My macbook pro connects to some windows machines but not all
Hello,
After upgrading my Macbook Pro from High Sierra to Mojave (10.14.3), I lost connectivity to some windows machines. I can connect to some Windows computers, but not all. From the Finder, I use Go->Connect to Server, smb://<hostname>/<directory>, which was working prior to the upgrade. All machines are in the same workgroup, network environment hasn't changed. I can ping all the machines in question. Any help is appreciated. Thanks.
