Hi,

I have a problem with dns client on a computer running Ms
Windows 2000 SP4

The problem is that dnschace crashes randomly and it can't
resolve any name, throwing the "Uknown host" error.

When I restart dnscache with these commands,

C:\net stop dnscache
C:\net start dnscache

dnscache resolves correctly again.

I have tried to flush all the dns cache entries
with "ipconfig /flushdns", but it doesn't works.

Lastly, I entered to registry and the parameters of
dnscache are these: (and I think that are correct, isn't
it?)

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnsca
che\Parameters]
"NegativeCacheTime"=dword:0000012c
"NegativeSOACacheTime"=dword:00000078
"NetFailureCacheTime"=dword:0000001e
"AdapterTimeoutCacheTime"=dword:00000078
"CacheHashTableSize"=dword:000000d3
"CacheHashTableBucketSize"=dword:0000000a
"NetFailureErrorPopupLimit"=dword:00000000
"MaxCacheEntryTtlLimit"=dword:00015180
"MaxSOACacheEntryTtlLimit"=dword:0000012c


So, to solve this problem I restart the client when it
crashes. But I would like to find the reason why is
happening this. And I would be very pleased to find a
definitively solution for this problem, due to it crashes
really often.



Thanks,

Gerard Forns

Can you post an ipconfig /all from the client please? That can give us a
start in diagnosing.
Thanks

You'll need to provide the register dump and what is recorded in the event
log.

Then you, too, can provide the register dump and what is recorded in the event
log.
