Hi
I found a possible solution:
ADO SQL is providing two relevant properties for defining a Time-Out in Visual Basic:
#1 CommandTimeOut
#2 ConnectionTimeOut
The last property indicates how long to wait while establishing a connection before terminating the attempt and generating an error.
In my case, it was set to 15 seconds-what was too short for my query.
Increasing this value to 5 minutes, it is working fine for me.
The question that stays in the room is still why a server suited with 8 core CPU working slower than 15 yrs old server before.
