How to configure Exchange 2010 to use a certain MX record that is unavailable with public DNS
Dear all,
as for TLS encryption I'm required to send emails destined for a certain domain via a dedicated send connector that has TLS encryption enabled/enforced. Thing is that the recipient's corresponding domain MX records cannot be resolved using public DNS. As soon
as I verify MX records for the recipient's domain using nslookup I only receive MX records that do not accept TLS. In order for TLS to work I'm required to send all outgoing emails to that specific domain via a certain predefined host, i.e. MX record, that
is known to me and Exchange needs to know as well. But how can I configure Exchange to use a certain MX record (that resolves to mxtls.<domain>.com instead of mx.<domain>.com without being available in public DNS?
Editing the hosts file directly on the Exchange server? Not an option, right?
Messing with my ADS integrated DNS not an option, too, as I then have to add all sorts of entries for that zone, e.g. www and stuff like that, to make it work?
I'm lost here, any help would be greatly appreciated.

Well, I figured it out by myself. I just had to add the corresponding server, i.e. mxtls.<domain>.com, to the Smarthost configuration for the corresponding Send Connector and set its RequireTLS setting to $True.

How to get Exchange 2010 Product Keys from an existing installed servers
hi All,
we are facing some kind of critical issues. we had 3 MB servers . the two servers are in DAG all our productions DB's running in DAG. the DAG servers are crashed due to hardware issues. one server is acting as archival server. all servers are running exchange
2010 sp3.
now we are trying to rebuild new servers to restore DB's. the new servers is prompting the product key to be entered. unfortunately we don't have product keys of exchange 2010. since we are gold partner we have partner network portal. when i tried to get
the product key from portal am able to see only 2013 keys. we called up Microsoft and explained but no use. they said we have to use exchange 2013. but we cant simply go ahead and migrate.
but the only option is we have exchange 2010 installed servers they all act as CAS/HUB server with the same licence. please let me know how do i retrieve exchange 2010 product keys from an existing servers. Please advise me its very critical.
can we get the product keys through some kind of scripts?
Thanks, Venkatesh. "Hardwork Never Fails"Hi,

How to get Exchange 2010 database size c#
I'm trying to get smallest Exchange database in my Exchange 2010 server using remote session.
I successfully connect to my exchange server and get database with properties. Some of them with value, but Properties "DatabaseSize" with Null value for each of them.
Did some body be able to get database size value?
For me important to use URI to connect Exchange DAG.
Part of my code below:
static void Main(string[] args)
string exchangePowershellRPSURI = "http://my.domain/powershell?serializationLevel=Full";
PSCredential credentials = (PSCredential)null;
//Provides the connection information that is needed to connect to a remote runspace
// Prepare the connection
WSManConnectionInfo connInfo = new WSManConnectionInfo((new Uri(exchangePowershellRPSURI)),
"http://schemas.microsoft.com/powershell/Microsoft.Exchange", credentials);
connInfo.AuthenticationMechanism = AuthenticationMechanism.Kerberos;
connInfo.SkipCACheck = true;
connInfo.SkipCNCheck = true;
connInfo.SkipRevocationCheck = true;
// Create the runspace where the command will be executed
Runspace runspace = RunspaceFactory.CreateRunspace(connInfo);
// Add the command to the runspace's pipeline
runspace.Open();
//Represents the base functionality of a pipeline that can be used to invoke commands
Pipeline pipeline = runspace.CreatePipeline();
Command getMDB = new Command("Get-MailboxDatabase");
getMDB.Parameters.Add("Identity", "*");
getMDB.Parameters.Add("Status", null);
pipeline.Commands.Add(getMDB);
Collection<PSObject> select = pipeline.Invoke();
if (select.Count > 0)
foreach(PSObject obj in select)
var db = obj.Properties["DatabaseSize"].Value;
string name = obj.Properties["Name"].Value.ToString();
Console.WriteLine("Database Name: {0} Size: {1}", name, db);
else
Console.WriteLine("Failed to create email account");
runspace.Dispose();
Console.ReadLine();I found solution of my problem by myself. I just changed in string
getMDB.Parameters.Add("Status", null);
"null" to "true" like this:
getMDB.Parameters.Add("Status", true);
Now everything work fine for me. -
How I can set Leopard to use the color management mixture that Tiger uses?
I have recently bought a new Mac with Leopard installed. My old Mac is running Tiger. Unfortunately the color management default settings in Leopard are different than in Tiger, so this is completely messing up my calibration. Can somebody please tell me how I can set Leopard to use whatever color management mixture that Tiger uses? - Thanks.
I already have set FF to No Proxy. This made FF work again, but not any of my other internet programs, programs that don't have the option to set to no proxy, they rely on the system settings. So I need to know how to reset my system settings back to their default values. This will allow all my net progs to access the net again, including FF using the Use System Settings option. Since FF has an option to use system settings, this is a somewhat FF related question. I need to get all my net programs working again, not just FF! And, if my system settings are restored, FF will work using the system settings, and all my other progs will work too.

the feature you are trying to use on a network resource that is unavailable. i cannot find Quick Time.msi file anywhere. so i cannot uninstall or re install quick time
any suggestions please??????Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove".
Quit out of CleanUp, restart the PC and try installing QuickTime again. Does the install go through properly now?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.) -

I get a error message "To charge faster, use the cable and device that were provided with this phone" when charging my Samsung Galaxy note 3. I took it to a store last week and they said it has something to do with the last software update. They tried charging it at the store and got the same message. I was given another phone, I still get the same error with the new phone.
Wowuor,
Thank you so much for reaching to us today. I want to make sure that we get the device charging the correct way. There is no physical or liquid damage to the phone or to the power cord correct? Did this error just start to appear as of last week? Please keep us posted.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

Yo des intale itunes en mi laptop. Tiempo despues instale el ultimo itunes alli mismo. Cuando quiero darle el setup, aparece: The feature you are trying to use is on a network that is unavailable, y: The older version of itunes cannot be removed. Help!
The feature you are trying to use is on a network resource that is unavailable
I give it ok, I get same msg.
I give it cancel, then: The older version of ITunes cannot be removed. Please contact your tech support group.
Please help I need this ..(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time? -

Hello teachermama10, The Factory Data Reset does remove all data including files and photos. I understand that making sure your phone information is backed up is of the upmost importance. You can ensure your phone data is backed up using these links: http://vz.to/1uM5mwZ and http://vz.to/1vEzYok. You can also try our great Verizon Cloud feature as an option for backing up and syncing your phone info! Check it out: http://vz.to/1s4GctA.

Hi all,
need urgent assistance on the following issue
this is my Exchange 2010 setup
2 x CAS/Hub servers with HP network teaming, and load balanced using Windows NLB multicast mode. There are 2 VIPs on the NLB, one for outlook anywhere, one for autodiscover
2 DNS records were created for the 2 VIPs
Clients use Outlook Anywhere (HTTPS) to connect to the CAS servers from external segment via a Palo Alto firewall, which also acts as a layer 3 router
static arp was set on the Palo Alto firewall, with both virtual MACs pointing to the primary virtual MAC used by the NLB.
Observations
1. within same segment - no issue accessing Exchange servers, even when one CAS node is offline
2. external segment (via firewall)
a. when both nodes are up
outlook client able to connect to Exchange CAS VIP on 443, but will disconnect after around 30 seconds. Client will retry and the pattern will repeat
Exchange CAS RPC logs shows client connections and disconnections to the outlook anywhere VIP address
Firewall logs shows allowed traffic from client to the VIPs
unable to complete profile creation
b. with only CAS2 (CAS1 stopped/deleted from NLB cluster)
no issues accessing Exchange servers, creating profiles etc
c. with only CAS1
same behaviour as (a)
reinstalled NLB, but doesn't resolve
deleted CAS1 from NLB cluster, and re-add. issue remain
Q1. is teaming supported? Teaming is currently set to automatic mode, instead of specified Fault Tolerant
Q2. are there additional settings we need to set or verify on the Palo Alto firewall, since the issue only happen to external segment? Thanks!Yes - I've been scarred with this for many years :(
If it is just CAS 1 that is causing issues, then focus in on that. The support statement for Win 2008 R2 is that NLB is still a 3rd party component and support may ask for it to be disabled.
http://support.microsoft.com/kb/278431
Does CAS1 and CAS2 have the same NICs (firmware as well), driver, teaming software, and teaming config?
I also want to ask what the network team did for configuring the switch ports on the servers? This will vary from vendor to vendor - did they do the same config on both?
Cheers,
