I have some clients must use internal proxy to access to some websites (security rules).
When they use DirectAccess client outside corporate network, they have problem to access to those websites.

You need to edit Name Resolution Policy Table (NRPT) on DirectAccess (DA) server by using powershell cmdlet.
Add-DAClientDNSConfiguration -DnsSuffix ‘www.mywebsite.com’ –proxyserver ‘myproxy.mydomain.com:8080’
Powershell cmdlet will edit GPO DirectAccess policy, so after successfully run cmdlet you need to run GPUPDATE /FORCE on Windows 8 client to get effect immediatly.
