IPCONFIG Shows Leftover DHCP Parameters On Non-DHCP Clients

 Last reviewed: September 9, 1996
Article ID: Q125963
The information in this article applies to:
  • Microsoft TCP/IP-32 for Windows for Workgroups, version 3.11
  • Microsoft Windows for Workgroups version 3.11

SYMPTOMS

If you configure your TCP/IP-32 client to use DHCP and then re-configure it not to use DHCP, when you execute the command, "IPCONFIG /ALL", it will show old (DHCP supplied) values for certain parameters. Although, the client will ignore these values and use the local configuration, this may be confusing.

Parameters which may appear incorrectly in IPCONFIG include:

  • Primary WINS server
  • Secondary WINS server
  • Node Type

CAUSE

IPCONFIG is looking at values in the hidden file, DHCP.BIN, which is not updated when the client is switched from being DHCP-configured to manually configured.

WORKAROUND

To work around this problem, remove the hidden file, DHCP.BIN, found in the Windows directory.

STATUS

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