In researching a different problem, I noticed in the SLDataMiner log the following entries repeated every minute since the last DMA restart (NOTE: I obfuscated the IP addresses to be safe):

2022/06/25 16:05:27.142|SLDataMiner.exe 10.2.2143.9720|7772|14544|CHardware::Init()|INF|-1|Add IP 100.x.x.140 (255.255.255.0) on (0) (AdapterCount = 0)
2022/06/25 16:05:27.142|SLDataMiner.exe 10.2.2143.9720|7772|14544|CHardware::Init()|INF|-1|Index for adding is 3

The DMS contains 3 FO pairs running DM 10.2.0.0-11774-CU3 and all three have similar messages. That said, one of them also shows an ERR message about the Gratuitous ARP message failing to send:

2022/06/23 16:15:35.227|SLDataMiner.exe 10.2.2143.9720|5620|28856|CHardware::AddIPAddress()|ERR|-1|Failed to send out Gratuitous ARP message for added IP address 100.x.x.171. WinPcap is probably not installed on the system. (0xc0000135; C:\Skyline DataMiner\Tools\SLSendGARP.exe 100.x.x.171 -if "rpcap://\Device\NPF_{60CBD3A3-D42B-4957-98CE-1189B3ED5861}")

Two questions:

1. Is the issue that is generating the ARP message also causing the "Add IP" entries on the other DMAs or are the two things unrelated?
2. Does the installation of WinPcap (or I suppose Npcap these days) require a DM restart?

Thanks!
