Which service can be removed when updating a server that is primarily providing web services?

When updating a server that is primarily providing web services, the Windows Internet Name Service (WINS) can be removed. This is because WINS is used for associating NetBIOS names with IP addresses, which is more relevant in environments using legacy systems or applications that rely on NetBIOS name resolution.

In contrast, Dynamic Host Configuration Protocol (DHCP) is necessary for assigning IP addresses to devices on a network, which is essential for web services to function properly. Domain Name System (DNS) translates domain names into IP addresses, which is critical for routing traffic to web servers. Hypertext Transfer Protocol (HTTP) is the foundation of any data exchange on the web and is essential for serving web pages to users, making it integral to the operation of a web services server. Therefore, removing WINS is a reasonable choice as it plays a lesser role compared to these other services in a modern web server environment.
