Exchange 2013 mailflow and the Hosts file

Hello!
Recently I expirienced the issue with missing messages ( http://social.technet.microsoft.com/Forums/en-US/20745ec5-e311-4bc0-b1bd-aff3f7c82fd1/missing-messages?forum=exchangesvradmin ) and although that thread is not answered yet I would like
to clarify the following:
1) Exchange Server is working properly for day1 and day2
2) Day3: Sent messages begin to disappear
Resolution: I add my Exchange Server to the hosts file (on the Exchange Server machine), restarted the server and the mailflow was restored.
192.168.1.2 Mail
192.168.1.2 Mail.Test.Local
Test: Right after deleting Exchange Server records from Hosts and restarting the server the mailflow gets disrupted again.
Q1: Is it a bug?
Q2: If it's a bug why my Exchange has been working fine for day1 and day2?
Thank you in advance,
Michael

Hello all!
Here's my post that describes the issue:
http://social.technet.microsoft.com/Forums/exchange/en-US/20745ec5-e311-4bc0-b1bd-aff3f7c82fd1/missing-messages?forum=exchangesvradmin
There're two servers (VMs): Domain Controller and Exchange 2013. As I have no internet connection in my test environment only internal mail go missing.
Regarding Hosts file: as those post is still not answered I just did what MS support recomended for resolving Exchange 2013 DNS issue (there're a lot of posts regarding it here on technet) and it helped...
But it's nonsense - my DNS is up and running, it was running on Day1, Day2 and Exchange could use it successully, but starting with the Day3 Exchange Server can't use the same DNS server? Why???
Regards,
Michael

We have a Exchange 2013 server and the Mailbox Database folder is filling up with .log files.

We are migrating from Exchange 2010 to Exchange 2013. We have installed the Exchange 2013 but it only has a couple of mailboxes on this server, all the mailboxes are still on the Exchange 2010 server.
I have run a Windows Backup of the Exchange 2013 but I am still seeing a ton a log files in the mailbox folder.
Also the database file is only about 1.1 GB but the backup is now 40 GB.
Is there something that can be done to truncate these logs and make the backup smaller?

Hi ,
1.Does the full backup completed successfully ?
2.what about the status for the below mentioned command ? Does the mailbox database headers updated with the latest time and date ?
Get-MailboxDatabase -Status | ft name,*full* -au
3.Just check the application event logs for the event id
2046 and that should state that the log truncation for the mailbox databases has been initiated or not.
4.Before initiating the backup just make the exchange writer is not on error.
vssadmin list writers
In case if it on error state ,please restart the Microsoft exchange replication service and check the exchange writers status again by using the above mentioned command.
Thanks & Regards S.Nithyanandham

What is the real ip address to the apple server? Someone changed the host file in windows/system32/drivers/ect, and now I can't do a restore on my iPhone 3gs.

"You have to change your router's IP address to be able to access it. It will not give you the internet."
I'm not sure what that means Richard, but I did change the router's IP address from 192.168.1.1 to 192.168.5.1- isn't that what you meant in your first post. I know that isn't reflected in my screen capture that I took last night, but I did do that this morning after I read your post.
"Log on to your router and change two settings.
Change the setting in Setup from PPPoE to Automatic Configuration-DHCP and click on save.
Click on Advance Routing and change the setting from Gateway to Router then click on save."
I did this and still same results as far as I can tell. Can't get online through the router.
"Click on MAC address clone under setup tab ... click enable & click clone ...click save settings ... Check the IPaddress under WAN page ....
If getting IP in public range .... try going online ...."
I tried this- at least to the part about checking the IP address under WAN. I assume you mean the WAN page in the modem setup- nothing looked any different after trying what you suggested, and I'm not really sure where I would be "getting IP in public range" or what that means.
I'm about to give up and just buy a new router to see if I can get the same lack of results with a different one. My ISP maintains that everything is set up correctly on their end and really can't do anything more for me. The Modem works and is set up correctly and they can give tech support for a router.
Here's what my basic setup looks like now:

Double prompts for Exchange 2013 migrated users: "The microsoft exchange administrator has made a change that requires you to restart outlook"

I have Exchange 2010 SP3 in my environment and am migrating to Exchange 2013. Whenever a mailbox is migrated, the Outlook 2013 client will prompt the user with a "the exchange administrator has made a change that requires you to restart
Outlook". When the user does so, he or she is prompted again. After he or she closes and reopens Outlook for the second time, the issue is gone permanently.
I've seen a number of other posts about repeated prompts like this but I haven't yet found one or someone gets exactly 2 prompts for each client and no more.
A couple of pieces of information that may be relevant:
1. On exchange 2013, the authentication method for the internal host name is NTLM
2. I have not yet migrated public folders from Exchange 2010. I plan to do that after the mailbox migration is complete.
Thanks in advance for your help.

Hi,
From your description, after mailboxes are moved from Exchange 2010 to Exchange 2013, users receive the following prompt when opening Outlook.
The Microsoft Exchange Administrator has made a change that requires you quit and restart Outlook.
In order to solve this issue, you need to apply the Outlook update that is described in KB 2863911.
For your reference:
Outlook 2013 cannot connect after an Exchange Server 2010 mailbox is moved to Exchange Server 2013

Exchange 2013 mailflow issues & transport latency

Hi,
we have more then 50 Exchange Server 2013 deployed and every single Exchange has transport issues.
-the transport Service do not respond for 30 min or more.
-RAM consumption
-the e-mail are stock in outlook for long time
-we have Exchaneg 2013 with all CUs / SP1 version installed and i cannot see any improvement.
I m disappointed and i hope that someone can help me to understand the Exchange 2013 Mailflow

Exchange 2013 SP1 and CUCM 9.1.2 - Exch not recognizing called extension

I think I'm almost there in getting Exchange 2013 SP1 UM working with CUCM 9.1.2...I've got two issues at the moment that I need a little help with.
1) When I dial my VM pilot (6040) from a UM enabled extension it prompts to enter an extension. When I dial the same extension and let it ring to VM, Exchange picks up and says "the person you are trying to reach does not have a valid voice mail box
on our system".
2) This just started happening this afternoon, when I dial my VM pilot (6040) exch3 picks up as thats what I have my route pattern pointing to. If I enter the extension of a mailbox on exch2, I get stuck in a endless loop.
I've followed this post as a guide but it hasn't resolved my issue.
https://supportforums.cisco.com/discussion/11914031/exchange-2013-um-and-cucm-86
My Exchange environment looks like this:
Site 1:
exch1 - CAS/Mailbox, used for mainly utility type work, journal, dedicated SMTP flows etc
exch2 - CAS/Mailbox, part DAG13
exch3 - CAS/Mailbox, part of DAG13
Site 2:
exch2dr - CAS/Mailbox, part of DAG13
exch3dr - CAS/Mailbox, part of DAG13
DAG13 is stretched between two sites, there are no users at our DR site so CUCM is pointing to Site 1 for UM. Each site has an internet facing CAS-only server for OWA/EAS etc.
Any help is greatly appreciated. I'd love to get rid of Unity.
EDIT:
I just found this event in the event logs:
The Microsoft Exchange Unified Messaging service on the Mailbox server received a diverted call with ID "d51600-3a3140c5-9b8-c1414ac@EXCH3-IPADDR" for extension "4099" on UM dial plan "CUCM" from UM IP gateway "CUCM IP",
but no UM-enabled mailbox for the corresponding extension could be found. Please check the extension and make sure that the corresponding mailbox is enabled for UM and associated with the correct UM dial plan.

9.1.2 I think it is, we upgraded to avoid the known DNS bug
I cant see how to PM you either
The crux of it was outlined below with some tweaks
http://blogs.technet.com/b/canitpro/archive/2014/04/30/step-by-step-integration-between-exchange-2013-um-and-cisco-unified-communication-manager.aspx
As we have multiple combined role servers, our trunks are set up as follows:
1. 1 x CAS Trunk - contains all CAS Servers on port 5060
2. 4 x MBX Trunks - contains Maibox Server with ports 5062-5068
On top of that, we had to Allow "Redirecting Diversion Header Delivery - Inbound (and Outbound)" on the CAS Trunk but DISABLE it on the Mailbox Trunks
Also, make sure that you are using Telephone Extension Dial plans in Exchange 2013 (Despite them being unable to be associated with a 13 Server - EX13 answers for all calls anyway)
Lastly, the MS documentation is a little strange - it says that as your last step of UM migration, you should point your Call Manager to 2013 - I don't agree with that statement, EX13 routes calls back to 2010 UM Servers perfectly fine, so treat it the same
as any other CAS based service - point to 2013, and it will handle the rest

Cannot get the hosts file to operate or change.

I have tried to every way I could find on the internet to change the hosts file on my Mac OS X 10.4.11 computer plus several newer macs that operate in my office. I was able to easily do it on the PC's but not on the Macs. I modified the /etc hosts file directly to no avail, modified it using the terminal commands and also tried using the NetInfo manager. I am NOT a tech guy, just a guy trying to get his computers to work properly. A tech company just changed our router to a Cisco ASA device which is why this change needs to be made, they did not know how to make the changes to the hosts files on a Mac. Everybody in the office loves our Macs so to not be able to get to our own website and webmail is frustrating. Here is what I changed the hosts file to:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
192.168.16.2 auctionbid.stoutauctions.com
192.168.16.3 mail.stoutauctions.com
192.168.16.3 smtp.stoutauctions.com
192.168.16.4 stoutauctions.com
255.255.255.255 broadcasthost
::1 localhost
Is something else in the system I need to change to make this take effect? Is something set wrong? Any help would be greatly appreciated.
Also if anyone knows of a reputable company that will do remote work on Macs, please let me know. I have a few things that I don't know how to do and would not be worth a trip to the middle of nowhere for a tech company so if they can do it remotely that would be great.
Thanks!
Greg

Hmmm, the line after...
127.0.0.1 localhost
Should be...
255.255.255.255 broadcasthost
Not sure if that is it or not.

How do I edit the hosts file in Lion

I tried to edit the hosts file in Lion with: sudo nano /private/etc/hosts. Then entered Password. The window came up blank evev though I know there is data there.

Thanks BD for your response. I have looked at Youtube where they are demonstrating how to do this by using sudo nano /etc/hosts. After entering the Password it shows a screen with the text of the hosts file. On the bottom of the screen it shows the number of lines read. When I do the same thing I get a blank screen and on the bottom it says no file. I am either doing something wrong or this does not work. I even tried changing the permissions of the hosts file to R & W for system, wheel, and everyone. This also did not work. I have not tried Hostal yet but if I can't find a simple way to text edit the hosts file I will give it a try.

Error 3194:
This device isn't eligible for the requested build
It means that Apple has stopped signing the version of iOS that you have, try downloading the latest iOS version, then try Restore again.

HT201210 I have done all of the things on this list, to include editing the hosts file with no the same error each time (3194). I am trying to restore my iphone 4 ios 6 to get it unlocked. Diagnostics show no issue communicating with apple. Help.

I am trying to restore my iphone 4 ios 6 to acheive unlock. hit restore and it unloads software, confirms with apple then displays the 3194 error. I have turned off my virus scanner, unplugged all usb except for iphone, edited the hosts file and run diagnostics which showes communication with apple is fine. What do I need to do to get my ipone to restore?

There is nothing wrong with the OS update.
Delete ALL your email accounts.
Restart Playbook
Put the accounts back and ensure they are all set with PUSH ON. Manual (push off) will burn battery.
Similarly delete your wifi connections and add back when required.
Turn off wifi is not connected to wifi.
Any "hunting for connection" in email or wifi will burn up battery.

Portal Access without configuring the Hosts file

Is possible to access the SAP Portal By mentioning the IP address in the URL without configuring the Hosts file?
Please suggest me.

Hallo Stars,
I am not able to understand the relation between the configuring DNS and affecting SAP installation. If you do not want to do the host file change or DNS configuration, i wonder how could your url request with Ip adress and port knows the physical server to reach.
Anyways it is going beyond Webdynpro-ABAP forum to the Networking,systems area. I request Moderators to replace this to appropriate forum.

Cross-forest migration to Exchange 2013 SP1 and Outlook 2013 SP1

Hello! I have two forest: Exchange 2010 SP2 RU5 - resource forest and Exchange 2013 SP1 - account forest. I make cross-forest migration from resource forest (linked mailboxes with account forest) to forest with Exchange 2013 SP1.
I have moved mailbox from resource forest exchange 2010 to exchange 2013 sp1 forest.
Outlook 2010 connect to migrated mailbox without any problem, but outlook 2013 sp1 cannot connect to migrated mailbox.
Error look like - cannot find exchange server.
I created new mailbox in Exchange 2013 organization and can connect to it with outlook 2010 and outlook 2013 sp1.
Someone have the same problem with migrated mailbox? How to solve it?
Truly, Valery Tyurin

You can use New-MoveRequest to perform a cross-forest move. Here is a well post and step-wise explanation you can check for cross forest migration from exchange 2010 to exchange 2013(http://msexchangeguru.com/2013/11/03/e2013crossforestmigration/).
Moreover, you can try this utility (

About the hosts file (syntax/usage question)

Hi,
I am trying to block a handful of different websites that I do not want my daughter to use right now. I would like to use the hosts file to do this. Although I have basic familiarity with the hosts file and editing it, I am not completely certain as to how it works and how DNS works. If I want to, for example, block "yahoo.com" and all of its subdomains, would the following be an acceptable/valid entry?
127.0.0.1 *.yahoo.com
By not listing the subdomains of "yahoo.com", would that make it any liklier for those webpages to get through? If I were to also list out all of the "yahoo.com" subdomains that I have knowledge of along with the previous entry, would that cause any problems?
And the second part of my question is: Is the hosts file ever not top priority in lookup (on OS X 10.6.8, if it matters); and if so, is there a good way to make it always first?
Any help would be appreciated!
Thank you,
Michael

Use parental controls, maybe Dnsmasq, or a nanny-capable firewall-gateway-router box that's been configured on the edge of your network.
The /etc/hosts file also has specific sequence to get it reloaded; that file is read once and subsequenty cached. IIRC, you need to either /sudo dscacheutil -flushcache/ or /sudo killall -HUP mDNSResponder/ the DNS resolver.
If your child is technically inclined, or knows how to do basic internet research, or has discussions with the more nerd-ish among her peers, your child can learn how to bypass /etc/hosts and Dnsmasq using her own DNS translations, or with her own DNS services. That possibility would point toward either parental controls (easy), or the firewall-gateway-router box (added cost, but can block some or all systems on your local network).
Here's how easy it is to bypass the /etc/hosts block; launch Terminal.app and issue the equivalent of:
dig +short @8.8.8.8 host.example.com
for the host.example.com host that you're (she's) interested in. (There are other commands that can be used; more than just dig can be used here, and there are web sites that can perform this translation for you.) Then connect to the IP address that this command emits. Your /etc/hosts block will not prevent this, and will not block this.
If your daughter is somewhat more technically savvy, a VPN will bypass the /etc/hosts blocks. She'll need access to a VPN server, and those are available from various free and very low-cost sources...

Hi,
you will need to config IM in OWA for Exchange 2013 server.As i can remember voice and everything else should be fine.
Here is a guide for enabling IM in OWA:
http://www.expta.com/2010/09/how-to-integrate-lync-server-2010-with.html
Just remember to point DNS to the New Exchange 2013 server and it should be fine.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you. Thank you! Off2work
