Hi Marcos,
Yes, I agree, and this was why I admitted it to be not an ideal solution. The reason for wanting to consider it is that on one network there is a subset of PCs that are old and slow and there are complaints about the slowness that I cannot verify firsthand and I was wanting to try a scenario where I know that the definitions are not updating during the day so they would not be slowing down the PCs with the process that entails. Unfortunately this client will likely not want to or be able to update all the older PCs they have, so I am just considering possible, less than ideal, workarounds.
Thanks again
