Cannot login SeagateNAS

is it a domain credential?
Have you tried entering username as  domain\username?

>>is it a domain credential?
no,i am entering the credential which i setup on the NAS for the folder

>>Have you tried entering username as  domain\username?
i am not in a domain environment. but when i enter the ip in the browser or in the run \\192.168.0.2 i get to  see al lthe folders i have creaetd on the NAS and when i double click on the folders i get the login window

let me start by mentioning my NAS is Seagate BlackAmour. Now I have found the issue related to this problem. the issue is that when i login to a folder on the NAS with a user and next time i select a folder which has different user rights to it. i get the error. Now to solve this issue is to somehow logout the previous user and then login with the new user. how do i do this logout or disconnect the previous logged in credential.

windows caches these credentials based on the server not the share - so once you log in to the server the credentials are cached. for that session.

yes exactly. now on the same server i cannot use different users to open a folder on the NAS. for e.g.

i login with user1 which has access to folder1 i do my work in this folder and then i click on another folder which requires another credential say user2.but when i try to login with user2 i get this error. so i need to first clear this user1 from the server and then login with user2
