Having to manually specify DNS server on each PC - WinSvr 2008 domain

In our LAN, unless I manually specify the following settings on each workstation, users cannot login/access share drives.

Primary DNS: 192.168.0.49 (W2K8 Domain Controller)
Alternative DNS: 8.8.8.8

If I only specify the primary DNS to point to 192.168.0.49, then share drives are accessible however no internet access is available. So I point the alternative to Google's DNS.

Of-course the above practice is not recommended and causes issues with users taking their laptops home.

Why does this happen? Why cant the workstations talk to the DNS server on the W2K8 DC?

Please help

You need to:
- Enable DNS forwarders in your local DNS

- Specify the DNS list to use in DHCP configuration (DHCP option 6 "DNS servers", not DHCP option 5 "name servers")

setup dhcp and add dns as the 2008 server

Or push them out with group policy
Computer Configuration | Administrative Templates | Network | DNS Client

Setup a forwarder to point to the 8.8.8.8 in the server dns

DHCP and DNS are setup in 2008 server already.

but not all client computers are joined to the domain. some are visitors who come in with laptops, connect to the office wi-fi and then try to browse the internet/access specific files on a share folder.

i believe gpo will not work unless the pc is joined to the domain.

-Setup your Scope in DHCP to provide internal DNS server in Scope Options. (Option 006)
-In your DNS Server select proprieties, then in forwarders, point to external dns.
-restart DNS Server Service on dns service
-restart Workstations to update new Scope options or IPconfig /Release and ipconfig /renew

I think is solve
right now with 006 option pointing to 127.0.0.1, you have all workstations query themselves for all DNS Request.
