VMware vSphere Host currently has no management network redundancy.

Resolution

This message appears if the Service Console does not have network redundancy configured properly and can be safely ignored.

To prevent this message from appearing and to comply with proper network redundancy, VMware recommends that you add a second service console on a different vSwitch and subnet. Alternatively, you can add a second vmnic to the service console vSwitch.

To suppress this message on ESX hosts in the VMware High Availability (HA) cluster or if the warning appears for a host already configured in a cluster, set the VMware HA advanced option das.ignoreRedundantNetWarning to true and reconfigure VMware HA on that host. This advanced option is available in VMware Virtual Center 2.5 Update 3 and later.

Note: If the warning continues to appear, disable and re-enable VMware High Availability in the cluster.

To set das.ignoreRedundantNetWarning to true:
  1. From VMware Infrastructure Client, right-click on the cluster and click Edit Settings.
  2. Select VMware HA and click Advanced Options.
  3. In the Options column, enter das.ignoreRedundantNetWarning.
  4. In the Value column, enter true.

    Note
    : Steps 3 and 4 create a new option.

  5. Click OK.

How to fix OAB not updating in Exchange 2007

The way we fixed this was by going into Exchange Management Console (EMC) , Organization Configuration , Mailboxand then clicking on the Offline Address Book tab. Double click on the Default Offline Address Book then click on the Distribution tab and untick “enable web based distribution” .OK out of this menu, then go back in and retick the “enable web based distribution” , add the servers that you want to use for web distirbution and OK back out again.

You should now have an updated OAB when you download it again.

Another point to note is that if you have multiple Exchange servers is that you should have all of the servers are added in for “web based distribution”
