    We have a blog at companyname.blogspot.com and our web host service has set
    up or public dns so blog.companyname.com forwards to it. I'm trying to get
    that to happen internally, the domain is companyname.com. I tried an alias
    record for blog pointing to companyname.blogspot.com but that doesn't do it.
    I tried a host with blog pointing the public ip address for
    blog.companyname.com but that brings up a google server saying no such page.
    How can I accomplish this?
    Thank you.

  2. You need to create a zone called blogspot.com, and create a host record
    called companyname, and provide the internal IP.

    thank you, but I don't understand what internal IP to use.
    what I want to happen is, when you enter blog.companyname.com into a
    browser, that goes to companyname.blogspot.com.

  4. It is not an internal IP#,...it is a public IP#

    Problem,... once you create a Zone called "blogspot.com" then your own DNS
    becomes authoritative for that domain,...meaning that any and all other
    bogs/sites hosted by "blogspot.com" will be unreachable to you unless you
    create records for them in your own DNS which is basically impossible.

    What you did originally in your DNS by creating a Host entry called "blog"
    and give it the Public IP# of the blog *should have worked*. You had to
    have done something wrong there,...that is what you need to look at. The
    CNAME you created should have worked too,..don't know why it didn't.

  5. Then I misunderstood he initial post. I thought, an construed as the way it
    was explained, that his web server is internal, hence the reason for my
    suggestion, not realizing that 'blogspot.com' is an actual external domain.
    Yes, I've heard of it before, it just didn't hit me that it was the same.

    So then if the zone is external, I'm curious if from an external location
    (not in the network), whether http://companyname.blogspot.com works?

    the problem is, the public IP for companyname.blogspot.com, when I ping it to
    come up with an IP, then plug that into a browser, it comes up with a google
    server error message saying the page doesn't exist. (blogspot is google, you
    know)
    In fact, ping any whatever.blogspot.com blog site and browse to it, and you
    either get an error or the standard google home page.

  7. I see. I didn't know blogspot is a Google thing, since I've never used it.

    They may be using a webfarm controlled by hostheaders, so it has to be
    connected by browser using the URL because it redirects to some other URL,
    and they may also possibly be controlling it based on the 'referrer', so
    creating the zone, or creating a cname may not work.

    Instead of using ping, use nslookup:
    c:\nslookup
    You may get a cname as an answer. If that is the case, you can try using
    that name to create a zone. But I kind of think that may not work,either.

    So what is wrong to have your users simply type in companyname.blogspot.com?
    Is it just for asthetics?

  8. well here's the deal, on our external hosted web site, the link is
    blog.companyname.com, it's that way for marketing purposes, and when the
    marketing department clicks on it, "it doesn't work" so it becomes an issue
    for me. But hey, that's life.

  9. Ok, so they 'want' it that way...

    So far, you've created a cname (alias) under companyname.com called 'blog'
    and pointed it to companyname.blogspot.com and it doesn't work, correct?

    And you've also tried creating a hostname record called 'blog' under
    companyname.com pointing to the IP address of companyname.blogspot.com
    (which you got the IP address from running an nslookup), and that doesn't
    work.

    Correct so far?

    Other than that, where is that link that they click on? Is it in the SBS
    CompanySite? If so, how about just creating the link called
    "blog.companyname.com" but the underlying hyperlink is actually
    companyname.blogspot.com? This way to the marketing (and anyone else looking
    at it internally), it looks like blog.companyname.com, but it actually is
    something else underneath.

    OK, here's how Google works, you put in an alias that points
    blog.companyname.com to ghs.google.com. I have no idea how or why it works,
    but it does. BTW, just typing ghs.google.com into a web browser give an
    error page, so how does the alias work?

  11. Searching around, it seems that you are not the only one with this issue and
    trying to redirect your company name to Google's blog site.

    I think the question can be turned around to how Google deals with an
    inbound request using the alias as the hostheader. Google does things
    differently than others. Their forums, which pull/push posts to the
    Microsoft public groups do not follow Usenet RFCs with their headers,
    either. They may be based on the referring URI, or a subdomain using
    something like (this is an example) http://ghs.google.com/yourcompanyname.
    So it's either that, or they are using URI redirection, which would include
    your company name, or whatever name is in your account.

    Maybe these links may help you:

    Per Google's documentation
    (http://www.google.com/support/blogger/bin/answer.py?hl=en&answer=55373)
    you set up the alias (CNAME) to reference "ghs.google.com" like you say.
    Refer to "Updating the DNS Settings => Create a CNAME" on the above URL.

    Then you need to log in to your Blogger (a.k.a. Blogspot) blog and
    change a publishing option. Refer to "Update Your Blogger Settings" on
    the above URL.

    This works because the alias name "blog.companyname.com" is used by the
    web browser to find the web server (via DNS) that is hosting the web
    site that you are looking for. (This is the DNS CNAME portion.) Then
    the web server (or massive cluster that does lots of magic as in
    Google's case) will use your blog name (as configured in your publishing
    settings) to internally handle the blog correctly. Thus you really have
    two things at work here, DNS to find the ""server, and HTTP Host:
    headers for said server to know what web site to serve up.

    What URL do you want your users to see when they (finally) land at your
    blog? Do you want them to see "blog.companyname.com" (probably
    preferred) or are you ok with them seeing "companyname.blogspot.com"?

    If you are ok with them seeing "companyname.blogspot.com", you can
    probably set up a simple web site "blog.companyname.com" that issues
    either a 302 or 301 redirect to "companyname.blogspot.com". In fact,
    this may be what your host service did for external visitors. (I can't
    tell what's going on with out knowing what your domain name really is.)
