I changed a server to a new name, and I am able to access the shares via Ip address \\126.96.36.199\shares or from the system via \\localhost\shares but I am unable to access it via its name \\servername\shares. I am able to ping it by name, RDP to it by name, just unable to access the UNC shares by name. I ran into this on a server 2003 box 10 years or so ago and had to update something in the registry, but I can't find where that was. This is a 2008 R2 box. Any idea how I can fix this?
