John,
Yes it will. However, when you attempt to access a PEM of the object, most likely you will get a COM error to the effect that "The RPC server is no longer available.".

Use Type("MyObject.SomeProperty") to check the value of a property of the object instead of the object itself. TYPE() has more robust error checking than VARTYPE() and should be used more often in COM/DCOM situations, IMO. You will get fewer errors cropping up.

HTH.
