how to configure SQL 2005 replication

hi, i am trying to configure replication on my local machine where sql server is, and it gives me the following error when
i right click replication–configure distribution, what could be the problem?;

SQL Server is unable to connect to server ‘IS-GODFREY’. (Configure Distribution Wizard)

SQL Server replication requires the actual server name to make a connection to the server. Connections through a server alias, IP address, or any other alternate name are not supported. Specify the actual server name, ‘PSPF-PC’. (Replication.Utilities)
