DOCUMENT:Q170316 10-AUG-2001 [crossnet] TITLE :Client Receives Error When Resolving Fully Qualified Domain Name PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER:winnt:1.0,3.5,3.51,4.0 OPER/SYS: KEYWORDS:kbinterop kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Attempts to resolve fully qualified domain names (FQDN) for your internal domain fail, resulting in error messages from your applications similar to the following: Host not found -or- Bad IP Address . CAUSE ===== The Microsoft Proxy Client may cause this problem if it is incorrectly configured. RESOLUTION ========== Edit the Mspclnt.ini file to add your internal domain suffixes as described in the Microsoft Proxy Client documentation using the LocalDomains entry. Using a text editor, open the Mspclnt.ini file and add or edit the LocalDomains entry in the [Common] section and set it equal to any domain suffixes that exist on your internal network. For example: [Common] LocalDomains = test.lab.com, lab.com MORE INFORMATION ================ The Microsoft Proxy Client will, by default, forward all FQDN name queries to the proxy server on your network. The proxy server then forwards these queries to its DNS server, which is most likely on the Internet. Unless your internal domain name(s) are registered on the Internet, the name resolution for the internal domain name will fail when processed by an external DNS.
