I have a SBS2008 network behind a CISCO PIX 501with a zyxel router.. Pretty standard stuff.. The setup has been in use for years on a SBS2003 before this one, which, incidentally, was a clean install with just the data copied over.
Everything was working absolutely beautifully until yesterday when I was remotely linkje in and all pc's and server disappeared from my screen on LogMeIn.
after some checking with ISP etc,I found that the router had died. I replaced it with the same make , but different model.. configured exactly the same, plugged it in and all appeared to be OK.. I had internet access (on the server) and email on Exchange was working fine, clients were picking up mail and navigating the server without any problem.. BUT none of the client boxes could browse the internet. (They were all working beforehand!!)
I have looked for errors in the logs and found nothing that might indicate a cause for this behaviour.. Server can ping clients and vice versa..
I am lost! help please!! Nb. I have got forwarders configured in DNS and ipconfig gives the desired result on the clients DNS points to the server and the default gateway is the PIX
