I created an easy patch for this bug in a RegEdit file. To use this fix, you need to put the text below into a text file called "dhcpfix.reg". Then double click on the file and select yes when the "Merge into registry" box comes up. After that, you should get a "Operation sucessful" box. Note that this was only tested on Windows 98 and Windows 98 SE. It may or may not work on Windows 95/Windows 2000/Windows XP.

DHCPFix.reg begins after this line:
-----------------------------------
REGEDIT4


"ReleaseLeaseOnShutdown"=dword:00000001


"FastReboot"=string:"0"
------------------------------------------
DHCPFix.reg ends before the previous line.
