DFS is great until it isn't! If you DFS is slow or timing out check if any of these solutions fixes your problem.

DfsDnsConfig

Registry Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dfs
Name: DfsDnsConfig
Value: 1

This causes DFS Referrals to use FQDN. This needs to be set on all DFS servers, not just your file shares. If your DFS-Namespace is stored on a domain controller, then DfsDnsConfig=1 needs to be set there as well.
