I am developing my intranet portal in office and created the same environment at home even the domain name and the users I am working with. 

I have taken the backup of site collection through central admin (dont remember if I have selected with security or without) but I did and it created a .bak file.

Later I came home and I went into central admin, created a web application and tried restoring the site using cmdlet.

> 
> Restore-SPSite -identity <http://mycompany> -path
>  "D:\PortalBackup\MyCompanySiteBackup.bak"
> 
> 
> 

After typing Y in Yes it started restoring...but when I tried accessing the site by <http://mycompany>

It's giving me unexpected error. I guess there are permission issues.

Please guide what are the steps I should take to restore site collection from one environment to another.
