Dollar sign behind user name

What does the $ (dollar sign) means behind the SQL Server login?
I had a SQL Server login something like this "DomainName\User$".
Peter ChanThis is generally a computer account. If a service runs under Local System
or Network Service on a remote computer it can be allowed access to SQL
across the network via it's computer account (which is the credential it
passes over the network)
