I create an application in VB.net which connects to MySQL, deployed it to 10 computers. 8 of them worked perfectly, 2 of them gave me the error:
Unable to connect to any of the specified MySQL hosts.
What was different with those 2 computers? Is there any setting I need to do on the MySQL server itself? Anything I need to change/update on those two computers?
What is different about those machines? Are they running a different OS (Vista or 7)? You may want to check the firewalls on those machines to see if they are blocking outbound connections for your application.

There's one place that has 3 computers connected to one router. The other two computers worked perfectly, one gave me the error.

I pinged the mysql server address and it worked on the two that connnected. The one it didn't work on gave me a request timed out.
Is the network segmented?
If so, are the two computers that won't connect on the same network segment as the eight that will connect?
i got it. Thank you for the response. Here's what I did
and it did it.Code:ipconfig /flushdns
ipconfig /registerdns
