Hello Experts ,

We have two sites connected with ISA site 2 site VPN with the same active directory

site 1 :
3 domain controllers - ISA server 2006
Site 2 :
2 domain controllers - ISA server 2006

Sometimes firewall client at site1 detect site 2 ISA server and vice verse and when we try to ping wpad it resolve the other site ISA server IP .

If we remove automatically detect proxy setting from internet explorer client successfully connect  to its local ISA server .

we need to know why clients sometimes detect the other site ISA server also how we can deny this ?

Thanks in advance for your support .

I have solved this issue but force client to use dhcp to discover wpad file
 navigate to :

HKEY_Current_User\Software\Microsoft\Windows\CurrentVersion\Internet Settings
Then add the following value:
DWORD: AutoProxyDetectType Set the value to 1 to force DHCP only.

Now we need to reload wpad  for Internet Explorer to detect changes by remove “automatically detect setting” and “use automatic configuration script” from connection tab at Internet options then close Internet Explorer and open it again then enable them again .

Also at cmd  type ipconfig/flushdns to clear DNS cache
