Default Gateway changing on Server 2k3

Hello

I have an SBS server and standard 2k3 server for RDP. SBS is 192.168.0.1,
rdp server is 192.168.0.2 both with 255.255.255.0

I set up RDP port forwarding on the ISA to direct all traffic to the 0.2
machine. I set the the default gateway to the 0.1 machine.

RDP works fine- for like 60 sec. then the connection gets dropped. when i
look, the default gateway is 192.168.1.254. even when the GW is hard coded
on the nic - it still changes. then i cant connect remotely. im not even
sure what that IP is from.

Any ideas?

thanks
JamesSF

Are you using the DHCP server here?
What ranges and settings are you using for the scope?

(There is also a DHCP-feature in the ICS which uses
the ranges you show above -- on 'server' it is better
to setup up your DHCP in the full product.)

If you hardcode the Default Gateway it will
NOT changing unless you connect as an RRAS
client or change it manually.

When connected as an RRAS (VPN or DIAL)
client the "temporary" connection default gateway
will override the manual one, but only DURING the
connection.

Even DHCP will not override the default gateway
on the SAME NIC (if you manual override this
setting on that NIC.)

yes - DHCP is on the 0.1 machine - but the server ips are static and the
scope is set to exclude first 10 IPs

hmm, but it is. RRAS is turned off on both servers - but we arent using a
VPN here - just RDP

still trying options.......

ok - fixed it - heres the answer for future reference

the DCHP server was handing out the wrong default gateway with an IP - not
sure how anyone was able to get the web on the LAN, but remote users were
getting an IP with a bad dafault gateway and it was dropping the connection

but, the default gateway on the 0.2 server was having its GW changed when a
client connected to it even though it had a static IP

kinda odd - but at least its working :-)

I wrote "RRAS CLIENT" since you said you were
seeing Default Gateway change -- that is the only
built in reason such will change without either the
DHCP server or manual settings changing.

Ok, you could have multiple Default Gateways
listed on the NIC, and the first was DOWN and
then it would USE the second one for a while.
