A port scanner is the tool that would most likely help the analyst determine if the applications are running on a remote server. A port scanner is a software tool that scans a network device for open ports. Ports are logical endpoints for network communication that are associated with specific applications or services. By scanning the ports on a remote server, the analyst can identify what applications or services are running on that server and what protocols they are using. A port scanner can also help detect potential vulnerabilities or misconfigurations on a server.

Adware on the users' machine is a large assumption. If everyone is affected it's unlikely that everyone has adware, and more likely that the server has a virus slowing it down.
The server most likely got the virus from open ports i.e. misconfigured firewall.

Explanation
The administrator should use \server%username% to correctly map a script to a home directory for a user based on username. %username% is an environment variable that represents the current user's name on a Windows system. By using this variable in the path of the script, the administrator can dynamically map the script to the user's home directory on the server. For example, if the user's name is John, the script will be mapped to \server\John.
