TCP/IP help request

A few months ago the institution I work for switched from static to 
dynamic IP addressing. As an OS/2 user I was slightly concerned about 
the change, but it proved to be painless, a small adjustment to the 
TCP/IP setup and I was in business – until this week. Over the weekend 
our network administration made some “minor adjustments” to the network 
setup, as a result of which I can no longer go online. Windows still 
gets a connection and even XP running under Virtual PC for OS/2 connects 
if I use the Virtual Switch network option. The latter suggests that I 
ought also to be able to connect OS/2, the problem is I do not know 
where to put the relevant settings in the TCP/IP configuration notebook.

Windows reports the following:

Address type – assigned by DHCP

IP address:  10.x.y.z
Subnet mask:  255.255.255.0
Default gateway: 10.x.y.z
DHCP server: 10.0.x.x
DNS servers: 	10.0.x.x
		10.0.x.y

My question is: under which tabs on the TCP/IP configuration notebook do 
I enter the Default gateway and DHCP server (and also perhaps the DNS 
servers)?

One more question. In my quest for a connection I tried crossing off the 
“Also using DDNS” box on the “Network” page of the TCP/IP Config. 
Notebook. This didn't help, so I removed the cross but the “DDNS Client 
Configuration” window still appears at the end of system boot-up. How 
can I stop this happening.

Any help would be gratefully appreciated – I am already tired of having 
to have Virtual PC running in order to access my email and the internet.

When using DHCP OS/2 will find the DHCP server automatically. The DHCP 
server wil give you the other required information.

Tab Network : Configure LAN interdace 0 with: Automatically using DHCP.

Tab Routing: remove default route (DHCP will provide the router).

Tab Host Names: Remove the entries for Name Server Address  (DHCP will 
give them to OS/2)

I don't know if you need to remove this Computers Host Name (as DHCP 
server will also give you a hostname).
You better first Keep the domain (should be the same as the Windows XP 
domain).

Under hosts keep localhost (and remove old enties or better deactivate 
Look through Hosts list ... as other IP's also wil be dynamically set).

Check startup folder, then remove it if present.  I accidentally did 
this recently with exactly the same results.

Thanks for the detailed advice, Sjoerd. Amazingly, when I got to my 
office this morning OS/2 immediately found the DHCP server using the 
settings that worked until a few days ago, so I'm more baffled than ever 
as to what is going on! Nevertheless, I went through the TCP/IP settings 
and set them up as you suggest. Today (at least) everything looks fine.

Regards,

Thanks, Barbara, that was all that was needed (why didn't I think of it 
myself?)
