Arrgh one last Exchange / Outlook question

[m4cc45]

Network:

192.168.0.1 Outlook / DNS server

Clients:

192.168.0.20 onwards

If I put a static IP in it works fine.

If I change it to DHCP the Internet works fine and the majority of clients access Outlook fine.

However for some reason it doesn't work fine on all of them and if I change them to a static it does work.

Any ideas? I've flush'd DNS.

This is going to sound stupid but.....Are you sure you have set up DHCP correctly?

When you switch to DHCP can you do an "nslookup" and resolve your outlook (although I assume you mean Exchange) server by name and IP?

When on DHCP can the client PC's ping the server?

What have you got set as the Default Gateway/DNS Server adress and are they all on the same subnet when under DHCP?

damn i'm rambling now, i'll shut up........

Post an unedited ipconfig/all from both a client using dhcp, and one working with a static IP.
