Cant Connect to server //SQEW..? WHAT IS THE PROBLEM?

i use microsoft windows XP pro edition

so my problem is when im trying to connect
to my database in SQL server

that error is something like this :
Unable to connect to server //SQEW

Server : msg17, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server Does not Exist or Access Denied

am i have to Add Network Library Configuration
in SQL Server Network Utility

because when i want to add it
in winXP <-- mine
network libraries for shared memory is disable
but for the named pipe is able and something like this
is define as pipe name --> \\.\pipe\sql\query

but in my friend pc ,he use windows 98
in network libraries network libraries for shared memory is
able but his named piped is disable

how i can connect it to the SQL Server?
is there any confoguration method?If you have the IP of the machine runing the SQL Server, use it instead of the name.
Go to the enterprise manager and ad the server there using the IP.
