|This is a small business network issue specifically with some of the connected PCs. Last year they had their Win 2003 server fail (drive fail-over problem with OS) and it had to be re-installed with Win 2003R2 server (per Microsoft Techs). Since then 2 of their 5 connected PCs have had this problem of freeze up ~4:30 - 5:00; not every day, but most. Now there is a 3rd PC being affected.|
- A proactive reboot can often preempt the happening.
- The "freeze up" seems to be from a disconnect of network drives during the passing of data. There are homegrown databases in use.
- Other PC's using the same local 10/100 switch and SOHO router do not exhibit the problem.
- I thought I might have fixed the problem when I found that all of these PCs and the server all still had the time server set to time.microsoft.com (which is no longer supported) and changed to a government time server. This stopped some random freeze ups earlier in the day which had confused the 4:30 issue, but did not solve both.
I have obviously combed through many log files on both local PCs and the server, but have yet to find a cause.
