Recommded DAG for 4 site Exchange Org

Hi,
I'm with client that has 4 Exchange/AD sites: Virgiinia, California, UK and Germany.
All sites are well connected. Each Database has 3 copies total (CA and VA sharing copies, UK and Germany sharing copies). What would be the best solution in this scenario to have one DAG or 2 DAGS (one for europe and one for America)? Please factor in the
scenario where the link between Europe and North America goes down even though there are no databases being share between the two continents.

Hi,
I recommend pay attention to below link about Database availability groups and Exchange 2010 Tested Solutions with two sites(especially, steps 8 in Determine High Availability Strategy section):
https://technet.microsoft.com/en-us/library/dd979799(v=exchg.150).aspx

Deploy Exchange 2013 Edge Transport Server for multi-site environment

Hi,
I have a multi-site Exchange 2013 environment. The configurations are as below.
Active Directory Sites and Exchange Servers.
SiteA - EXMB1 & EXCAS1
SiteB - EXMB2 & EXCAS2
SiteC - EXMB3 & EXCAS3
All sites are connected via VPN. (Good speed. No latency issues)
All the three Mailbox Servers are in DAG. Only one mailbox database. All servers running Exchange 2013.
I am planning to deploy Edge Servers in the infrastructure (I am doing it for the first time). Normally, it will be in DMZ.
Now, I can deploy 2 Edge Servers for reliability.
Question.
1. Can I deploy 2 Edge Servers and create subscription to all the mailbox server in 3 different site? Or, is it like one edge server can make subscription to only mailbox servers in one Active Directory Site? I am not sure about this and could not find much
information from TechNet.
One Edge Server can make subscription to all 3 mailbox server in 3 sites. Similarly, I can make the subscriptions in the second edge server as well. Configure 2 external MX records with the same priority so that there will be some load balancing.
Also, in such a case if the mailbox database become active from a different site, I need not make any new changes to the Edge Servers right?
2. If the first way is not correct, I will have to deploy 1 Edge Server each for each of the Active Directory Site. (In DMZ only, not in domain)
Make Edge Subscription to the mailbox server in corresponding site.
Make 1 MX record and point it to the Edge Server which is subscribed to the Mailbox Server from which the Database is Active. The problem is, every time will have to change the DNS record when ever the database copy is activated from a different mailbox
server. And the issues with propagation.. delay..
I am not sure which of the above 2 ways will work. Appreciate suggestions from anyone who have previous experience with similar infrastructure.
Thanks in advance. :)

Hi
One or more Edge Transport servers can be subscribed to a single Active Directory site. However, an Edge Transport server can't be subscribed to more than one Active Directory site. If you have more than one Edge Transport server deployed, each server can be
subscribed to a different Active Directory site. Each Edge Transport server requires an individual Edge Subscription.
A subscribed Edge Transport server is associated with a particular Active Directory site. If more than one Mailbox server exists in the site, any of them can replicate data to the subscribed Edge Transport servers.
I don't think there is a solution to subscribe edge servers for more than 1 site. Edge Servers can be scoped only to one site.

Error 1006 - Changing Ad Site for subnet where exchange 2013 servers was setup

We wanted to change Ad site for subnet where exchange 2013 servers was setup.
When we do that error id 1006 appear on 2 MBX Servers :
The Microsoft Exchange Mailbox Replication service was unable to process jobs in a mailbox database.
Database: Database02
Error: An attempt to logon cross-site for Mdb 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' was prevented to Server 'yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy' in Site 'DomainAAA/Configuration/Sites/SiteB'. Local site is 'DomainAAA/Configuration/Sites/SiteA'.
DomainAAA - Our Domain
SiteA - AD site which temporarily cover subnet A and Subnet B
In subnet A are installed 2 DCs (Global Catalog) and other aplication servers.
In subnet B are installed all EX2013 servers (2 MBX and 2x CAS) ,1 DC (Global Catalog) and other app servers.
SiteB - new created AD site intended for subnet B
These subnets are on diferent physical location.
When we change Ad site for subnetB from the AD siteA to AD SiteB, above error appear.
There is a object ExchEdgeSyncService under the AD site : SiteA , where the installation EX2013 was done.
So do We need to create the new edgesyncservice under the siteB ?
What steps do we have to make ?
Our intention is to eventually remove all servers from the siteA and move to to SiteB.
So that siteA will no longer exist.
Thanks in advance , and sorry for bad english.
Best regards

Hi,
Why don't you just extend the VLAN so you don't have to create another site and do changes so much

Urgent Help / suggestion Needed - DAG in Differnt Site - Implementaion

Hi All
Current setup of my lab is below -
MAIN SITE - Named Head Office
Root Domain Controller : IP 172.29.154.1 / 255.255.0.0
Two node DAG : - Mailbox servers - DAG NAME - DAG1
Casarray (casaarray1 , and casarray2) servers
One hub transport server
Total 6 VM servers are running in the head office site
Created a new AD site for name Branch Office and installed a addition domain controller with IP of 10.10.10.1/255.0.0.0
Now i would like to implement the DAG between the sites .
how can i implement, i mean what are the best ways to implement the DAG between two sites
1. shall i go for typical installation of exchange (CAS, HUB , MAILBOX ) 2010 in main office and Branch office . will it support DAG between two sites for typical installation?
2. shall i install one more Mailbox server alone in MAIN SITE and install CAS and hub in one server and mailbox alone in the branch office site? i mean - two Mailbox servers in each site
any other best ways other than above two points , the main intention is to implementing, testing and learning the site resilience between the sites and want to know the stuffs in and around DAC
Thanks in advance

so, i was assuming that i will add one mbx server in main site and another mbx server in branch site and make it HA via DAG --- is it possible
Next option
i can go for typical installation of ( CAS , HUB MBX server (all three in in one server) in main site and another three server roles (aal in one server) of Branch office and make the mailbox for HA -- will it possible
how can i achieve the HA with my current setup between the sites
If your bandwidth and latency between sites  you
can have  HA for mailbox databases by adding a mailbox server as a member in the current DAG. DAG will
give you only HA for mailbox not HUB/CAS.
After you installed the Mailbox role on the branch server, You have to set autodiscover site affinity.
http://technet.microsoft.com/en-us/library/aa998575(v=exchg.141).aspx
It is little bit complicated if you want HA over 2 sites, It depends on the bandwidth and latency between sites. If
you install all the 3 roles and configure the branch site as part of the main branch ADsite you can have highly availability for CAS by a load balancer and this is not a small change. i.e. add the branch server to the Main office CAS
Array and load balance.
http://channel9.msdn.com/Events/TechEd/NorthAmerica/2011/EXL401
If the branch site is not Internet facing, Please check this.
http://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx
adding an MBX/HUB/CAS in your branch office and buy a hardware load balancer of your budget. List
of MS supported HLBs here.  Configure the load balancer to according to your bandwidth and latency
between sites.
Thanks, MAS

Couple of comments please!
Autodiscover sitescope is a function of CAS not mailbox. This is written into AD when the CAS role is installed.
Why are you splitting all the roles out like this? The recommendation in 2010 and 2013 is to multirole whenever possible. There are valid reasons for splitting, I just want to know what's driving you to this.
The preferred DC switch is just for the current PowerShell session IIRC. I'll check up on that though.
I'd ask you to look at the design examples on TechNet
http://technet.microsoft.com/en-us/library/dd979781(v=exchg.141).aspx
In all of this, you have to consider what the impact of a failed WAN link(s) will do. If you have a single DAG spanning both locations, and the WAN goes down then in the case of a single DAG spanned between both of the sites some users will not have
access to a local mailbox server. The cluster service terminates and so does the Exchange store. That is by design.

The passwords and usernames i have for my sites got erased, how can i get them back or reset them so when i open them they nolonger ask me por that info like gmail

Firefox deleted all of my saved usernames and passwords for the sites i allowed them, For instance I can no longer click gmail and be at my e-mail and see my email, but i am promoted for password and username.

''passwords and usernames i have for my sites got erased''
Did you have them after updating Firefox, or did you lose your passwords as well. If you lost everything you either created a new profile and are in it, or you accidentally/intentionally cleared your history (see picture link). If you cleared your history, the changes are permanent and they are gone.
If you cleared your history, except for bookmarks in backups, you will have to try for
#Data in an older profile, for most people this would only be if one accidentally created a new profile, such as during a Firefox installation.
#Your own backups
#Old password, cookies from Internet Explorer
Use the "Alt" key to temporarily see your toolbars. Use the view menu to display any toolbars that should be displayed, such as the Bookmarks Toolbar.
Check these:
*Do you have bookmarks Ctrl+B (Bookmarks sidebar), if you don't see your own bookmarks but you see those from when you first installed Firefox, you are probably in a new profile, using the Profile Manager could bring up another profile.
*Check your current bookmarkbackups for dates
:On current profile, you can check dates, and restore/replace current bookmarks from a backup. "Ctrl+Shift+B" to bring up the Library List, then in the "Import and Backup" menu, choose Restore to see what dates are available. This will tell you the last 11 dates you used your current profile in Fx5 (5 days if Fx3). You can restore if your bookmarks are messed up.
Profile: ''Find out if there are multiple profiles''
:type in '''about:support''' into the location bar :Click on "Open containing folder" :You are now in your current profile :go up one directory level to "'''Profiles'''", where you can see if you have more than one profile directory :files of interest (check last used/update dates) within profile: places.sqlite file, and within bookmarkbackups folder are .json bookmark backups for dates.
'''Deleting History/Lost History''' (Tools -> options -> Privacy), make sure you are not clearing in "Settings for Clearing History" anything but cache. The items you have check-marked there will be cleared at end of session if "Clear history when Firefox closes" is check-marked. If under tools you click on "Clear recent history Ctrl+Shift+Del" you should be asked for how much history to delete {1hr, 2hr, 4hr, today, everything} and what to clear in the details drop-down. Make sure when using the location bar you are displaying both "History and Bookmarks" so the AwesomeBar can look for items from both.
* http://img232.imageshack.us/img232/4928/clearcachew.png
'''You should be backing your for Firefox profiles''', there is not a lot of data and you should be backing up frequently. The is a lot more data for other applications in you Windows user library and you should be backing up data from there as well.
When you backup all of your user data to external hard-drive (500GB to 3TB) your Firefox profiles would be included.
But this is about Firefox. For Firefox a thumb drive would probably suffice to backup one or more profiles.
'''backing up your Firefox Profiles''' (the following is all on one line)
xcopy C:\Users\''<username>''\AppData\Roaming\Mozilla\Firefox\Profiles\*.* g:\profiles\*.* /s /d /h /y /c /q

In Security, clicking on the "Saved Password" button displays your current saved password for each site. It does not allow you to change a password. How would you do that?

In Security, clicking on the "Saved Password" button displays your current saved password for each site. It only allows you to view and delete site passwords. It does not allow you to change a password. How would you do that?

If you enter a new password Firefox should offer to change the password.
*You may not need to delete the old password. Try "Refreshing" the page, entering the site again, you may need to let Firefox fill in the old password, then enter the new password, and Firefox should ask to save the new password. See:

How to disable PDF.js built in viewer for my site

On my site PDF files are used for printing purposes. Starting with v19 visitors start start to claim that this functionality is not working any more. The cause of this is the new built in PDF viewer. It doesn't open print dialog after pdf file download if the the file is built to doing this. Also I’ve found that the quality of printing via the built in viewer is unacceptable. The content is distorted by the JPEG compression and additional headers and footers are present on the page. So for my site built in PDF viewer should be disabled at all. I've found no way to do this at the site level. I think that the instructions for disabling the new feature is too complex for ordinary users and it easier to ask them to use another browser.
I think that should be an option at the site level to disable the built in PDF viewer. At least this option should force the browser to ask the user that for working properly with this site the built in PDF viewer should be disabled. And if user choose to disable it this should be done in one click.

@john99,
FF19 ignores your "Application preferences", described in [[https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file]]
and
[[https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-without-downloading-them]]
as long as pdf.js is enabled. This is counter-intuitive and user-unfriendly. One shouldn't have to override settings (disable pdf.js) in about:config for an option configurable in the regular GUI to work as expected.

How do I save password info for a site when Firefox does not offer to?

Certain sites that require a password I do not remember ever being offered the opportunity to save a password for that site, so it doesn't show up in rejected, and I can find no option to get Firefox to offer to save password info for me...aside from this I have been very pleased with Firefox since i made the switch in Sept...Thank you, a technically challenged grandmother...

If a website doesn't offer to store the password then chances are that it doesn't fill that password either if you use the "Saved Passwords Editor" extension. You can only use that extension in such a case as a reminder in case you forget the password.

Complex string pattern match/sort question for mapping data - Exchange Enable mailbox use case

Hi, Im trying to do a runbook to Enable mailbox for a user. Our Exchange Admin uses a rule/formula to allocate the mailbox database based on users first name and this is what I am having difficulty replicating in Orchestrator to add the correct
data in the Database property of Enable Mailbox activity.
The Rule exchange uses, takes up to the first 3 chars of forename and based on an alphabetic sort, it will allocate to a particular mailbox db (we have a quite large Exchange Org with 20k users so hes tried to allocate about 500 users per mailboxDB). so
for example User Forename A-ALI = DB1, ALL-ANG = DB2, ANH-ANY=DB3,AO-BER=DB4 etc etc.
So I was hoping someone could advise of some string comparison activities native in Orchestrator or maybe done as last resort in powershell (as I'm not great in powershell) to provide a map of the published data for forname to appropriate mailbox matrix.
Any help on this would be much appreciated...
Cheers

You could use the built in Mid function [Mid(‘Return subset from this string’,1,3)] to get the first three letters of their name and honestly I would send
this to the Run .Net Script activity using powershell myself and do a select case to get it to publish to the database the name of the database server.
I am all for using built in activities to do things in Orchestrator but you are going to quickly find that you need to have good powershell scripting skills to extend the tools beyond the capabilities of the built in activities.

Want to reset the stored ID/Password for a site

I need to reset the stored ID/Password for a site. I entered the wrong ID and clicked Save on the pop-up for saving password for the site. Turns out I used the wrong ID to login and now I can't reset it to the correct spelling. It keeps overriding what I type in.

How do I save my user name a password for a site that doesn't automatically ask me if I wish to?

Normally Firefox will ask if I wish to save the user name and password for the site I've just logged into. This time it did not ask me this. Is there somewhere that I can add this information so I don't have to remember it for when I come back in a year from now and am trying to log on again? I went to tools>internet options>security>passwords but nothing there seemed relevant.

Some sites block passwords from being saved. For more details and how to bypass this see http://kb.mozillazine.org/User_name_and_password_not_remembered

How do I save passwords when I initialy told it "never for this site"?

I have several sites that I want to save the password for, but when the prompt first showed up I clicked on "never for this site" and now I want to change to remember but the prompt doesn't show up and I don't know where to find it.

Remove the site from the exceptions: Tools > Options > Security: Passwords: Exceptions

How to block javascript for custom sites?

Sometimes I need to disallow javascript for some sites only. I can do this in Opera. Is this posible in FireFox?
For example, I don't like the javascript at google.com when I'm searching for images because the images (thumbnails) are increasing size on mouse over. Can I disable javascript for google.com only?

There is not a built-in way of doing this, but you can add that capability by using the [https://addons.mozilla.org/firefox/addon/4922/ YesScript] add-on.
