Unable to Ping

SBS2003 with 5 PCs - I cannot ping with IP address or Names although clients
can read directory on server. Up until yesterday DHCP was dishing out leases
and today, it didn't. Gave up in the end.

Any pointer as to where I could find info as to what could be wrong

What has changed? Is the DHCP server started on the SBS?

From any station, what is the ip address shown with ipconfig /all

If you type it this way:

ipconfig /all > c:\iptest.txt

you will get a text file in the root of C that you can open with notpad and
post back the contents.

SBS will disable DHCP if it sees another DHCP server on the network. Coupled
with the name resolution problem I'd suspect another DHCP server is giving
out leases with the wrong DNS options. Have you recently added a new router,
wireless access point, reset the router etc?

Yes, I did change the router because the last one packed up but settings are
exactly same and DHCP on router was turned off before being installed. DHCP
on SBS2003 is running but not giving out leases - because clients cannot see
the server.

If the stations are not getting IPs from the SBS DHCP they are not physically
connected or there is a process on the stations that prevents it. Not much
else it can be.

Verify that there is no "internet security" or other such stuff running on
the stations, and give one of them a static IP in the same range as the SBS
internal nic. You will not be required to reboot, but you can if you wish.
Now try to ping the server by ip and by name.

If you have not already done so, you might want to check your switch ports
if you have a managed switch or try a different switch if you have a basic
unmanaged switch. That is the sort of thing that will get me every time.

Ping results:
If 'ping name' then host not found
If 'ping IP' then request timed out
DHCP claims it is running.

Server address is 192.168.1.100 and with DHCP on the router 'disabled' ie
using DHCP on Server, clients get address '169.xx.xx.10 with Mask of
255.255.0.0.

I tried setting client at 192.168.1.112, 255.255.255.0 and DNS of
192.168.1.100 I cannot ping although I can see server in Windows Explorer.

Please post ipconfig /all from the server and from a client where you have
set a static IP.

Problem Solved. First of all thank everyone for all your help.

First problem was firewall. Then something weird with DHCP. It was leasing
out and then it was disconnecting. So, when I opened DHCP console it was
saying not connected. But when I clicked on Server underneath DHCP it said
'Running' and then clicking on DHCP it was Active and running and from here
everything worked as it should until reboot.

Googled 'DHCP not connected' and one of the responses suggested right
clicking on DHCP and clicking Authorize. And, that fixed it. Odd - because I
had already authorised it from the menu.

My apologies for wasted everyone's time; I have no formal training. Once
again thanks for all your responses.

Moral of the story - switch DHCP off when swapping BB routers. Many thanks.
