Small Business Server 2011 Slow to Boot and Several Services Fail to Start

If you uncheck the IPv6 protocol from your network interface card on your Windows SBS 2011 server you may see the following issues after a reboot:

  • Microsoft Exchange services fail to start
  • Server hangs at “Applying Computer Settings…”  (can eventually logon after 30 – 60 minutes)
  • Network icons show as offline
  • Some or all of the following events

This can also happen on SBS 2008 servers when IPv6 is disabled incorrectly/incompletely.

Resolution

To resolve this issue all you have to do is re-check IPv6 in the properties of you NIC and reboot.

NOTE: IPv4 must also be enabled.

Properly Disabling IPv6

SBS 2011, like SBS 2008, is designed to fully support IPv6 and has IPv6 enabled by default.  Most users should never need to disable IPv6, however if you must disable IPv6 here is how to disable it properly:

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 (http://support.microsoft.com/kb/322756/)

  1. Uncheck Internet Protocol Version 6 (TCP/IPv6) on your Network Card.
  2. In Registry Editor, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
  3. Double-click DisabledComponents to modify the DisabledComponents entry.
    Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps.

    1. In the Edit menu, point to New, and then click DWORD (32-bit) Value.
    2. Type DisabledComponents, and then press ENTER.
    3. Double-click DisabledComponents.
  4. Enter “ffffffff” (eight f’s), and then click OK:
  5. Reboot the SBS 2011 server.

RRAS (VPN) Note: If you plan to enable VPN on your SBS 2011 server, you MUST also Export and then Delete the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\RouterManagers\Ipv6

If you do not delete this key you will get an 20103 Event when trying to start RRAS with IPv6 disabled.  You must reboot after removing this key.

Introduction to Exchange Server 2010

To install exchange  Server 2010, you need to firstly extend the schema. You can do this by using these commands and to achieve this you need to be a member of the schema, enterprise, and domain admin groups.

setup /PrepareSchema
Setup /PrepareAD /OrganizationName:ZA
setup /PrepareDomain

NB: Exchange Server 2010 is available only in 64-bit edition and you can make the best of it, if you install it in Microsoft Windows Server 2008 R2. Before installing exchange 2010, you have to install its pre-requisites.

The Initial configurations are as follows: Configure “NetTcpPortSharing” service to start automatic. and install the “Microsoft Filter Pack”

Now you should be able to kick off the exchange server 2010 installation from the setup.

SRP status disconnected

SRP is showing as disconnected on your BlackBerry Enterprise Server Express (BESX).

Resolution: This problem is caused by incorrect SRP ID: Request a new SRP ID and License Key (SRP Authentication Key) from RIM.

Important: If you have ordered the BlackBerry Enterprise Server Express software please make note of the following information while picking up your software:

  • Serial Number (SRP ID)
  • License Key (SRP Authentication Key)
  • Client Access Licenses

Till next time…(for smooth BESX project rollout please drop us an email: sales at magwinya.co.za)

BlackBerry Enterprise Server install option is greyed out.

You attempting to install BESx 5.0 for Exchange on a non-exchange server. BlackBerry Enterprise Server Express install option is greyed out.

Resolution:

On Windows 2008 Server make sure that Terminal Service Role is not added. If so remove Terminal Service Role and rerun BESX installation. I don’t know why this happens but BESX installation fails when your server has TS role.

If you require assistance with BESX project roll out feel free to drop us an email.

Till next time…”If not broken don’t fix”
