Alternate Access Mapping Configuration RRS feed

  • Question

  • I am new to SharePoint. I have read through few articles explaining the AAM but I still not sure about its configuration under this deployment scenario.

    SharePoint 2007 (AD domain- xyz.net, Public domain- abc.com both hosted locally)

    Note: Servers and users were joined to domain xyz.net. Users will access the portal either from internet or intranet.

    2 WFE (servername: abcweb01, abcweb02)

    2 SSP (server name abcapp01, abcapp02) both SSP was disabled the web site using port 80.

    1 hardware load balancer (preferred external url provided for the portal: net.abc.com,  preferred internal url provided for the portal: internal.abc.com)

    Current AAM setting:

    Internal URL                               Zone                         Public URL

    http://abcapp01                          Default                      http://abcapp01

    http://internal.abc.com                Intranet                     http://internal.abc.com

    http://net.abc.com                      Internet                     http://net.abc.com

     

    Question:

    What should be the correct AAM configuration for this scenario? The preferred internal url shouldn't using public domain name right? I have encounter error "the access web datasheet is attempting to retrive data from a different domain. You will be redirected to an error page." when I click Edit in Datasheet. This error only occur when I access the portal from Internet using url http://net.abc.com but no problem when I access the portal from LAN using servername http://abcweb01. People suggested that it was due to AAM configuration. Appreciated if anyone can show me a clear picture of this. Thanks in advance.

  • Hi Mike,

    I have configured Internet zone with url http://net.abc.com so I cannot confiugre it as as Default zone. I have configure the two Default url as http://abcweb01 and http://abcweb02. Later I try to get a load balance virtual hostname put it as default zone instead of using two web front end servername.

    As mentioned in my initial post, when I access using the internet url http://net.abc.com and click Edit in Datasheet action, it show error "the access web datasheet is attempting to retrive data from a different domain. You will be redirected to an error page." and then show error page with mesage "the list cannot be displayed in datasheet view for one or more of the following reasons: a datasheet companent compatible with windows sharepoint services is not installed, your browser does not support activex, or support for activex control is disabled." Do you have any idea how to tackle this problem? I have no problem to access the portal using url http://servername in intranet.

    Thank you for your help.

  • Hi Mike,

    I have tried you suggestion. I realized that the error was due to inconsistency of AAM setting in Central Amin hosted on SSP servers and WFE  servers. When I made a change in Central Admin, the setting somehow cannot sync to others Central Admin in the SP farm.

    If I change the load balance url as default zone url, I will have problem accessing Mysite. This i because when I installed the first SP server and created the SSP, I created Mysite under it as well. If I change the default zone url, I will need to migrate Mysite to WFE. So, I was told to remain the previous AAM setting and let the hardware load balancer to do the job.

    Anyway, thank you very much for your suggestion.

  • My gut feeling is that having a default pointing at the SSP is wrong and that you would normally be pointing at the front-end which in this case would mean the net.abc.com.

    It's worth trying anyway.

  • > I have configured Internet zone with url http://net.abc.com so I cannot confiugre it as as Default zone.

    Sorry, I assumed wrongly that it was obvious that this meant changing where net.abc.com was assigned.

    Accessing the server name will always work from the Intranet. But the server name is not available from outside the local network.

    The idea behind my suggestion (and it was - I repeat - only something that is worth trying) is that net.abc.com would be accessible both from inside and from outside. DNS takes care of converting that to server name once it has been accessed.

  • Hi Mike,

    Actually, what is the usage of Default zone? When will we use it? Since I had intranet url and internet url for access already, why I still bother with the Default zone url? The net.abc.com is resolved to public IP and not available for local network

    > Accessing the server name will always work from the Intranet. But the server name is not available from outside the local network.

    The net.abc.com is resolved to public IP and not available for local network, we still put it as default?

    Anyway, I will try it out tomorrow and update the result.

  • Default zone is needed because it is the URL that is used for the internal links on the SharePoint site.

    Hence it usually being servername. 

    But AAM by itself is useless without a correctly set up DNS.

    So that is why I also mentioned DNS. As servername is not available from outside the network you need to set the DNS so that the name that is available from outside the network is converted to servername.

    It's been quite a while since I did this in a major way so I'm floundering to explain. But the key thing is the combination of AAM and DNS - DNS gets  you to the correct machine; AAM then makes sure that the internal links (and not just the default site) also work (as otherwise they stay at the external name + internal path and that won't work).

    I've always found that if it doesn't work at first, trial and error gets me there.

    [One thing to note is that the only one you need to get right is Default Name. Whether then the Intranet address is called Intranet or Internet or Extranet is irrelevant. ditto Internet address etc. Those are just names useful for documentation.]

    If you can't get it to work based on the above, someone else with a more scientific approach to this needs to come in.
