My company has store support representatives all over the United States that use normal means for High Speed internet, whether it be cable, DSL, satellite. They connect to our corporate intranet through a web based VPN client called F5 Firepass. Once connected through firepass, they are able to use Outlook 2003 and browse local intranet corporate webpages.
There is however a catch. If there is a DNS suffix placed inside Advanced TCP/IP settings for ?The Local Area Connection? under the DNS tab it won?t work and simple fire back a page cannot be displayed. All of our remote employees are issued company supplied routers (Net gear FM114P and FWG114P) and the DNS suffix is still forced into the settings. Sometimes hotels they stay at pushes a DNS suffix into the setting.
The solution we have is to go to the DNS tab inside of Advanced TCP/IP Settings and select the bullet ?Append primary and connection specified DNS suffixes? as well as the checkbox ?Append parent suffixes of the primary DNS suffix?.
Once the DNS Suffix is flushed, our intranet web pages work. Sometimes for weeks we won?t have to deal with the DNS suffix, for one employee in particular it gets pushed into her settings every hour.
I guess my questions, is there a way to we can prevent any DNS suffixes from being forced into our settings? Could a bat file be written that automatically flushes DNS suffixes?
This has only recently become such a big pain with one of our remote employee?s who has the Charter Communications internet provider. They have a DNS Suffix ?gbcglobal.net? that creates there own ?page cannot be displayed? page. It?s a lame attempt to profit off of address mistypes; however it proves to be a bigger nuisance for our employees.
All our laptops are Windows XP based machines running Sp2. Internet is high speed, provided by cable or dsl and through a wireless router. At corporate we using DHCP to hand out DNS servers and IP address (but no DNS Suffix).
