Windows NT Systems Running RAS May Exhaust Available DHCP Leases (153161)
The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q153161 SYMPTOMS
A RAS service configured to use dynamic host configuration protocol (DHCP)
to allocate IP addresses for dial-up clients may acquire more IP address
leases than needed, thereby depleting available addresses.
The leased addresses are indicated by a telephone icon in the Active Leases
window of DHCP Manager.
This problem can occur when portable computer users on the network who have
installed RAS and configured it for dialing out and receiving calls start
their systems on and off the network.
CAUSE
During initialization, the RAS service acquires new leases because it fails
to read information regarding previously acquired leases. The previously
leased addresses, now orphaned, will only be returned to the pool of
available addresses when their leases expire.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the
