SYMPTOMS
When a Windows NT version 3.5 or 3.51 Remote Access Service (RAS) server
uses dynamic host configuration protocol (DHCP) servers to assign remote
TCP/IP client addresses, the range of IP addresses that the RAS server
receives is cached in the registry. If you reconfigure the DHCP server to
allocate and provide IP addresses from a different address pool, the RAS
server still assigns IP addresses from the original RAS client address
pool.
CAUSE
The RAS Server does not query the DHCP server for new IP addresses until
the original address leases (cached in the Registry) expire.
RESOLUTION
To force the RAS server to use the new IP addresses provided by the
DHCP server:
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
- Run Registry Editor (REGEDT32.EXE).
- From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters\Ip
- Remove the DhcpAddresses subkey.
- Close Registry Editor.
- Shutdown and restart Windows NT.
