How Can I Use Wireshark To Troubleshoot a LAN connectivity issue

asked 2019-05-30 11:36:04 +0000

I have a network with 5 pc's. Randomly, I log in (remotely) to the network and find that all mapped drives are not connected. PC 1 is my backoffice. PC 2 - 5 are workstations (Workgroup, not domain). PC 2 - 5 are all mapped to PC-1. They are password protected as well. Today PC 2 was connected but PC 1 and PC 5 were disconnected.
How can I use Wireshark to troubleshoot this problem in the future. This happens frequently enough and I want to get my arms around the issue.

Thanks in advance for any assistance provided.

Come on over to SharkFest and learn from the pro's. :) In all fairness, try to assess this from the top down. See what the logs on the Windows machines tell you, then work your way from there. From the other end you may want to look _very_ carefully at your NICs, cabling, connectors, sockets, switches and what other network gear you have. Intermittent problems here may also cause problems higher up the network stack. In short, with such little information there's little to give in guidance. Wireshark, being a power tool for power users, may not be the right instrument for this.
