MS exchange server - changing ISP
Hello,
I'm trying to switch ISP, and I'm wondering what setting do I need to change.
I have exchange server here but I'm using domain service with Network solutions.
Network solutions is redirecting emails to my local exchange server.
I didn't set up exchange server nor Network solutions and wondering what needs to be change if I change ISP. I will have different IP address by using different ISP.
My guess is to change only IP address with Network solutions, but I would like to make sure before I struggle when I do it. I can't stop email service all day until I figure it out.
Do I need to do anything with Exchange server?
Thank you

MX record and any ISP DNS entries you have also the new ISP DNS server needs to have your Exchange server IP information ...... if there is any Firewall that receives information from ISP and then delivers to the Exchange u need toc orrect that too ........ Check SMTP virtual server or SMTP connector should not have smarthost ...... also remove if you have it under forwarders in DNS forwardslookup zone

1st attempt failed. I wanted to test more, but ran out of time.
I switched to Comcast(new isp) and I couldn't even connect to internet.
I tested with different small switch (not connect to server) and all computer could use internet.
New switch works fine with current ISP (Qwest).
Here is my set up.
modem ---- switch ----- windows server 2003, clients PCs (server and client PCs are connected same switch)
I didn't reboot server and I'm not sure what assigns ip address for each machine.
My guess will be to reboot server and switch, but I haven't tried yet..
Any suggestion??

2nd attempt - after rebooting server & switch, internet worked fine.
Exchange server failed. I ran out of time again and couldn't wait for long time.
I may just have to wait until exchange configures client setting....
I will try again next week....

Hi,
I have listened some issues like this with Comcast before! but anyways if you have forwarded the ports correctly as I defined in first post then restarted the router; there should not be any issue, if no firewall is blocking it.

Third attempt-
Comcast cable modem had DHCP enabled and conflicted with Windows server 2003 (?)
I turned it off, but I couldn't get some computers to go online.
I called Comcast and told me to change default gateway.
Do you know where to enter default gateway in windows server 2003?

Only place I can think of is Internet Protocol (TCP / IP) Properties.
Anywhere else?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
All you need to do is the change the IP address which you get from your new ISP into your DNS MX record, also ask your ISP to create RDNS record to match your mail server.
