Do all DFS nodes have dfs referral information stored?

Hi,
This is a question related to SMB2_STATUS_NOT_FOUND
When we are making FSCTL_DFS_GET_REFERRALS, IOCTL call to some specific random server in dfs setup. e.g. <server>/$IPC, few of the times we are hitting SMB_STATUS_NOT_FOUND.
The question is: is there a certainity where all dfs nodes will have global(all) dfs referral information or can it happen so few nodes might not have the information in dfs cache.
This thread hints at the latter might be the case:https://social.technet.microsoft.com/Forums/windows/en-US/fb8adefa-7128-46f7-a67e-b36feed2d31a/0x80070043-the-network-name-cannot-be-found?forum=winserverfiles
Can someone confirm this.
Thanks

    Hi ,

    Thanks for your posting here.

    I did not find any related information from Microsoft official document. I would suggest you contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation to this question.
