Hi ,
We use DFS on Windows Server 2008 R2, Every once in a while (around 15 days) the DFS Server looses connectivity to the DC. After few minutes is resumes the connection back. What causes this in the first place? My DC looks healthy and passes all the tests.
Below are the DFS Debug logs at the time connection was lost:
