Hi Ken,

   does this occur if this switch is simulated too?
That error can sometimes point to a timeout error in trying to connect to the device itself.
Is there anything else going on at that point?
Does it occur even if you step your way through the sequence?
Does it ever occur on a cut down sequence?
You say a "Disconnect All" step. Do you mean you have a step type that does this (i.e. the IVI-C switch step type) or you have this set on the switching tab of another step type (i.e. using switch executive)?
What version of TestStand are you using?
What is the model and manufacturer of the switch? Can you provide the driver install for that switch?
Does it happen in the sequence editor, the operator interface or both? If both, which one does it happen in more?
Which IVI compliance package do you have installed, and what's your version of VISA.

Any other information you think is pertinent would also help.

Thanks
