SMTP server 2008 Not using TLS

I have setup a SMTP server 2008 and purchased a SSL cert for it. The cert is found in the SMTP properties. When i telnet to port 25 and do a helo starttls does come up. I am using this SMTP server for sever applications to send email only. I have restarted
services and checked the TLS boxes in the SMTP setup. I cannot get this smtp server to send using TLS. Port 465 is setup in the SMTP settings, default when you setup the TLS in the SMTP settings. How do i get the SMTP server to send using TLS? I have googled
until my eyes bleed. Any help will be greatly appreciated.
Thanks in advance for your help.
Thanks for your help

Ok i have fixed it but not sure why it is working. Both ports on the smtp server are now set to 25 and after sending an email and reviewing the header it appears that it is sending in TLS v01, as shown below. This tells me that the email was sent using TLS.
I did not think you could send TLS over port 25. Can someone explain please? Oh by the way i still cannot get 465 to work. The traffic is going out but i get no response from the rcpt side. Not sure why this is working. Any help greatly appreciated.
(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=OK)
Thanks for your help

Error attaching Adventureworks 2008 db to SQL Server 2008 [not R2]

Hi ppl,
I have SQL Server 2008[NOT R2] installed in my laptop [Windows Vista Home Premium, 64 bit].
There are 2 issues:
1. Downloaded the AdventureWorks 2008_SR4 from the link :
http://msftdbprodsamples.codeplex.com/releases/view/37109 .
but wasn't able to install it due to an error - database Installer stopped working and had to close the program.
Hence my friend installed it his laptop and sent me the .mdf and .ldf files.
2. I tried attaching the databases using SSMS2008, but it is showing Error:

I have checked the version of sql server opened in SSMS and it is 2008 itself
I cannot find any other Non R2 AdventureWorks file for 2008.
Any help would be appreciated greatly.
Thanks,
Chips.

Hello Chips,
database version 655 is SQL Server 2008, 661
is SQL Server 2008 R2, so your friend send you a database file of a newer version, which you can't attach to a older version. I guess your friend uses 2008R2, the database is upgraded automatically to this version.
Have a deeper look at CodePlex, Version 2008 is still available there.

How to make a DKIM signature for outgoing messages in Thunderbird (SMTP-server does not support DKIM)?

SMTP-server does not support DKIM signature.
How to make a DKIM signature for outgoing messages in the Thunderbird?

I'm not familiar with this particular use of the terminology.
Thunderbird has S/MIME support built in. You can add PGP support via the Enigmail add-on. Both offer the means to sign and encrypt messages.
I see add-ons to support the checking of DKIM-signed incoming messages, but haven't found any yet for signing.
Is it something that an email client is entitled to do? The Wikipædia entry says
<blockquote>Both modules, signing and verifying, are usually part of a mail transfer agent (MTA).</blockquote>
and that means a server, as opposed to a client (MUA).

Apple SMTP server IP not reverse mapped

I have discovered that the SMTP server that Apple is using to reply my outgoing iCloud email (17.111.211.51) does not have a valid reverse hostname associated with it. This causes some of my email to be rejected by other mail servers. I do know that some of Apple SMTP servers are correctly reverse mapped,. but not this particular one.
i.e.
host 17.172.220.237
237.220.172.17.in-addr.arpa domain name pointer st11p02mm-asmtp002.mac.com.
237.220.172.17.in-addr.arpa domain name pointer st11p02mm-asmtpout002.mac.com.
This seems to be an oversight bt Apple's network administarators. I'm hoping that this message can be forwarded to the appropriate dept.
Thanks!

Hello.
I'm hoping someone can help with a problem I've been having today.
I have a Gmail account which I use on my Mac (MacBook Pro, 2.4GHz Intel Core 2 Duo, System 10.6.8), my iPad and my ancient iPhone. Everything has worked perfectly for the last two years until today when it stopped sending e-mail from any device. On my iPad, it tells me that the SMTP server 'does not allow relay'. On my MacBook, it simply refuses to send it and prompts me to choose another SMTP server (which, alas, I don't have).
At any rate, here is a list of things I've already tried:
1. I tried switching my computer off and on again. This didn't work.
2. I have deleted the account (from both Mac and iPad) and set it up again. This didn't work.
3. I have deleted just the SMTP server details and re-entered them (both Mac and iPad). This also didn't work.
4. I manually changed the SMTP port to 25 and 587. This didn't work.
5. I have tried to send e-mail from a different WiFi network and from 3G (Mac, iPad and iPhone). This didn't work.
6. I have tried setting up a completely new Gmail account and using the SMTP server of that account to send messages. Bizarrely, this sort of worked: it allowed me to send a message, but the message showed up from the new account rather than from my primary account. However this is not an ideal solution. I would much prefer having a single e-mail account which both sends and receives.
7. I also tried a variety of other things, but nothing worked.
I fear the problem may actually be with Gmail, and not with any of the Apple products in question. I spent about an hour trying to contact Google, but I don't think they will get back to me.
If anyone has any brilliant ideas, I would be tremendously grateful.
All the best.
The issue is with gmail. There are 10 post already about this in the iphone forum.

VD-4280: The SMTP server cound not be connected to

I am trying to configure Email Notifications through OMS. When I hit the test button I get follwing message "VD-4280: The SMTP server cound not be connected to". I have given the correct IP address of our mail server for smtp Mail Gateway option. I have even added "OMS.VDM.SMTP.LINESEPARATOR=CRLF
" in omsconfig.properties file as advised by metalink note 302828.1 but still i am unable to get rid of the above message.

From the SQL*Plus prompt type "host" and go to an operating system terminal window. Can you ping the mail server?
Did you set the SMTP_OUT_SERVER = <port_number> initialization parameter?
Did you identify the mail server? For example:
ALTER SYSTEM SET smtp_out_server = 'smtp.psoug.org' SCOPE=BOTH;
Hopefully one of these will help.

Possible to run *own* Stratus server or *not* use Stratus for RTFMP?

Possible to run *own* Stratus server or *not* use it for RTFMP?
In other words, have Flash peers be able to talk RTFMP without needing to ever talk to Stratus server.
It may not always be possible to stay connected to Adobe's Stratus servers so this would be useful.
Possible? How?

Flash Player 10.1 beta supports nc.connect("rtmfp:"). a NetConnection connected in this manner can only be used for groups communication (NetStream for multicast and NetGroup) between peers on the local LAN, or for a NetStream that is to receive a pure IP multicast (no P2P or C-S at all). this is covered in the beta ActionScript reference page for NetConnection.connect().
note that this mode can't be used for 1-1 NetStreams, only group NetStreams and NetGroups.
in order for peers in the group to find each other on the local LAN, you must enable LAN peer discovery and add an IP multicast address to the groupspec. when using GroupSpecifier to make the groupspec for joining groups (recommended), that's the "ipMulticastMemberUpdatesEnabled" property and the "addIPMulticastAddress()" method, respectively. for example:
var nc:NetConnection = new NetConnection;
nc.connect("rtmfp:");
var gs:GroupSpecifier = new GroupSpecifier("com.example.chatapp/mychannel");
gs.multicastEnabled = true;
gs.postingEnabled = true;
gs.ipMulticastMemberUpdatesEnabled = true;
gs.addIPMulticastAddress("239.254.254.1:30000");
var ng:NetGroup = new NetGroup(nc, gs.groupspecWithAuthorizations());
var ns:NetStream = new NetStream(nc, gs.groupspecWithAuthorizations());
// ... add event handlers, wait for NetGroup.Connect.Success & NetStream.Connect.Success, then post and publish/play streams
in this example, i specified a group called "com.example.chatapp/mychannel", where P2P multicast and posting are enabled, where peers can discover each other on the local LAN and they use IPv4 multicast address 239.254.254.1 UDP port 30000 to do so.
things get really interesting when you connect to Stratus and enable the group server channel (to get auto bootstrapping) and *also* use LAN peer discovery so that peers on the LAN will be more tightly meshed than they necessarily would through normal group topology evolution.

SSIS Package developed in SQL Server 2008 R2 Using BIDS 2008 is not working in SQL Server 2012

I am working in a Product based company.
We have given a Pre-requisites to our customers like SQL Server version should be 2008 or later.
I have developed and deployed my SSIS package in SQL Server 2008 R2 with BIDS 2008.
I have used "Script Component" in my package.
We will take only DTSX package file to the customer places and run using SQL Agent Job daily.
Who are all(Customer Environments) using SQL 2008 or R2 my package is running fine.
Who are all(Customer Environments) using SQL 2012, I am facing the below issue
The component metadata for “Script Component, clsid {874F7595-FB5F-4OFF-9BAF-FBFF825OE3EF}” could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
Still the same package is running fine for some of the customers having SQL 2012.
I am getting the above error only for few customers.
Can someone please guide me how to proceed on this. Is there any solution to go without upgrading the package to SQL 2012. Because we need to maintain only one package for all customers

Hi Katherine,
I am just using the script component only for generating Identity column purpose. I will get the maximum count from the table and using this count value as Input (JurisCount in my below code) for script component and increment the counter for new records.
Finally I am mapping the Script component output value (JurisKey in my below code) to Key column of the table. That's all I am doing with Script Component.
Here is my Simple .net code
/* Microsoft SQL Server Integration Services Script Component
* Write scripts using Microsoft Visual C# 2008.
* ScriptMain is the entry point class of the script.*/
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
public override void PreExecute()
base.PreExecute();
Add your code here for preprocessing or remove if not needed
public override void PostExecute()
base.PostExecute();
Add your code here for postprocessing or remove if not needed
You can set read/write variables here, for example:
Variables.MyIntVar = 100
int counter = 0;
public override void Input0_ProcessInputRow(Input0Buffer Row)
if (counter == 0)
counter = Convert.ToInt32(Row.JurisCount);
Row.JurisKey = counter;
counter = counter + 1;

SMTP Outgoing Mail Server does not use password so I can not send mail..

Hi All
Can anyone help me with this?
My POP email accounts on Hosting.365.ie do not use a password to authenticate outgoing mail. They rely on a prior authenticated download to enable the outgoing mail server.
On my MacBook Pro there is an option in the SMTP server settings under authentication for "none' and all my accounts work perfectly on the MacBook.
However my iPhone4 (brand new) and iPad (both up to date) there is no option under the SMTP server settings for "none". I think this is the root of the problem. Has anyone else come across this or is there a workaround?
Many thanks if anyone has any insights.
Peter

Yeah, I don't know why the difference. Interestingly for me, the iOS version in iOS4.2 is "better" than the OSX version of Mail because now I can have more than one Exchange account.
I am sympathetic with your need to separate your lives. I have a client that accidentally got one of my alternate email addresses and cannot/will not update his address book with the "correct" address, despite my requesting several times over the course of a year. In any case, I don't think there is any way around this other than completely changing your email address. (If not a second Gmail, then Yahoo, Hotmail or other email provider.)
The only time I've ever seen a "no password" SMTP server was as I previously said, it used a "network authentication" method. Many, many moons ago, SMTP servers often didn't have password authentication so would often be used for spam relaying. Before mobile users, "network authentication" by ISPs was fine since they could figure out which user was spamming since they could trace the IP addr, MAC addr, etc back through the physical link to the user. But with mobile users who change networks constantly, the general trend was to password authentication, even for wired ISPs since their users would want to have access to send mail while away from home. (e.g.: you're a RoadRunner customer, but want to send mail while using your laptop on vacation in Italy.) This "prior authenticated download" I've never heard of anyone else doing.

Client can not connect to Server installed window server 2008 and using 8.8

HI all!
I have a problem when Client log in to server that installed window server 2008.It can not connect to this server even when restart and key in IP or Server name,...
I try disable Firewall of window 2008 in server machine and client can connect to server. But when i disable firewall, it's mean i can not use Remote desktop or terminal service..
Now, how i can do in order to solve this problem.
Thanks!

Hi,
Take a look at the admin guide (Page 75, 119, 159):
[http://service.sap.com/~sapidb/011000358700000150922010E.zip]
If you installed a firewall on the license service computer, make sure that the firewall is not set to port 30000; otherwise, the license service cannot work.
If you are using Port X, make sure that you open Port X and Port (X+1) in the firewall. For example, if you are using port 10000, make sure to also open port 10001.
The default communication port is 1143.
The default port of the SAP Business One license server is 30000 for license communication and 30001 for the license naming service

Can I install Windows Server 2008 R2 using Bootcamp? I do not want to install native, but may consider if that is the only way....

I already have Win 7 on an internal Bootcamp drive. It so far has worked well, Bootcamp performance drag is minimal, if at all. Now I want to install Win Server 2008 R2 and load a bunch of virtuals using Hyper-V Manager. The virtuals are already created. This is to practice for a certification test....
Running Mountain Lion, 2010 MP 2 X 2.4 (8 core) 24 GB RAM, all HDD slots full.

Works like a charm. Apple Supports says you can have multiple instances of Bootcamp. Win Server 2008 R2 is up and running, drivers installed (except issues with Bluetooth) and accepting Windows Updates and Service Packs.

SChannel Fails Authentication on Windows Server 2008 R2 Using TLS1

I am trying to use SChannel to secure a socket connection. I modified the example at
https://msdn.microsoft.com/en-us/library/windows/desktop/aa380537(v=vs.85).aspx, converting it from Negotiate to SChannel. Following the specs for the SSPI APIs I was able the get a Client & Server connection authenticated on Windows 7.
However, when I try running the same programs on Windows Server 2008 R2, either the Client side or Server side fails, depending on how I select the security protocol.

My initial attempt built an SCHANNEL_CRED structure following the documentation to set
grbitEnabledProtocols to 0, and let SChannel select the protocol. This worked on Windows 7, selecting TLS1. When I ran the same exe-s on 2008 R2, the Client program failed, with InitializeSecurityContext returning SEC_E_DECRYPT_FAILURE.
The failure occurred on the 2nd call, using phNewContext returned on the first call.
My next attempt set grbitEnabledProtocols to SP_PROT_TLS1_SERVER. This also worked on Win 7, but 2008R2 failed again, this time on the Server side. AcceptSecurityContext failed, returning SEC_E_ALGORITHM_MISMATCH.
TLS is a requirement for my project, but to try getting the sample to run, I next set grbitEnabledProtocols to SP_PROT_SSL2_SERVER. This did work for 2008R2, selecting SSL2, but now the Server failed on Win7 with AcceptSecurityContext returning
SEC_E_ALGORITHM_MISMATCH.
My final try was to set grbitEnabledProtocols to SP_PROT_TLS1_SERVER | SP_PROT_SSL2_SERVER, but that failed identically to the first case, with the Client on 2008R2 returning SEC_E_DECRYPT_FAILURE.
So my question is - What is required to get SChannel to select TLS regardless of the Windows version on which the programs are running?

Thank you for the reference. That did provide the information I needed to get TLS working. However, the documentation is not accurate with regard to setting the registry keys and values.
The tables all show DisabledByDefault as a subkey under the protocol. They also describe a DWORD value, Enabled, as the mechanism to enable/disable a protocol.
What I found is DisabledByDefault is a DWORD value under Client/Server and it appears to be the determining factor to whether a protocol is enabled/disabled.
The only way I was able to get TLS 1.1 working is with the following path present:
HKLM SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client
Under Client, I must have DisabledByDefault set to 0. With that, the Enabled value does not need to be present.
This held true for any level of TLS.
I also found the setting of grbitEnabledProtocols in the SCHANNEL_CRED structure to be misleading. From the description at
https://msdn.microsoft.com/en-us/library/windows/desktop/aa379810(v=vs.85).aspx, I thought my Server program could set this field to 0, and SChannel would select the protocol as directed by the registry. What I found is that the structure flag must
agree with the registry setting for TLS to work. That is with the resgistry key above for TLS 1.1, I must set grbitEnabledProtocols to SP_PROT_TLS1_1.
Can you confirm the relationship between the SCHANNEL_CRED contents and registry state?

Respooled emails do not use TLS

We have configured CF 9 Standard to use our smtp server on port 587 with tls. When new messages are created, we can clearly see the messages being sent successfully using TLS via wireshark.
However, when a message fails to send and gets put in the undelivered folder and we try to respool it, it does not try to use TLS again and since it doesn't never can be resent.
How can we get messages that are respooled to use TLS?

HI Mack,
The mail in the undelivered folder that gets respooled, is pointing to the exact same server configured in CF Administrator. However, it never start TLS when we respool it. I would expect to see something else in the server: or server-usetls or something since all the other information is in there, but it isn't.

Windows Storage Server 2008 R2 Using 4TB hard disk

Hi, I have a HP X1600 G2, then I bought 12 x 4TB hard disk for increasing the disk space for this unit.
What I want to do is using the hardware array to configure the following:
3 x 4TB RAID-5 plus 1 Spare to create 3 Logical Drives.
Then Spanned set it to a total of 24TB drive within the system.
Is it going to be work, or not?
As I read the article
http://technet.microsoft.com/en-us/library/cc773268(v=ws.10).aspx
Said to use 2TB drive to be able to get a 64TB in total.
Thanks in advance, Fortuno

Thanks Shaon,
Yes, after I setup on the RAID controller, with GPT on the hard disk, I am able to create the spanned set for 24TB on the Windows Storage Server 2008 R2 that comes with the unit.
Thanks again!

MS SQL Server 2008 not getting installed properly - MOF compiler could not connect with the WMI server

I am trying to install SQL Server 2008 in my local machine. However, I kept running into errors with the following error message:
"The MOF Compiler could not connect with the WMI Server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such
as the failure of the WMI Server to start".
I also ran "rundll32 wbemupgd, UpgradeRepository" to rebuild WMI repository, it doesn't help either. I got the same error message.
Any ideas what settings I need to change in order to ensure a successful installation of SQL Server 2008?

can you check below two links.Make sure previous failed installation is removed completely.
http://connect.microsoft.com/SQLServer/feedback/details/356258/the-mof-compiler-could-not-connect-with-the-wmi-server#
Solution given by Connect MS is:
Possibly the issue was caused by uninstalling from add-remove programs - at any rate, using aaron bertrand's suggestion below fixed the issue. Also of note - I used the local admin for the install.
http://sqlblog.com/blogs/aaron_bertrand/archive/2009/02/20/the-xp-sp3-msxml6-sp2-sql-server-debacle.aspx
yes - remove msxml6 and any other half installed portion of sql 2008 and REBOOT and install sql
