New Network Problem after installing Windows Service Pack 1 Update
I had this problem on-and-off for a very long time, first with XP pro, and now with win7 !?!
The problem is that if connecting the RED cable (see diagram) the server will strangely eventually find its way to connect through the switch to the internet instead only directly through the gateway doing this: switch > gateway > modem to the
internet, instead modem > internet.
This is not good as it bypasses the servers DNS setup and brings down the name resolutions for requests from PC1 (instead of going PC1 > switch > gateway > modem > internet > modem > server, it will eventually find its way to go PC1 >
switch > server and back the same way.)
I would like to limit the RED cable only to be used for file sharing and backups, so I have direct access to the server from PC1, 2 and 3 (PC1 > switch > server)
This very same setup worked for many month using Win7, but for one week now, after this last OS update Service Pack 1 I have this problem again.
