I changed the names and configuration of my servers and installation paths of Exchange 2010SP1 and I can now access the EMC.
This is my configuration, all virtualised using WMware Workstation 7x:
1x DC, Server 2008 Ent, Full Installation.
2x Member Servers, 2008 Ent, Full Installation.
Name of DC = DC, was called vDC1
Name of 1x Member Server = Prime, was called Ex2k10Prime
Name of 2nd Member Server - MBX, was called Ex2k10MBX01
Prime is setup for the following Exchange Roles = Hub & CAS.
MBX is setup for the Mailbox role.
Originally I had also installed the Exchange app on a seperate HDD, this time round I left it in it's default installation path.
Not sure why this is working now but it is, if these settings are what has made the difference this would imply that I cannot use numbers is computer names as vDC1 is not too long a name, or the default installation path cannot be altered.
None of my server names had a "." or space in them, all I have done is removed any and all numbers from the names, kept the default installation path.
