I installed Exchange server 2010 on new Windows 2008 Server. When start exchange and go into Microsoft exchange on-premises it errors out: "The following error occurred when searching for On-Premises Exchange server: Execption calling "GetComputerSite" with "0" arguments: "the Specified domain either does not exist or could not be contracted. "it was running the command 'Discover-ExchangeServer -UseWIA $true'. " How can I fix this?

What is your environment like is this one domain? How many DCs do you have are both functioning correctly? Run dcdiag on your DCs and report any problems.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

We have AD server on one VM and we have this exchange on another VM. I got this. Performaing initial setup: Trying to find home server... ***error: branchexchange is not a Directory Server. Must specify /s:<directory server> or /n:<Naming Context> or nothing to use the local machine ERROR: could not find home server.

Did you run dcdiag /s:yourDCJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
