An option you have is to use IPv6 with DA and not IPv4 and still have the PAC file in place so it look up an IPv4 as there will be no matching IP for this on DA then it will go direct. (been years since I last used DA) PAC function FindProxyForURL(url, host) { // If the hostname matches, send direct. if (dnsDomainIs(host, "intranet.domain.com") || shExpMatch(host, "(*.abcdomain.com|abcdomain.com)")) return "DIRECT"; // If the protocol or URL matches, send direct. if (url.substring(0, 4)=="ftp:" || shExpMatch(url, "http://abcdomain.com/folder/*")) return "DIRECT"; // If the requested website is hosted within the internal network, send direct. if (isPlainHostName(host) || shExpMatch(host, "*.local") || isInNet(dnsResolve(host), "10.0.0.0", "255.0.0.0") || isInNet(dnsResolve(host), "172.16.0.0", "255.240.0.0") || isInNet(dnsResolve(host), "192.168.0.0", "255.255.0.0") || isInNet(dnsResolve(host), "127.0.0.0", "255.255.255.0")) return "DIRECT"; // If the IP address of the local machine is within a defined // subnet, send to a specific proxy. if (isInNet(myIpAddress(), "10.10.5.0", "255.255.255.0")) return "PROXY 1.2.3.4:8080"; // DEFAULT RULE: All other traffic, use below proxies, in fail-over order. return "PROXY 4.5.6.7:8080; PROXY 7.8.9.10:8080"; }

you can do a simple loop with :run copy souce dest ping -n 600 127.0.0.1 >nul goto run miss use of ping but it will work.

I dont see an issue of letting the staff from home go via the school if you have filtering and AV scanning in place at the school it just another step to stop them letting there kids use the laptop at home and surf sites they should not be going to, we all have a teacher that does that you might not know about it.

Looks like no TPM in the Bios whats the make of computer?

Also if you can get an ADSL line in for a failover for the SIP it in case your internet is off loner then needed so you can still make calls, and keep a hard line and get your sip to failover to it if you dont want an ADSL Failover. I used 3CX and VM the phone system and got some of the add-ons.

I have had this issue a lot with Windows 7 and Lenovo laptops and desktops. In the end, I cleared the TPM and run the BitLocker Wizard to fix the issue.
