888

I am in the process of setting up a Microsoft TMG server on a new Dell PowerEdge R610
I have installed Windows Server 2008 R2 Enterprise, Exchange 2010 Edge Transport Service, ForeFront 2010 for Exchange and finally TMG 2010 as per the TechNet TMG installation guides. All the latest updates have been applied including Exchange 2010 rollup 1.
Around the point at which I installed Exchange 2010, the system event log started filling up with the following entries:
Source: Schannel
Event ID: 36888
User: System
Message: The following fatal alert was generated: 10. The internal error state is 10.
TMG seems to be working correctly - proxy, web filtering, server publishing etc. However I can access any HTTPS websites from the TMG server, this seems to be causing problems with Windows Update/Forefront 2010 updates.
I have installed two SSL certificates - one was requested from our internal certificate server and I have Exchange enabled that certificate for SMTP. The other certificate is our public SSL certificate we use for website publishing - and ultimately SMTP but in case their were problems with the intermediate certificates I haven't yet enabled it for SMTP.
I'm having trouble finding any useful information about the Schannel error - can anyone help?
Thanks.

Uncheck the TLS (transport layer security) options in Internet Explorer and check.
a.       Open Internet Explorer and click on Tools.
b.      Click on Internet Options and click on the advanced tab.
c.       In Security, make sure that the TLS is not checked.
d.      Click on Apply and then click Ok.
e.      Now try to play the game and check.

Contract Manager 14, new install, cannot log in

I have tried to install CM 14 and can't seem to login. I keep getting "The user id or password you entered is no valid".
I have a Win Server 2003 R2 Stnd Edition SP2 test server with a new standalone CM 14 Biz Intel Pub Edition install with JRE 6-24, Weblogic Server 11g (10.3.4), and SQL Server 2005.
The startWeblogic.cmd seems ok.
Weblogic Server 11g Admin Console seems ok with data sources and expedition deployment State: Active, Health: OK.
admincm.cmd seems ok and Primavera Administrator opens ok with exp.sql login/password.
When I use http://<servername>:7001/exponline/adminlogon.jsp locally (and remotely on the same LAN), the exp.sql login/password fails.
Also when I use http://<servername>:7001/exponline/logon.jsp locally (and remotely on the same LAN), the exp.sql login/password fails.
What am I missing?

Hi Nikki and others,
I have tried your suggestions Nikki and failed.
If I look inside SQL Server 2005 under Database EXPADMIN > Security > Users I have dbo, exp, guest, INFORMATION_SCHEMA and sys and the same for Database CMDEMO. Under Security > Login I have exp and sa amongst others. There are no EXPADMIN or ADMIN users/logins inside my SQL Server 2005.
I have followed the Installation and Configuration Guide for Microsoft SQL Server, but when I reach Page 110 I cannot login.
What am I doing wrong?
I do not understand why the exp login with password sql is not working?
With Thanks and Best Regards,
Michael

Hi Jan,
Based on my research for the Event 36888, the issue may be caused by not standard or corrupted behavior of web browsers or users, such as user use HTTP protocol to access Exchange service which is a SSL site on port 443.
Please check whether there is a HTTP redirect configured in your IIS Manager of Exchange server. Also reset web browsers to have a try. Here are some similar thread for this issue:

"Flash out of date" comes up, new install, and will not accept Password for install? Next step?

"Flash out of date" comes up, i do a new install, the log-in and password windows pops up, I type in password and it will not accept.
I have changed password, confirmed password, rebooted several times, and it still will not re-insall new version.
I am stuck.
HELP!

This password prompt is presented by your operating system, and is intended to keep you from accidentally installing software.
If this is your personal machine and you don't need a password to log into the computer when it first starts up, you can probably leave the password blank and click OK to get past this prompt. If this is your personal machine and your normal password isn't working, check to make sure that CAPS LOCK is off, and type the password carefully.
If this is your work machine and it's asking for an Administrator password, well, you'll need to have a conversation with your friendly IT person.
If you're still stumped, you may need to reset the password on your Mac:

Event log - Schannel Event ID 36888

Hi
I did a migration from SBS 2003 to SBS 2011 and all went smoothly. After migration I started to notice these errors popping up in the system log.
Schannel Event ID 36888 :"the following fatal alert was generated: 10. The internal error state is 1203."
I have scoured the forums and tried everything I could, from upgrading the sharepoint to checking exchange. It is not affecting the server performance in any noticeable manner but it is filling up the logs and I would rather know what is causing this other
then just suppressing the log?
It could be something mayor that I am missing

Hi Jean H. Marais,
Just additional. This error (Event ID 36888) occurs if a user tries to access a web site using HTTP but specifies

The computer consistantly freezes for about one to two seconds over and over, making it difficult to navigate through web pages. I have looked at the Event log and this is the only consistent error that has taken place that falls in line with this
issue. I have tried changing the Security in Internet Explorer and tried every option for SSL and TLS and removed all history and cookies after each change, as well as restarting my computer, and still to no avail. Please help! Thank you.

Event ID 36888 - Schannel - A fatal alert was generated and sent to the remote endpoint.

Exchange 2013: 2 x multi-role in one DAG - on-premise
Performing remote mailbox migration using internet (*non-exchange web-based tool*), to ship data from cloud Ex2010 server to Ex013 on-premise.
Have multiple failures when doing the mailbox data copy - my migration tool error code tells me that:
This error indicates that we were unable to authenticate to the source or destination mailbox and retrieve a list of folders when given 15
minutes to complete these operations. This may be because the source or destination is unusually slow, has a very large number of folders, or due to "hanging" networking calls.
Some mailboxes are copying, but around 80% are not. Checked all permissions and other factors.

Hi Simon
I opened a SEV B case today. Appears to directly reflect the amount of load i put through, in terms of data being shipped with our migration tool. That tool is basically logging into each mailbox using a superuser account and populating
it with mail and calendar data form a source cloud mailbox. No fancy co-existence or online move requests.
All throttle policies are removed. Attempting to migrate more than 20 mailboxes at a time results in the System Event log being filled with the Schannel error above. Reducing the amount below this still shows the errors appearing, but not enough
to stop mailbox data being shipped and the migration tool suffering a stop error.
I will update the thread tomorrow when i speak with the engineer. Surprised noone has had any input so far.
I have the same problem, here is some data. I have two exchange profiles and the 2nd one stops logging in after this error starts. I have to reset the wireless connection and restart outlook to clear the situation.

SChannel - Help with Error # 20 (Event ID # 36888)

Was hoping somebody could help me understand what's causing some SChannel error 20 events I'm seeing in system event logs.
Running Server 2008 R2 as IIS web servers, have a commercial wildcard SSL certificate in use on multiple sites and we use IIS Crypto's "best practice" settings.
Majority of our customers, monitoring apps and SSL labs report no issues with HTTPS, however we have one customer with a data-center hosted application which sometimes connects flawlessly, yet other times causes our server to generate fatal alert 20 and
reset the connection before it even reaches IIS.
Can't see any pattern to these issues and very little of the discussion online about error 20 seems to fit here as it mostly relates to invalid server certificates, low-level development with SSL or other "consistent HTTPS failure" scenarios while
ours is more intermittent.
Reading up on error 20 suggests it should be indicate a "bad record mac", where I'm reading the mac to be a checksum of the SSL message suggesting the message may be incomplete, altered or incorrectly signed -- but not being an expert on either
schannel or crypto I could be misunderstanding what this means.
Attempted to find more detail regarding the internal error state value, with very little luck.
Tried enabling SChannel logging for errors and warnings (3), but that's not provided any more detail before or after this event.
Right now I'm not entirely sure what's causing the problem which makes it even harder to look at solutions, so if you have any questions or need more detail let me know, will try and keep an eye on this for the next few days.

Hi twrty,
This error can caused by many reasons, typically reason I experienced such as ,Incorrect certificate bind with HTTPS Port 443, enabled Cert Authentication wrong certificate
was used ,certificate on TMG server is revoked and has not validity, SSL handshake failures between client and server also can cause these events, please check all this above conditions and disable the port 443 related security of your firewall then monitor
again.

Event ID 36888. The following fatal alert was generated: 51. The internal error state is 1306.

I have searched on TechNet as well as googled it. I have not found too much information as to what specifically is the issue here. I do know that Alert 51 has to do with TLS. I have adjusted the registry to enable logging for TLS 1.0 (client and server),
but do not know exactly the version Lync 2010 uses.
I have also removed an old certificate. This did eliminate an earlier Schannel error message. Yet, this particular one, 51 internal error state 1306, kept coming back.
Although I can disable the logging, I prefer to know what specifically is going on and what is generating this error message. Does anyone have any ideas?
TIA

Hi,
Check the list of post installation steps:
http://www.saptechies.com/post-installation-steps-for-ecc-60/
From my point of view basic post installation steps are:
- Installing SAP License (from http://service.sap.com/licensekeys)
- Setup TMS (STMS)
- Import profiles (RZ10)
- Client Copy (SCC*)
- Create users (SU01)
However further many steps are required as per your requirements. Cehck the link for more detailed steps.

Cannot add new iCal events on my iPhone 3G.

My iPhone 3G has stopped saving new iCal events. I can still set up new events in iCal on my laptop, and they'll sync over to my iPhone, but new events won't save when entered into iCal on my iPhone. Any idea what's wrong and how to fix this?
BTW, I just got rid of a MobileMe account. I never ended up using MobileMe, so it doesn't seem like that should be the issue here, but I noticed that some other folks have had iCal sync issues with MobileMe, so I thought I'd add that info.

In other words, it's hacked.
Sorry, you can't get help here.
Say for an instance, that it wasn't hacked. Would you suggest to just wipe and restore it?

Create new iCal event from contents of mail uses wrong date

I received an email today with an appointment using the date "6/3/2010 at 4PM". Being from the US, it is obvious to me that this meeting should occur on June 3, 2010, but when I attempt to create a new iCal event with this date it creates the event on March 6, 2010. Even more confusing is that when I choose "Show this date in iCal" it highlights March 7, 2010!
My question is:
Shouldn't the system default to a month/day/year date preference everywhere when I've selected US English in the internationalization preferences pane?

have a very similar question: is there somewhere an application where I can, when receiving an email, put it into iCal so that I am reminded about it in a week or something?

But recently when I "Create New iCal Event" from an email, and click "add to iCal" the window closes but the event doesn't show up in iCal. I can still add events by clicking on a calendar date in iCal and typing them in, but the link between Mail and iCal seems to be broken. How can I fix it?
Could this be related to how Firefox recently broke? Foxfire will not save bookmarks any more, either, I click on "Bookmarks," then "Bookmark this page". The window closes but the bookmark does not save. Also, the forward/backward browser arrows no longer work on Foxfire.

Could you be more specific? What happens (or fails to happen?)
