Project Server and WSS issues - First Installation

[Bevin]

HELP!

We've installed WSS first using the installation guide for the
single-server installation.

Then installed PS - followed all the steps. Used SQL Server
Authentication.

We get the "Project Server cannot access Sharepoint - check the
protocols" error.

What are some things we can doublecheck to debug?

Both sites work fine outside of project server - we just can't get it
to synch.

New data:
We tried this -
If the default root site is configured to use an incorrect default
custom URL, use Windows SharePoint Services Central Administration to
configure the Windows SharePoint Services site to use the default
custom URL for Project Server 2003. For example, use
http://ServerName/Sites. To do this, follow these steps: 1. Click
Start, point to All Programs, point to Administrative Tools, and then
click SharePoint Central Administration.
2. On the Central Administration page, click Configure virtual server
settings under Virtual Server Configuration.
3. In the Virtual Server list, click the Web site that you created.
4. On the Virtual Server settings page, click Define managed paths
under Virtual Server Management.
5. In the Add a New Path section, type a forward slash (/) in the Path
box.
6. Under Type, click Included path.
7. In the Type list, click Explicit Inclusion, and then click OK.
8. Click Start, click Run, type cmd, and then click OK.
9. Type the following commands at the command prompt, and press ENTER
after each command:
CD "C:\Program Files\Common Files\Microsoft Shared\web server
extensions\60\BIN"

stsadm -o createsite -url http://ServerName:Portnumber -ownerlogin
DomainName\UserName -owneremail (e-mail address removed)

but when we got to this point, it told us that there was something
wrong with the configuration database. Can anyone help?
Thank you!!!!
