A bit stumped and wondering if you can help?
1 x SBS 2003 server, no ISA, 1 x NIC, fully patched, working fine on ISP ABC (8Mb ADSL)
PPTP VPN passthrough, routing remote access, exchange, OWA, RPC over HTTP, IIS all working fine
Migrating to ISP XYZ (FTTC)
so disconnect the existing router /firewall pointing to ISP ABC (8Mb ADSL) and switch it off
Attach the server via the switch to the new router firewall connected to the new ISP XYZ (FTTC).
The new router firewall has the same internal IP address as the previous router firewall but of course with the new ISP settings. ALL NAT and PAT configured (in fact its the same model of router / firewall as the previous one)
We update DNS and external mail host IP addresses.
run the ciecw and fails on firewall
The end result is that internet is coming through fine on the LAN and emails GOING OUT (as its using the SBS connector) but emails coming in, VPN, HTTP over RPC is not working.
We see that after the CIECW, IIS is not happy with all the default web sites stopped and I have to reboot the server.
Not sure where the clues are in the icw txt file attached.
I then revert back to the old ISP (fortunately both running in tandem) and run the CIECW again and again it fails on firewall and IIS stops and a reboot but fortunately all services kick in.
We have tred then again to move to the new ISP but the same issue and I believe it is to do with the server.
Please don't suggest migrating to SBS 2008/11/12 as once this server commnicates on the new ISP we're moving the whole lot to a hosted server environment and office 365
Any pointers would be appreciated.
