We have a DFS namespace consisting 4 virtual servers running window server 2012 as shown below.
The 4 servers are located in 2 different AD site, with 2 server running in AD site 1 and another 2 servers running in AD Site 2
AD Site 1 | AD Site 2 | ||
Site1_fs1 | Site1_fs2 | Site2_fs1 | Site2_fs2 |
The referral list order is as follows:
- Site1_fs2 (first among all targets)
- Site2_fs2 (first among targets of equal cost)

Dfsutil Output from Site1_bzt1b
Base on the above information, we would like find out
- From the above dfsutil info, one of the node, SITE1_FS1, is indicating “AccessStatus: 0xc00000be ( TARGETSET )” . What does this access code meant ? Will it have any impact on the DFS performance ?
- If all the DFS nodes (Site1_fs1 and Site1_fs2) in AD site 1 goes down, will DFS clients be automatically route to the DFS nodes residing in AD SITE2
- Should the Site1_fs2, goes down, and Site1_fs1 is still working, how can we force DFS clients to target DFS nodes residing in AD SITE2 when it access the DFS namespace without shutting down Site1_fs1
