Recently, I have come across a situation where certain machines would replicate everytime the data storage folder is refreshed. Even after the machine is placed in a group, a duplicate entry within its original grouping (domain name) would appear. Evertime after that when the data storage folder is refreshed, another entry would appear so that if I refreshed 4 times, there would be four different entries for the same machine.
Any Ideas? I tried restoring an old groups.dat file but to no avail.
