I have had the same issue with same Windows version for some time now. Read about the SMBv1 in other topics and windows networking but always saw many disclaimers about *Do not re-Enable* based on security purposes. Thus, I haven't done this and now rely on AD browsing in DRS or DMRC to access machines. I wish Solarwinds would update the program to fix this or at least fix what it can.
Another issue I am seeing is in DRS the "Processes" of a remote host are not showing either, thus trying to view or kill them in DRS is no longer available.
Please fix this program. I hope this program isn't on the chopping block but it sure does appear that it could be headed that way.
