DHCP shows ip addresses with RAS as the ID

Hi all,
1- 2000 server with AD and DHCP running
1-2003 server with AD and DHCP running
When I look at my DHCP leases some of the ips show the server name having 6
or more ips assigned to it as RAS.
Why would the server be using more than one ip in dhcp?
I also have a regular workstation listed with RAS as the ID.
Thanks in advance for any help or explaination on this.
Sher

When a remote user connects to the RAS server, it gets its IP config from
the RAS server, not directly from DHCP. If the RAS server is configured to
use DHCP it will lease a batch of IP addresses from your DHCP server. It
will use one of these for its internal interface (the end point for the
dialup or VPN connection) and allocate one to each remote user.

If a workstation is leasing an extra IP for RAS it must have incoming
connections enabled. It needs an extra IP for its client as above.

Hi Bill,
Thanks for the info. I do not have remote users dialing in or vpn setup.
The only thing I have running is auto antivirus updates running.
I have users mapped to different servers within. The workstation should not
have any remote connections. If the remote desktop was on would that be a
cause on the workstation? Would the antivirus be using RAS?
Thanks again,
Sherry

Hey again Bill,
When you say "incoming connections enabled" where is that located? I looked
under services but not sure?
Thanks again,
Sher

If a server has leased extra IPs from DHCP for RAS, this server is
enabled for remote access (or has been at some time). If it is not currently
enabled, the leases will expire.

That depends on what OS is running in the workstation. Search the help
files for "incoming connection".
