We have a SQL app that references a dfs path to store and access JPGs. The data is replicated between 2 2008 R2 servers, when the DFS ordering is set to over ride the order and prefer server 2, or using the unc path to either server, all works fine. When the over ride setting is not configured, or favors server 1, invalid path or filename errors occur. DFS seems to be working otherwise, replication is fine and other files can be accessed, There are a large number of files in the folders having the issue, close to 2 million pictures, not sure if that has anything to do with it, any ideas? Thanks.
