Hi there Muhammad,

Yes you can. You need to set the dhcp server to send out "option 252" with the address of your web proxy.

Re: WPAD through Cisco DHCP

Hello again,

Can you confirm if the switch is sending out the dhcp option? A simple sniff should decide that. If it is sending it out, then you need to have a look if your syntax is correct. I've just had a quick look here http://www.microsoft.com/technet/prodtechnol/isa/2004/help/SRSP1_H_Create252.mspx?mfr=true and it says that the syntax should be "http://ipaddress:port/wpad.dat". If you've not put in the port option, then it will go to port 80, which the server may not be listening on.
