Connecting to Project Server 2003 from MS Project Profissional

[Queenie]

Hi,
I just installed Project Server 2003 on Windows 2003
enterprise Server. I
created a user on the project server. I
configured the Office Project Profiessional(on the other
machine) to connect to this server.

When I open the Office Project it tries to login to the
server but it failed
and gives me the following error message
"Cannot Connect.

Project was unable to establish a connection with the
selected project
server. This could be caused by the loss of network
connectivity, invalid
user name or password, lack of an enterprise global
template, or problems
with the project server or database, or your project
server may not have
enterprise features enabled.
"

I have made my server location a trusted site in IE. And
From the admin page in PWA, i have my "Enable Enterprise
Features" checked on. Im sure that my username and
password is correct.

Moreover my project pro can connect to the project server
if the project pro is installed in the project server's
computer.

Please anybody can help me in that?

Thanks in adavnce for any help.
