RDP Sessions

@WillFulmer I have not tried again since then -- did not seem to be a collector issue, more that the Powershell involved was too intense.  Worked fine in a few cases, but when the server count was in the 80+ range (which is no problem normally), the collector bogged down and lost data until we disabled it.  I have not had a chance to go over the code too much to see how it could be made more efficient.  It may not be possible...
