Windows FileCluster Server 2019 in 2 nodes, DFS at 3 DC´s, clients mixed.

When accessing a dfs share it takes up to 7 seconds to see files. Then it will be cached for round about 1h, then again waiting times.

Access based enumeration check with or disabled does not help.

Setting a bigger timeout/cache time does not help.

No Ideas anymore.

No issues with a "normal" share on the same server.

    Hi,
    Do you have multiple sites for the clients and DCs?
    When the clients access the shares ,were the access across sites?
    How did you set the following configuration:

    I would recommend you capture a network package for more details when access the shares. (it is not recommend posting here due to the security and policy reason )
