MySQL local server access (no replies)

Hi,

I create an application using VB .Net 2005 and I'm connecting to a mySQL database install on a Windows 2003 server. I use MySQL Connector 6.2.2 and the database is version 5.0.51a. My application is running very well, but today I had a problem. My Internet connection failed and I was not able to connect to my data, I have an "Unknown error" at the connection?

My database in on my local server, I don't use Internet to connect to. From my client computer, I'm able to see my data through phpMyAdmin. Why I'm not able to see my data from a VB app when Internet connection is down. Anybody have an idea?

Regards,

André
