LAN Manager 2.2c Setup Does Not Allow DNR Address To Be Blank
Last reviewed: December 14, 1994

Article ID: Q123753

The information in this article applies to:


 * Microsoft Windows NT Server version 3.5
 * Microsoft LAN Manager version 2.2

SYMPTOMS
The TCP/IP protocol for LAN Manager 2.2c client that is shipped with Windows NT Server version 3.5 is enabled for Dynamic Host Configuration Protocol (DHCP), which allows a user to use the DHCP server to provide IP configuration data. This data includes the IP address, subnet mask, default gateway, Windows Internet Name Service (WINS) server IP address, Domain Name Resolution (DNR) IP address and Domain Name Suffix. If a user enables the DHCP configuration, the user should have the option to leave these entries blank. However, the Setup program for LAN Manager version 2.2c does not allow the DNR IP address and the Domain Name Suffix entries to be blank.

WORKAROUND
To work around this problem, follow these steps:


 * 1) Enter an IP address and Domain Name Suffix entry in the LAN Manager version 2.2c Setup program.
 * 2) Remove the values assigned to NameServer0, Nameserver1 and Domain entries in the TCPUTILS.INI file. Doing this allows the DNR module to load and use the information provided by the DHCP server.

STATUS
Microsoft has confirmed this to be a problem in LAN Manager version 2.2c. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
