Error When Running UserEnum_RPC.py

[kerbroasted]

Hello,

When running UserEnum_RPC.py with the following variables I get the following error.
./UserEnum_RPC.py 192.168.1.97 userslist.txt

Error:

Any ideas what this might be?

Hi,

seems to be an issue with impacket when you install pycryptodome, as discussed here:
fortra/impacket#349

Try to run pip uninstall pycryptodome, or use virtualenv with only the required python packages.

Let me know if that works.
