Cannot find server or DNS Error

Hi all.

A familiar subject I'm sure, I'm getting "Cannot find server or DNS
Error" when trying to access any of the websites on one of my IIS
servers (2K3+SP1, IIS6). This happens randomly, and not very often,
but the only way I have found to resolve the issue is to reboot the
server - not even restarting IIS (iisreset) or restarting the App
Pools will resolve it.

Any ideas where I should start to try and figure this out? The event
log shows nothing that might indicate a problem with IIS.

I've reallly hit a brick wall with this one.

Hi

Some things to check (in order):

a) httperr.log logfile, in case http.sys is dropping the connections
b) verify that other services on the machine are still accepting connections
(it may be that it isn't just http.sys that is dropping connections - maybe
nothing is getting through. In which case it may be a driver issue or
something)
c) get a network packet capture, in case some other weird issue is happening
(e.g. name resolution or something)

Cheers
Ken
