Cannot connect to LogMeIn servers

clock April 15, 2014 07:46 by author Ashwin Pai

LogMeIn clients displays the following message

Cannot connect to LogMeIn servers.  Confirm that your computer is set to the correct date.

If this is an older Windows XP or Windows Server 2003 , it is probably because the Root certifiate for Microsoft has expired.

To update the root certificate you can do it from the following link.

http://download.windowsupdate.com/msdownload/update/v3-19990518/cabpool/rootsupd_afc57447f7caadd3253333e35777fcd.exe

You can additionally enable the component " Update Root Certificate" in Add/remove programs >>Windows Components.

 

If it helped would appreciate a rating star.

Event ID: 27 While processing a TGS request for the target server krbtgt

clock May 12, 2012 12:59 by author Ashwin Pai

While processing a TGS request for the target server krbtgt XXXXXXXX
did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 8).
The requested etypes were 18.  The accounts available etypes were 23  -133  -128  3  1.

Event Type: Error
Event Source: KDC
Event Category: None
Event ID: 27

The cause of the event is that the client requests a service ticket with a etype 18 (aes256-cts-hmac-sha1-96), which is not supported by Windows Server 2003 but supported by Windows Server 2008 R2. If the Kerberos authentication works properly, you can safely ignore the events. It just informs the clients what etypes it supports.

For more information, please refer to the following articles:

The security principals and the services that use only DES encryption for Kerberos authentication are incompatible with the default settings on a computer that is running Windows 7 or Windows Server 2008 R2
