Hi Marrow,
Windows Server 2003 Standard allows 1000 concurrent VPN connections.
http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodt
echnol/windowsserver2003/proddocs/entserver/sag_vpn_us26.asp
Note
* On Windows Server 2003, Web Edition, and Windows Server 2003,
Standard Edition, you can create up to 1,000 Point-to-Point Tunneling
Protocol (PPTP) ports, and you can create up to 1,000 Layer Two
Tunneling Protocol (L2TP) ports. However, Windows Server 2003, Web
Edition, can accept only one virtual private network (VPN) connection at
a time. For more information about feature availability on Windows
Server 2003, Web Edition, see Overview of Windows Server 2003, Web
Edition
<http://www.microsoft.com/technet/prodtechnol/windowsserver2003/proddocs
/entserver/Web_Server_overview.asp> . Windows Server 2003, Standard
Edition, can accept up to 1,000 concurrent VPN connections. If 1,000 VPN
clients are connected, further connection attempts are denied until the
number of connections falls below 1,000.
HTH,
Tom

the VPN solution is just for email only. It seems that I don't
need in install ISA Server 2000 on Windows 2003 if it has the hard code
limited like this. I will expect 2000+ connection on my exchange server.
any suggestion ?
Very best regards,
Marrow Yung.

Hi Marrow,
It depends on what the users will do while connected.
Most VPN connections site idle, so they're not using much in terms of
processor cycles. If your users are transferring DVD images of their
favorite TV shows, then just one or two can be enough to bring your
server to a grinding almost halt. The thing about number of users is are
there hard coded limits to the number of accounts that are allowed to
VPN. Win2k doesn't have a hard coded limit, and Win2003 has a limit of
1000. Do you expect 1000 concurrent connections?
HTH,
Tom

I am looking for a VPN unlimited connection solution, I
see that all the VPN broadband router can only support maximum 70 VPN
Connections in the router level. However, I need the unlimited one for
my own company. What I am thinking is, I buy a Intel 10/100 Pro S Server
Adapter , which can support hardware IPSec in the NIC card itself( the
spec. in intel says that, that's why it is Server NIC , not desktop
NIC), then I use the VPN function in the ISA Server 2000 to create VPN
connection for all of my client. In the router level I will only let the
router enable the VPN bypass function , which is a common function in
all router in Hong Kong.
What do you think about my VPN unlimited solution? The
pricing of this combination will only cost 100-200 more Hong Kong dollar
when compare with using VPN router. Which is very good if I need more
than 70 VPN connections.
the shop keeper tell me it is impossible to have
unlimited VPN connection (I think he mean in the router level), he say
even it can, the bandwidth for 70+ VPN connection can't handled by
broadband connection. Is that true ? I will have a broadband connection
of 10Mbps upstream 10Mbps downstream. It still not enough ? I am not
going to assume they all connnect at the same time (through you can say
why I don't use VPN router if I don't assume it will handle all at the
same time, but I want to make it unlimited in the lowest price, the
hightest price is I link up all VPN router to make it support more than
70 VPN Connections if one VPN router is over limited).
Very best regards,
Marrow Yung.
