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

3CX phone provides a free softphone for the Android & Iphone.  However configruing it for another Voip provider can be some what challenging.

With a lot of help & patience from Mark at Apptix Voice & a lot of trial & error we got it working with their Service.

The instructions at the link below , illustrates how we got it working with Apptixvoice , but presumably it should also work for other non 3CX Voip providers with a little tweaking

Note:  Your ISP or Cellular services provider may specifically block Voip Sip traffic.

Thanks Mark!

That's it . You may or may not have to restart the website , I did not have to.

When you install SMTP on Windows 2008 Server , SMTP logs may not be getting generated. Websites may or may not be sending out emails & when you click on Current sessions in IIS 6.0 manger you get the message " No such interface supported".

While not obvious the ODBC Logging module a role service in Server Manager needs to be installed.

Windows 2008 IE 7 cannot download files.
 
In IE 7 the default security settings typically allows you to download files. On Windows 2008 IE7, the default security settings for the Internet Zone are high & File download is set to disable. You need to select Custom levels &  & enable File download.

This one drove me crazy. Many help articles start with  " start adsiedit and browse to CN=Configuration CN=Services ....." . I could not see CN=Configuration to save my life.

After hours of hair pulling I found this article Thanks David

Solution: This worked for me

http://blog.ronnypot.nl/?p=212

There are many complicated technical explanations solutions & Guides to resolve this.

But if you are like me and just want to solve the problem & move along. This is what you need to do .

1. backup the transaction logs ONLY

2. Backup the database ( Full ) for safety

3. Shrink the database

4. Shrink the files.

Done

Side Note: If you run a maintenance plan regularly to back up the transaction logs & databases you will not have to learn this the hard way  as I did.

1. Modify  Global settings

Organization Configuration->Hub Transport->Global Settings->Properties of Transport Settings
Modify   transport send/receive limits.

2. Modify Send Connector

Organization Configuration->Hub Transport->Send Connectors->Properties of Default Send
Modify send connectors default maximum message size

3. Receive Connector

Server Configuration->Hub Transport->Receive Connectors Pane->Properties of Default <hostname>
Modify receive connectors default maximum message size

The issue has been resolved.

1. In the Exchange MMC , under server configuration select Hub transport
2. in the action menu on the right hand side select " New Receive Connector"
3. Give it a name.  any name will do , we call it "Application relay"
4. In the next screen  Local Network settings
   4.a provide the fully qualified ( internal) dns name of the mail server
   4b. Edit the the receive connector binding & change the port to 26
5. In the next screen Remote network settings
   5a. remove the default bindings of 0.0.0.0-255.255.255.255
   5b. Add the IP address of the server running Backup exec, in our case 10.0.0.4
   This address is often the same as that of the Exchange server especially if you are running SBS
6. On the next screen New Connector you will be displayed a summary of your configuration which will look somewhat like this , click NEW to build it.
   Name: Application relay
   Type: Custom
   IP Address(es):
   (All available IPv4 addresses): Port 26
   FQDN: mailserver.domainname.com
   Remote IP range(s):
   10.0.0.4
7. IF all is well  On the next screen Completion you will be informed  so . click Finish
8. In the Exchange MMC double click the connector you just created &
   8a. select the Permission groups tab & check Exchange Server
   ( Note: if backupexec is not on the same server as the exchange server you may have to play around with this)
   8b. select the Authentication tab & additionally check off  Externally Secured
9. Go to Symantec Backup Exec & select E-mail alerts and Pager notifications from the drop down menu
10. Enable SMTP Configuration & fill up the information for your mail server , remember to specify port 26, Sender name & Sender email address. There is no need to Enable SMTP Authentication

That's it you are done.

 If you still cannot send email alerts , you will want to set the logging for the recive connector you just created to Verbose

You will find the log in the following folder.

Receive Connector logs are located in:
Exchange 2010: C:\Program Files\Exchange Server\V14\TransportRoles\Logs\ProtocolLog\SmtpReceive
Exchange 2007: C:\Program Files\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive
 

Send Connector logs are located in:
Exchange 2010: C:\Program Files\Exchange Server\V14\TransportRoles\Logs\ProtocolLog\SmtpSend
Exchange 2007: C:\Program Files\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpSend
