Throughout the day, my 3G modem will sometimes disconnect and reconnect instantaneously. If I happen to request a webpage at the exact moment the modem disconnects, Windows will cache the failed query and I can't visit that page without executing ipconfig /flushdns
.
I have to do this about 20 times a day and it's extremely annoying. I edited the registry to disable caching failed DNS queries:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache\Parameters
Name: NegativeCacheTime
Value: 0 (DWORD)
This seemed to work for a few days, but now Windows is caching them again. I've checked the registry and the value of NegativeCacheTime
has not changed.
What's going on here?
Seems like you're trying to turn on a flashlight with your nose. Fix the 3G modem is what I would do. – digitxp – 2010-09-15T01:53:39.840
There's nothing I can do about the 3G modem. It's a side effect of using mobile broadband in a rural area. Unfortunately, it's the only broadband I have access to. The reconnect is usually unnoticeable anyway, aside from the problem I outlined here, which is a Windows issue. – David Brown – 2010-09-15T13:42:52.103
