Can someone explain Exchange 2010 intersite message routing to me?

Greetings,
We are about remove our legacy routing group connectors and I want to ensure that I really understand how message routing in Exchange 2010 works. I understand that Exchange uses AD IP Site Links to determine best path unless an actual Exchange costs is assigned.
We have three sites A-B-C with Exchange resources. We have a DAG that spans sites and A and B. I have reviewed our AD IP site topology and noticed there is no direct IP site link between site and A and C. When a user is active in site A and emails a user
in site C, I would expect the message to be routed through site B first.
However, after reviewing the message logs i can see that the HT server in site A sends it directly to HT server in site C. So I guess i don't fully understand message routing. If there is no IP Site link between site A and C how and why does this work? No
Exchange Costs are assigned.
Thanks much!

Its transitive
http://technet.microsoft.com/en-us/library/aa998825(v=exchg.141).aspx
By default, all site links are transitive. This means that if Site A has a link to Site B, and Site B has a link to Site C, Site A is transitively linked to Site C. The transitive link between Site A and Site C is also known as a
site-link bridge.

  • Can someone explain what DHCP is and how I do I connect to WiFi  hotspot?

    Can someone explain how a wireless network/router with an internet connection allows computers with a wireless card to connect to the internet? For instance, In an internet cafe with WiFi, how does my macbook get the IP address for the ISP that the cafe uses to allow me to open a webpage with Safari? What is DHCP and how should I set my internet preferences to allow me to use a network other than my own.
    The reason I ask so many questions is that I can connect to the internet with my Airport Express base station network at home but not in my local WiFi cafe. Can see the network but not connect.

    Most Internet Cafes utilize DHCP to dynamically provide a wireless client with an IP address for that session. DHCP is a protocol used by networked computers (clients) to obtain IP addresses and other parameters such as the default gateway, subnet mask, and IP addresses of DNS servers from a DHCP server. It facilitates access to a network because these settings would otherwise have to be made manually for the client to participate in the network.
    You Mac's AirPort, in turn, is set up to be a DHCP client by default. This allows your Mac to accept the dynamically provided IP address information from the Internet Cafe's DHCP server.
    The reason I ask so many questions is that I can connect to the internet with my Airport Express base station network at home but not in my local WiFi cafe.
    It sounds like the AirPort settings that your Mac is using is no longer at their default settings...and my be the reason you cannot connect to the Internet at the Cafe...or, the Cafe has additional settings required. I suggest that you check with the Administrator of the particular Internet Cafe you're having trouble connecting with to find out what settings are necessary to use their wireless network.
    A typical AirPort is set up as follows:
    System Preferences > Network > Show > Network Port Configurations
    - Verify that AirPort is "On" (checked)
    - Verify that AirPort is at the top of the list. If it isn't, you can drag it to the top.
    Systems Preferences > Network > Show > AirPort
    AirPort tab
    - By default, join: Automatic
    TCP/IP tab
    - Configure IPv4: Using DHCP
    - Configure IPv6: Automatically or Off
    Proxies tab
    - Configure Proxies: Manually
    - Select a proxy server to configure: <All proxies should be unchecked unless you specifically require a proxy for Internet access.>
    - Exclude simple hostnames (unchecked)
    - Bypass proxy settings for these Hosts & Domains: <leave blank>
    - Use Passive FTP Mode (PASV) (checked)

  • Can someone explain the message about replacing songs when importing a CD?

    If this is somewhere, I have not been able to find the answer. When importing a CD, sometimes I get a message that asks if I want to replace existing songs. Can someone explain what this message means? I have tried replacing the songs and not replacing the songs, but I don't see any meaningful differences.
    Thanks!

    You should sort the list on the Album column, ideally as Album by Artist. Generally all you need to do after that is fill in an appropriate Album Artist. For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.

  • Can someone explain why the Secure Easy Setup light on a...

    Can someone explain why the Secure Easy Setup light on a WRT54G would change from a steady green to steady orange after firmware upgrade?  Everything is connecting properly, and I see no change in performance of network other than light change described.   Thanks. 

    The way I understand the Secure Easy Setup button is this.
    It will be orange when the router is in normal operation mode. The light turns green when you press the Cisco Systems button (that is orange normally) so that the router will search for the web device you are trying to connect to the router. If you want to disable this feature all together go into your router settings page at 192.168.1.1
    Go to the Wireless tab, and then the Advanced Wireless Settings sub-heading, once in there look for the option SecureEasysetup and simply set it to disable (enabled is default) then click the save now and apply the settings. The light should be out now meaning you don't have the Secure Setup feature enabled.
    It is just a personal choice to have it on or off, it should not affect router or internet performance unless you hit the button trying to connect a device to the network.

  • Can someone explain shortest path switch over in Multicast?

    Can someone explain shortest path switch overin Multicast?

    Hi,
    Shortest path switchover is used in PIM Sparse mode.
    The concept of Sparse Mode is the multicast traffic should only be delivered when there are active receivers in the network. To accomplish this SM has explicit Join and Prune mechanism rather than Flood and Prune used by Dense mode.
    When the last hop router (where receiver is connected) receives an IGMP join message, it sends a PIM Join towards RP. This creates shared tree from the last hop router till RP along the routers.Thus a shared tree has been created from last hop router till RP.
    At the same time the above procedure was taking place, the first hop router (where source is connected) starts sending PIM Register messages to RP (when source starts sending multicast traffic). This register messages are unicast so that the intermediate routers will not aware of multicast traffic. When the RP receives Register messages from first hop rotuer, it does below checks after decapsulation:
    1. Are there any shared tree for the specific multicast group. If yes then send a SPT join towards first hop router so that the multicast traffic from source will be delivered to RP via native multicast rather than encapsualted packets. Also RP sends Register Stop message to inform first hop router to stop sending encapsulated multicast packets.
    2. When there are no active groups in RP (i.e RP has not received any PIM join for the multicast group from any last hop router), RP sends a Register Stop message.
    By this the traffic from source flows via SPT till RP. From RP it flows via shared tree till receiver. Everything is fine till now. But the drawback in SM is placement of RP and the load on it. Since RP is located in a central location chances are there that the multicast traffic from source takes a longer path to reach the receiver. This will result in increase in latency along with increase in RP load.
    So in those cases, it is desirable for the multicast traffic from source flows to receiver on optimal path. This is done by SPT switchover and this is done when the multicast group traffic crosses the SPT threshold configured. In Cisco the default SPT threshold is Zero kbps. So when the last hop router receives first multicast packet via shared tree, it does SPT switchover. This is done by sending a SPT Join towards the source thus bypassing the RP. Now the traffic from source prefers the most optimal path to reach the receiver.
    The same time, last hop router sends a PIM prune towards RP to inform it that it does not want multicast traffic over shared tree. This is done to avoid duplication of the multicast packets over SPT and shared tree.
    Few facts:
    1. Last hop router needs information about the source to send SPT Join and this can only happen when it receives few initial multicast packets via RP shared tree.
    2. If you do not want the last hop router to fall back to SPT switchover, then configure SPT threshold to infinity in last hop router.
    Sorry for the long post.
    HTH.
    thanks

  • Can someone explain how to set up an administrator account so that I can have my phone and my daughters have separate apple ids?

    I mistakenly updated to the latest version of iOS and ever since then I can send messages to my daughter and I receive them but she does not.  She has an iphone also and her phone is under my apple id also.  Someone told me that I could set up an Administrator Account so that she can still be under my account but she has her own ID and that will fix the problem with text/imessages.  I can't find anything on the website that explains how to do that.  Can someone explain that to me?
    Thanks!

    I'm still not clear on what you are trying to accomplish. If you have an iPhone and she does as well you should have your own Apple IDs.
    If you want to pay for any purchases she makes with her phone as far as apps/music goes than that is what Family sharing is for.
    In my case my Wife and I are setup for family sharing. When she purchases music/apps it charges my credit card. This setup also allows me to share my past music/app purchases with her and vice versa.

    Exchange 2010 "This message could not be sent. Try sending the message again later, or contact your network administrator.  Error is [0x80004005-00000000-00000000].
    In a mixed client environment, mostly Outlook 2010 & 2013 clients. Only Outlook 2013 clients (about only 4 mailboxes) are receiving this error immediately after sending an email. My temp band-aid at the
    moment is to: from the client, go into the "address book" & select a different address book like "Contacts" & then select the address again & select the Global Address List, which is the default. (it will have the users email
    + at the beginning of the field, it reads, Global Address List - (email of the user), then I close Outlook & open it back up, & the problem is solved. But on some mailboxes, not all, the issue comes back. From my research, I know that our individual
    mailboxes do not send out over 500 emails in one day. Most users will send out maybe 20 or 30 in one day, so I don't think it's that. 
    But I'm not sure if this is related, but I have noticed that the log files for the Exchange 2010 seems to only hold logs with date stamps of only a couple of days. It used to hold log files indefinitely until they were archived, deleted, etc. So, this is
    a new, unusual issue I have seen as well. 
    We have 2 .edb's, one active: 78 GB's and one disabled at 7 GB's. Exchange 2010 is running on Windows Server 2008 r2, Enterprise Ed. We have had Exchange 2010 running now for about almost 2 years now and this is the first time this particular issue has come
    up.
    Thanks.

    Hi,
    You can refer to the following steps to rebuild an Offline Address Book.
    1. Open EMS. Update OAB using the Update-OfflineAddressbook "offline address book" cmdlet. Restart Background Intelligent Transfer Service on the Mailbox server.
    2. Initiate OAB replication from mail box server to CAS server. Execute for each CAS server using the Update-FileDistributionService "CASServerName" cmdlet.
    3. Start Outlook and download OAB.

  • Trying to understand RSTP - Please can someone explain this?

    Hi Group
    I am still confused about how RSTP is implemented. From what i understand the major difference is that STP
    used Timers for Loop prevention whereas RSTP coordinates between neighbors via messages (proposal/aggreement) to turn on links
    more quickly after topology changes and is "timer free".
    However, I have not noticed any difference in the configuration from the legacy STP
    configurations and the RSTP configuration on cisco devices. Or are there any differences??
    I have read in documentation that RSTP natively includes features like UplinkFast, BackboneFast and PortFast. So are these features now obsolete
    and not needed to be configured if you are running RSTP. (Although i have seen Portfast still configured along with RSTP on many switches)
    Also can someone explain the below Points from Cisco Documentation
    1) should STP be disabled on edge ports all together as suggested below?
    "STP edge ports are bridge ports that do not need STP enabled, where loop protection is not needed out
    of that port or an STP neighbor does not exist out of that port. For RSTP, it is important to disable STP
    on edge ports, which are typically front-side Ethernet ports, using the command bridge
    bridge-group-number spanning-disabled on the appropriate interface. If RSTP is not disabled on edge
    ports, convergence times will be excessive for packets traversing those ports."
    2) It seems RSTP relies on duplex setting to determine inter-switch links. What is the configuration to explicitly
    configure RSTP link types? (I couldnt find this in the documentation)
    "RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to-point links.
    The link type is automatically derived from the duplex mode of a port. A port that operates in fullduplex
    is assumed to be point-to-point, while a half-duplex port is considered as a shared port by
    default. This automatic link type setting can be overridden by explicit configuration. In switched
    networks today, most links operate in full-duplex mode and are treated as point-to-point links by RSTP.
    This makes them candidates for rapid transition to the forwarding state."
    Also i am a bit rough on my RSTP knowledge even after skimming a few Cisco documents. Can someone please explain this in simple way.
    Thanks in advance

    to configure it on a device:-
    spanning-tree mode rapid-pvst
    PortFast/UplinkFast & BackboneFast were cisco "Enhancements" to 802.1d STP. RSTP just incorperates them. If you want to configure portfast, the command is still "spanning-tree portfast"
    OK
    1) That is your choice - I have bitter experiance of users/IT admins just plugging hubs/switches in when ever they can. Also cabling the switch back to itself creating a cabled loop. So my advice to you is to leave STP enabled on all switch ports, BUT enable BPDUGuard - this is a life saver, if you have configured portfast.
    2) duplex auto! or duplex full (overiding)
    I really suggest that you read the 802.1d standard, once you understand normal spanning-tree - RSTP will come to you.

  • Can someone explain how data is fed to the usage details screen in My Verizon?

    Can someone explain to me how I can view my data usage for a past date today and when I look at the same date a few days from now there will be additional data. Customer support were adamant that the data usage details come directly from my device so I commented that my device must be saving usage and sending it to Verizon arbitrarily to which I was met with silence on the line.
    Here's an example - on 4/1 I checked my data usage details for the date of 3/21 and it looked like this:
    03/21/12
    08:43:00 PM
    0.02518
    03/21/12
    09:17:00 AM
    0.01475
    03/21/12
    07:20:00 AM
    0.01730
    then on 4/7 when I checked my data usage details for the date 3/21 it looked like this:
    03/21/12
    11:45:00 PM
    1.15382
    03/21/12
    11:38:00 PM
    0.24853
    03/21/12
    08:43:00 PM
    0.02518
    03/21/12
    07:50:00 PM
    1.03191
    03/21/12
    06:55:00 PM
    1.18499
    03/21/12
    06:10:00 PM
    1.03968
    03/21/12
    09:17:00 AM
    0.01475
    03/21/12
    07:20:00 AM
    0.01730
    The red rows have been added between 4/1 & 4/7, but where did they come from? This is just one example, it's happening all over my bill and Verizon cannot justify the anomaly and certainly won't consider removing the $40 in overage charges I have this month. Which brings up another question, why doesn't Verizon offer more than 10GB for the mifi? If I want to use more data and am willing to pay for it, I have to go to another provider?

    Hi kellieh,
    When you had your data overage (and the additional spurious charges), how did Verizon respond to you?
    I have just reported a 2x discrepancy between individual device data usage (.89 GB total) and the reported 1.5 GB for my account.  They claim it will take 72 hours to get back to me after they research the problem.
    What avenues did you pursue to make contact?
    I caled 611, then emailed tech support, then sent a private message to Verizon Wireless support.

  • Can someone explain purchasing, activating and signing up for iPhone.

    Hi, iPhone hits UK in November and I'd like to be prepared. Can someone explain to me how it's going to work. In the USA where do you buy the phone - the Apple store, and what do you do just walk in a buy the actual phone as if it were an iPod? And then how does activation work? What is it, just registering the iPhone with Apple or signing up with the network provider? What stops you from just buying the phone and putting another AT&T or O2 sim in and not signing up for one of the contracts?

    Presuming that it will look pretty much the same as it did for US customers, it will be something like this..
    You walk into your local Apple store and purchase an iPhone, or you can order one through the UK online Apple store (or, presumably, O2 will sell them in their local shops).
    You connect the iPhone to any computer which meets the minumum system requirements. It will recognize a new, unactivated iPhone and take you through the activation, which includes:
    1. Entering your name, address, and payment info
    2. Create an iTunes Music Store account if you do not already have one
    3. Select which type of call plan you want (how many call minutes, how many text messages, etc)
    4. Specifying whether you want a new number assigned or want to port your number from another provider (assuming this can be done in the UK)
    You will then wait while the activation is completed, which can take several minutes. Once your phone is activated you will be able to make calls, send text messages, and use all the other functions of the iPhone, including syncing your contacts, calendars, and music to it. If you are porting a number from another service, once the port is complete you will be able to receive calls. If you are being assigned a new phone number, you will be able to receive calls right away.

  • Can someone explain me well when the infopackage use batch or dialog?

    Hi Gurus,
    can someone explain me well when the infopackage use batch or dialog?

    Hi ,
    first of of in Bi_btch job nothin comes in the log .. but if you use PSa and then into data target then it willl definatly create background jobs .. but i feel it doesnt relate to the concept you are taking about ..
    if you us e a sepeate update from PSA step the it will create backgroung jobs ..of  king bi_btch and if you push the packets maually then it will create jobs like bi_book .. thats the diff ..
    The initialization and execution of an InfoPackage is implemented as a process type in the process chain maintenance. The Start Later in Batch setting is hidden if the InfoPackage is used in a process chain. This is because the start of the request is determined by the process chain itself.
    If you do not use the InfoPackage in the process chain maintenance and you want to process the data request in the background, select the radio button Start Later in Batch and define the required start time. If start times already exist for this data request, this is indicated with a  next to the Scheduling Options pushbutton. You can change the start time using Settings Options. You can also enter an end date for the data request with a background job.
    If you schedule an InfoPackage in the batch later, the background request job runs until all data is updated in BW. This is displayed with a corresponding indicator in the Schedule tab page.  The load process remains active until the data is updated.
    For example, this gives external scheduling tools the option of monitoring the request job. The job then also runs with a request from an SAP source system as long as the source system has sent the data to the BW system and posted it or until the monitor sets the request to red. In the job log, a success or error message is displayed according to whether the request was posted successfully or not.

  • Please can someone explain how to delete email addresses?  I have people who when I type in their name it comes up with the correct email address but then when you hit return to confirm it promptly changes the name to someone else (always the same someone

    Please can someone explain how to delete and email address that when typed in brings up one name but when you hit return to confirm it jumps to another name.  I can't find them in my contacts list but they do come up when you type the first few letters of a name.
    EG If I type xyz and the name of the person comes up, when I press return to confirm that's the one I want then it jumps to [email protected],  always the same def address.
    I can't fathom it out.
    Thanks
    Terri

    Try this:
    Start a new email.  In the To address bar, type in xyz like you normally do, press return to confim, and when the address you want to remove shows up in the address bar, move your cursor over the address you want to delete.
    A small triangle next to the name will show up.  click on it, a drop down menu will open, click Remove from Previous Recipients List.  Then do the drop down menu again and Remove Address.
    Good luck.
