Concurrent Connections in Windows XP

I was recently asked a question by a client who had a Windows XP system setup as a “server” to share common files and databases in a small office of about 20 people. The plan was good, but the client was confused why more people could not access the “server” resources.

One of the limiting difference between Winsows Server software and Windows client software (such as XP) is that XP only allows 2 concurrent connections to the system. This assumes an Admin and a User can simultaneously be connected.

As it should be. You bought Windows XP software for a computer. Licensing requires the software can only be used by 1-2 users at a time. So why would 20 people be able to use Windows.

Windows XP is client software. It is intended for use on a workstation or a laptop. If more than one person is using the resources, it is accurately assumed to be a server in which case, the client should be using Windows Server (probably Windows Server 2003). Server 2003 allows 256 concurrent connections with more available for Enterprise software.

For more information, Microsoft has a breakdown comparison on features.
