Datasource Undefined After domain name switch

[#1]

Hi

I have CF 11 running with SQL server 2005.

I have a web server running on mydomain.com.  All was well.

I needed to switch mydomain.com to another host off of my network. But I wanted to keep the CF site that was on my network, running under another domain name.
So I registered the domain name  mydomaintest.com and pointed it to my current web server.

All was well, and when I would go to mydomaintest.com, it would go to my current web server.

However, once I switched the domain mydomain.com to point to the new web server, whenever I go to mydomaintest.com now, I get "DATASOURCE Undefined".

Any suggestions?
This was a custom CF site that I did not build.

Thanks
Mike

Also, one more thing. If I try to create  New datasource in CF Admin using my current SQL Server, it won't accept it.
I put in the name of the Datasource and select SQL server as the type, but when I submit it, it just blanks out.

Thanks

Open the ColdFusion Administrator. Go to the Data Sources page.

I am assuming that you had previously configured some data sources. If so, press on the button to "Verify All Connections". What is the result?
