We have a site with a VPN to a client network. In order to transfer files, the client has shared a folder on their domain and set up an account, "CLIENTDOMAIN\ourcompany", to give us access. We are able to access this folder from multiple computers on our domain by supplying these credentials when attempting to access the folder, but one specific user cannot access the folder with these credentials. When the are input, the user dialogue simply reappears and we are unable to gain access. My question is, why would one specific user on our domain be unable to access this remote share, while other users with the same rights (including a fresh copy of the user made in AD) can access it fine?
