Networks
I have multiple subnets at my office and I am trying to telnet to the exchange server. If I use the subnet that the exchange server is on then I can connect. If I use a machine on a different subnet then I cannot connect to exchange in this way.
What do I need to be looking for to resolve this issue?

This is not an option as it has been working previously up until 2 weeks ago.

You have one of the following scenarios:
1. You have one router which interconnects all subnets, and another router to connect to Internet. Your default gateway on the exchange server set to "internet" router.
Problem: Your exchange server does not know how to access another subnets, it sends this traffic to default gateway, and your default gateway does not know where to send traffic as well.
Solution: You should either add correct routing to your exchange server for all remote subnets, or add routing to your "internet router" so it will forward traffic to appropriate router.
2. You have one router or layer 3 switch, which interconnects all subnets, and connects to the Internet. And this router has access list(s), which prevent your connectivity. As an variant you may have firewall instead of router.
If you have more questions, just e-mail me.
