I migrated an SBS 2003 server too Windows Server2008 as a DC, and anoter Server 2008 with Exchange 2010 all hosted on a Hyper-V server. Everything was going good until I decommisioned the old server. The sysvol/netlogon shares were missing which I resovled, replication issues which I was able to resolve.
My problem now is that My DC can ping and access all machines, but nothing can ping or get to the domain controller. I'm trying to search google but nothing is working, any suggestions?
