----------------------------------------------------------------------
The information in this article applies to:

 - Microsoft LAN Manager version 2.2c
----------------------------------------------------------------------

SYMPTOMS
========
On a LAN Manager version 2.2c MS-DOS client using TCP/IP, if Setup is used
to disable DHCP and then later to reenable it, the reenable fails. The
client continues to use the manually-configured IP address.

CAUSE
=====
When DHCP is disabled using Setup, the following entry is added to the
PROTOCOL.INI file:

   DISABLEDHCP = 1

Later, if Setup is used to reenable DHCP, it fails to remove this line, or
change it to DISABLEDHCP=0.

WORKAROUND
==========
Manually edit the PROTOCOL.INI file by deleting the line containing
DISABLEDHCP = 1.

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.
