Just installed Server 2008 R2 SP1 on two computers on a simple hub, testing environment only. Can ping each by IP or Name. Not running DNS and no active directory. However, can't get network discovery to work. Enabled network discovery on both PCs via network sharing for network profile.
Using workgroup/ no active directory as of yet, still testing mode.
Can map drive, can ping each other IP or computer name.
Enabled UPNP and SSDP services.
Can't be this hard to do a basic function?
