MS Project Server 2003 SQL Server Error: 53 when connecting to SQL2000 using project pro 2003 client

Experts,

I installed Project server 2003 on Server 2003. Followed the instructions by microsoft for single computer installation here  http://office.microsoft.com/en-us/projservadmin/HA011667861033.aspx

Everthing was fine I followed MS instructions above to install SQL2000, SharePoint, and Project 2003 the 1st day.

Install Project Pro on client box connected to database everything was fine the 2nd day.

Next day I open Project Pro on client box and get this error message:

Connection failed:
SQLState: '01000'
SQL Server Error: 53
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).
Connection failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

I noticed I was getting this error on the server under log system log:

Event ID; 4319

A duplicate name has been detected on the TCP network.  The IP address of the machine that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

I remembered I have 2 NICs on this server and had configured them both to have static IPs.
10.x.x.9
10.x.x.25

This I believed was causing the problem so I disabled 10.x.x.25 NIC.

I then opened IIS and set all the websites to 10.x.x.9 instead of *All Unassigned* as they were set previously.

After doing that I am still getting the error:

Connection failed:
SQLState: '01000'
SQL Server Error: 53
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).
Connection failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

I installed all the components needed per the MS install guide and setup all of the users and permissions as it specified. It was working fine for one day and now I'm getting that error. I believe it had something to do with the duplicate name problem but I have fixed that and am able to ping the server from a client via the netbios name.

Expert help is needed here.

Thx in advance

This error just means that the client could not find the SQL Server you are trying to connect to:

Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

Go to the IIS machine and create an ODBC data source to the SQL Server that Project Server is trying to connect to. Test the connection. If that works then something within IIS is doing something wrong. If that fails then there is something going on at the network level or name resolution that is preventing the connection.

Are you still seeing this error:

A duplicate name has been detected on the TCP network.  The IP address of the machine that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

If so it may be responsible for the problem. If it is you need to resolve it first.
