We are currently running Exchange 2003 on a two node cluster connected to an EMC CX500 for disk space.
We're currently changing all our VLANS / IP Addresses and the below link describes how i am going to change the Exchange IP addresses.
The link describes exactly what i need to do, but i'm running into a problem with item 1d ' Right click all resource groups and take them offline '.
When i do this i get the following message : The cluster resource could not be deleted or brought offline because it is the Quorum resource.
How do i get around this ?
