If a Windows for Workgroups dynamic host configuration protocol (DHCP)client has an active lease that is manually deleted on the DHCP server, andthe client attempts to renew its lease using IPCONFIG /RENEW or thestandard renewal process based on lease expiration, the following errormessage appears:
DHCP.386: This DHCP client was unable to obtain an IP network address from a DHCP server.
To resolve this problem, upgrade to Windows NT Workstation and Serverversion 4.0.
If you encounter this problem when you run IPCONFIG /RENEW on theclient machine, you can work around this problem by running IPCONFIG/RELEASE before running IPCONFIG /RENEW.
If this problem occurs during the normal lease renewal process, you muststop and restart the Microsoft DHCP Server service on the DHCP server toallow the client to receive a new IP address.
Microsoft has confirmed this to be a problem in Windows NT version3.5. This problem was corrected in Windows NT Workstation or Server version 4.0.
