    I believe this user account would be the administrator for my windows domain. I enter the administrator name exactly as I have been using but the error message "User name is unknown or invalid" keep popping out. What could be the real problem. I could use the same administrator username and password to logon to the server directly, but PDQ inventory keep on pointing this out as an error.

    Keep on having this error message even though I know it is the right administrator name for my windows domain. What could be wrong here? I have my colleagues tried that out but to no avail. We are able to ping our domain (AD) server.

    One issue could be DNS. If you are using the FQDN of the domain (e.g. deadwood.local) try creating an account that used the shortname for the domain (e.g. deadwood). After creating a the new credentials change the background service to use the credentials and retry.
