XP client eventually loses network connection

Windows XP 32 bit
Myself: I work an IT on-site help/service desk (2nd level). Client: HP Workstation running WinXP Pro SP3 x86 in a manufacturing role at a test station on an assembly line. Situation: All the computers in this division run under a local user account, logged in to the computer itself. They are joined to the domain when we configure them, but are almost never logged in to the domain by the user's or supervisors. Problem: We've found that over time these computers and workstations lose their connection to the network resources; it doesn't get updates, we can't PING it, can't remote into it, etc. The "fix" is to re-join it to the domain. Question: What is the technical reason(s) why they drop off? And what can be done to prevent this in the future?

    Do the event logs show anything useful? What is the time range the systems seem to stay connected in? -- Tom

    Tom, Nothing of note in the event logs. We've got several dozen of these clients at 3-4 areas of the plant. We should have tracked this better; it's been going on for over a year and I've been here about 8 months. They just 'drop-off' one by one. Because of their function, we don't really have time to dig into the logs and traces to figure out what's happening. The 'rule' is to get 'em back on-line. Lately the supervisor of those areas has asked us to find the reason so it doesn't happen in the future. My thinking is that there must be something about WinXP's networking that lets it 'drop off' after a period of time of NOT being logged into the domain (remember, each is logged into with a local account).

    Not being able to ping these devices seems particularly odd if the devices are still active. If they have shut down, it'd be different. Is the problem only visible in networking? Or is there also something like an actual shutdown that happens? -- Tom

    No shutdown. Just that they can't be reached via PING or remote (the area supervisor uses Dameware to remote in and check on his computers).

    An idea hit me ... what if it's not 'dropping off' but the DNS TTL expires? I'm certainly no expert on DNS, but maybe the problem is that - since it's not logged into the domain, could the DNS record on the server(s) expire? This gave me the start of the thought process: http://support.microsoft.com/kb/318803

    That's kind of related to the type of thing I was thinking. But that is related more to the WinXP system trying to ping a remote host name rather than trying to ping the WinXP system FROM the remote host. How is your failing ping done? Is it by host name or by IP address? When the ping fails, can you have someone look at the WinXP system to verify the IP address? If the address is used, does the ping fail? What does tracert show for both the address and the host name? -- Tom
