I am trying to install live Communications Server 2005 on one of our servers, with limited success. All steps complete except the Forest Preperation Wizard, which fails stating:
0x80070057 The Parameter is incorrect.
The log states:
FQDN (our correct domain name)
Root Domain Admin: True
Check Schema Prep State: Success
Create Microsoft Container: Success
Create Service Connection Point: Success
Create Global Settings: Global Settings: Not ready
Any clues what I need to do to install this product?
