Time out settings to fix "The Open Operation did not complete within the allotted timeout of 00:01:00."

Does anyone know which time out settings I should change so that this error will not come up again?

This problem resolved after I added more resources in the Hyper-V Manager for the Epicor SQL Server.

Making sure this value is set to 100.

Virtual machine reserve (percentage): 100

Hello, we have the same error after the app server was moved to a virtual machine. Could you write what your virtual machine parameters are? Thank you!

Suggest you run the Epicor Performance Diagnostic tool. I think I upgraded the VM to use SSD.
