So my manager goes to put in the new 2008 server at one of our remote offices and finds that replication especially FRS which replicates SYSLOG, is not working with the server in the location. Worked fine when in the main office. So I dig around, and find that in AD Sites and Services, the subnet for the remote site was not connected to the site itself, but to the main office.
Always double check to make sure everything is set right in all palces before say, “Yeah just plug and go!”
