    2. Name the text file sbsAllrolereinstall.ps1, and then save it in C:\windows\system32.
    3. Open Exchange Powershell: Click Start, click All Programs, click Microsoft Exchange Server 2007, right-click Exchange Management Shell, and then click Run as administrator.
    4. On the User Account Control page, click Continue.
    5. In Exchange Management Shell, type .\sbsAllrolereinstall.ps1, and then press ENTER.

    1. Click Start, click Administrative Tools, and then click Internet Information Services (IIS) Manager.
    2. On the User Account Control page, click Continue.
    3. Expand the name of your Windows SBS 2008 server, and then expand Sites.
    4. Click Default Web Site, and then click Start.
    5. Expand SBS Web Applications, and then click OAB.
    6. In OAB Home, double-click SSL Settings.
    7. Select Require SSL and Require 128-bit SSL, and then click Apply.
  3. To send e-mail messages to the Internet, run the Fix My Network Wizard by doing the following:
    1. Open the Windows SBS Console.
    2. On the navigation bar, click Network, and then click Connectivity.
    3. In the task pane, click Fix my network.
    4. Follow the instructions in the wizard. You can click each potential problem that the wizard lists to get more information about the problem. To recreate the default Send and Receive connectors to re-establish mail flow, select Exchange SMTP connectors are invalid.
  4. Rerun the Internet Address Management Wizard to associate the new virtual directories with the correct external URL.
  5. If your server uses a trusted certificate, you must also run the Add Trusted Certificate Wizard.
  6. You may end up with the exchange saying its not license you can register Exchange on SBS with this tool.

  1. Thanks for the info first up…
    having execution issues with the script.

    Incomplete string token.
    At C:\Windows\System32\sbsAllrolereinstall.ps1:55 char:117
    + New-OWAVirtualDirectory -WebsiteName “SBS Web Applications” -OwaVersion “Exch
    ange2003or2000? -VirtualDirectoryType “E <<<< xadmin" -ExternalAuthenticationMe
    thods Fba

    the script stops here – any ideas – any help would be appriciated

    Steve

    • it looks like maybe in the copy past the quote got messed up, I have seen that happen with pulling off a blog before though havent seen it yet on this one.

      I think you may just need to fix the quote where its a ? change to ”
      New-OWAVirtualDirectory -WebsiteName “SBS Web Applications” -OwaVersion “Exchange2003or2000? -VirtualDirectoryType “Exadmin” -ExternalAuthenticationMethods Fba

      in short go through and verify that what is in the script matches txt on the post. also replace the ” after the 2000.

      also you dont HAVE to run it as a script you can run 1 line at a time, that way you see the results of each.

  2. Hi,

    I know this is an old guide but I’m hoping you can help with your script, I am getting the following error:

    Incomplete string token. At C:\Windows\System32\sbsALLrolereinstall.ps1:57 char:117 + New-OWAVirtualDirectory -WebsiteName “SBS Web Applications” -OwaVersion “Exchange2003or2000” -VirtualDirectoryType “M <<<< ailboxes" -ExternalAuthenticationMethods Fba

    Any ideas?

    cheers

    • Based on your reply it looks like a space may have been inserted in the -virtualdirectorytype “Mailboxes” maybe retype quotes and mailboxes. Some times the text doest copy correctly

      • Hi,

        Thanks for getting back to me – I have tried re-typing this part I wonder if there is another part of the script that has an issue as I had some problems with characters when pasting from wordpress.

        Are you able to stick the original working script into pastebin or something for me?

        The full script I am using is here:
        http://pastebin.com/bdkEw7mq

        any help would be greatly appreciated

      • sorry for the late reply, things have been a little nuts lately.

        so I took a look at the link you provided and it looks like you have “&#8221” throughout the script, I think removing those (not sure where they came from) should resolve.
        also I pasted the original txt to pastebin as requested.
        http://pastebin.com/hRcPaSXA

        Be sure you are running this on the correct version of exchange\SBS as vdirs change from version to version.

  3. No probs,

    Ah must of been something that happened when copying it,

    I’ve just run the one from pastebin, success! thank you!
