IPCONFIG Does Not Display Domain Name if Assigned Via DHCP

• Microsoft TCP/IP-32 for Windows for Workgroups versions 3.11, 3.11a, and 3.11b
• Microsoft Windows for Workgroups version 3.11

SYMPTOMS

The IPCONFIG.EXE utility included with Microsoft TCP/IP-32 for Windows for Workgroups 3.11 does not display the fully qualified domain name (FQDN) of the host computer if the domain name is assigned through DHCP. If the domain name is assigned manually, IPCONFIG correctly reports the FQDN.

The version of IPCONFIG supplied with Windows NT does report the domain name.

Sample output from IPCONFIG when run on Windows for Workgroups 3.11 DHCP client:

   Host Name . . . . . . . . . : ENG-LAB041 (should be
                                 ENG-LAB041.NETLAB.DOM in this example)
   DNS Servers . . . . . . . . : 157.55.136.218
                                 157.55.136.219
                                 157.55.136.220
   Node Type . . . . . . . . . : Mixed
   NetBIOS Scope ID. . . . . . :
   IP Routing Enabled. . . . . : No
   WINS Proxy Enabled. . . . . : No
   NetBIOS Resolution uses DNS : No

CAUSE

IPCONFIG.EXE does not read the domain name from the DHCP.BIN file. The domain name is read only from SYSTEM.INI.

STATUS

Microsoft has confirmed this to be a problem in TCP/IP-32 for Windows for Workgroups versions 3.11, 3.11a, and 3.11b. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
