DOCUMENT:Q200211 10-AUG-2001 [crossnet] TITLE :DUN Clients Do Not Receive DNS Domain Name over RAS/RRAS PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER:WINDOWS:95,98; winnt:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows 98 - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== RAS or DUN clients are unable to resolve friendly host names. The user must define/use the fully qualified domain name (FQDN) of the resource. CAUSE ===== The client does not have the domain name configured in its TCP/IP properties. RAS or RRAS use Point to Point Protocol (PPP) Internet Protocol Control Protocol (IPCP), which is defined in RFC (Request for Comments) 1877 to provide name server (DNS server) and NetBIOS name server (NBNS) or WINS server IP addresses to the RAS client. RAS or RRAS do not support DHCP forwarding. Additionally, PPP-IPCP does not support this either. When an RAS/RRAS server is configured to either use DHCP or a static pool for addresses, it follows the information found in the following article in the Microsoft Knowledge Base: Q160699 Understanding DHCP IP Address Assignment for RAS Clients Only the IP address of the primary and secondary DNS and/or NBNS WINS is negotiated with the PPP client. MORE INFORMATION ================ Future releases of Windows server operating systems will be able to pass DNS domain names to RAS clients through a DHCP inform packet after the PPP and IPCP have converged. Additional information will be available for this procedure upon the next release of Windows server.
