When I get time I plan on revamping Scanarator almost from the ground up. There are several things I want to change/add to it.
I am busy with other projects so I will probably not modify Scanarator until I start the overhaul, unless there is a big bug found.

NetQueryDisplayInfo, used in a number of functions, doesn't seem to retrieve all user accounts when run against Win2k. So a user scan on Win2k may not return all accounts. I have run it on an NT4 domain with over 5000 accounts and it does return all user accounts.
UPDATE:
I ran netquerydisplayinfo on a Win2k, native, server with over 3300 user accounts and it found every account every time. Someone reported that Scanarator was not getting all user accounts and I had seen that in the past. It may have been an older rev I don't know but 2.1b seems to get all user accounts. I have also used it on an NT4 domain with over 5500 accounts and it works as well. PLEZ let me know if you find an instance where all accounts are not retrieved or anything else I should know about. Thanks.

INFO:

OOPS found big stupid bug in Release 2.1beta. When you select an output file and browse for the path and also choose tab file it is very ugly. I will try to fix this very soon and release the update. As for now do not browse for your output file just type the file name in so it will be created in the directory you are running Scanarator in and all is well, including the tab file.

If you find any bugs or problems plez email me.
