LS420DCDA Access issues

[lusk]

I use a CCTV system called BlueIris and when the amount of data on the server C driver gets to a certain amount, the programme moves data from the C drive to a local netowrk drive; in tbis case a Buffalo. All has been working fine up until now and the issue I have is that when trying to open up the share on the server, it asks me for a username and password. When I enter the login username and password,it still won't let me in. On the NAS in question, I have gone to File sharing > folder setup > clicked on the one and only folder there > edit and then disabled all access restrictions. BY doing this, when I use a Win 7 machine to access the share, all works well but when I use a Win 2012 server to access the share, it still wont let me access it and asks for username and password details.

I have gone onto Microsoft website and am struggling to understand what all the different options mean.

Any assistance here would be much appreciated.

Further to my post above, apart from still not being able to get it to function, I have found that if I add another share, then I am actually able to access the share from the server.
