Hello, I need to monitor the system times on a bunch of Windows hosts from a Linux machine. For that I use "net -I 192.168.xxx.yyy time." For one of the 20 or so hosts, this command has begun to return the error: "Protocol negotiation failed: ERRDOS:ERRnomem." It used to work, maybe somebody did something on that machine, it stopped working. The Linux system is a RHEL7 host running Samba 4.10.16. Now I'm in the process of migrating to an RHEL8 server running Samba 4.16.4. The host that's been giving me trouble on the RHEL7 box responds fine on this machine; however, half a dozen of the other hosts time out with the message: "Protocol negotiation failed: NT_STATUS_IO_TIMEOUT" The debug flag doesn't do anything for me, either. On both Linux boxes I ran "net time" on a working and a non-working remote, and the diff comes up empty except for the IP addresses and the error message (see below). Any hints? Or alternative methods for querying the system times wihtout having to make changes to the Windows boxes? Of course I'm also fighting a fight to have the Windows machines synchronize their clocks to an accurate time server. Currently I seem to be losing both battles. Thanks robert ~$ net -d 9 -I 192.168.232.88 time > t88 2>&1 ~$ net -d 9 -I 192.168.232.42 time > t42 2>&1 ~$ diff t88 t42 151c151 < Connecting to 192.168.232.88 at port 445 ---> Connecting to 192.168.232.42 at port 445171,172c171,172 < Protocol negotiation failed: ERRDOS:ERRnomem < return code = -1 ---> return code = 0 > Wed Aug 16 15:25:50 2023~$
