I'm configuring SBS 2008 SP2 which is a single AD DNS to work with XPP SP3. The XP gets event error 1053 and 1054 after login, and there are group policy issue can't be applied to XP. XP gets dynamic ip correctly from DHCP of SBS, but Ipconfig/all doesn't show DNS and Default Gateway. I'm unsure if there's problem with the DNS server settings. Could anyone pls help?
