We've got 2 sites in AD with 1x Server 2008 R2 servers in each. The main one (in the site called OFFICE) is the Schema master. We are trying to install Exchange 2010 to another server at a remote site (in the site called REMOTE) and keep getting the error above.
I have ran preparead in the office site server and updated the schema. I have also checked schema versions and both servers match so they are the same.
I can ping from either server to the other and there is a static VPN between them but i can't seem to get past this error.
any help would be great.
