MinimWatch fails on Windows 10 Pro

Thanks for this. The problem is shown by the final line in the log file.

12:40:48.735 main: ohNet: Os::OsNetworkSocketMulticastAddMembership H = 475615856, RETURN VALUE = -1

This means your network adapter 192.168.20.12 does not permit IP multicast messaging. It is unfortunate that ohNet does not produce a clearer error message for this problem.

That pointed me in the right direction! Turns out I had multicast support turned off at the adapter level, and had to turn it back on with

Code:

Netsh interface ipv4 set global mldlevel=all

When building Windows 10 I had applied various security hardening defences, and one of them must have contained this.

Thanks for your help I would never have got there by myself, and my continued thanks for such a great product.

Once MinimServer 2 is ready I'll definitely be making a purchase.
