Windows 10 Can't access Sysvol by DC UNC server name

[Franckiboy]

Hello

I have a weird issue :

I can access sysvol by \\domain\sysvol or \\dcserver\c$\windows\sysvol\sysvol

but if i try to connect with \\dcserver.domain\sysvol I got a password prompt

In Procmon I've look for the error and I got : 0xC0000201 STATUS_NETWORK_OPEN_RESTRICTION

Last test I did was to connect using \\domain\sysvol and then, unlit the connexion is closed i can access \\dcserver.domain\sysvol path without issue.


I've tested with and without UNC hardening but I alway's finish with the same issue.


Thanks for the help.
