Relocate database in a vmware folder

Hi,

I have allocated the mdf and ldf of one of my sql server 2012 databases in a different unit, in my windows server 2012.

The problem is that I'm getting the error 17204 (Access denied) and I think this is because the account/service mssql$wsus used to log on to the database is not in the security of the new unit and I cannot give permissions in the security because mssql$wsus is a service.

Can anybody tell how to fix this problem?

Thanks in advance.

Regards.
