Hi I have replaced my ISA 2000 server and now my servers cannot resolve internet DNS names<br />
<br />
My Client PC's work perfectly and all other Firewall functions are ok<br />
<br />
My servers can access the internet and resolve DNS through the web browser but I cannot ping<br />
or trace an internet dns from the command prompt ...<br />
<br />
Also my outgoing email server cannot resolve any dns to send email
