From: PJG51 on 9 Aug 2010 16:08 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.

From: Brian Cryer on 10 Aug 2010 05:24 Please (as already requested by Larry) do ipconfig /all and post the results back. That should also show where your clients are getting their IP addresses from. It will also show what DNS servers are being used - which for clients should be the IP address of your server. Also, if you run the DHCP manager, does it show DHCP running? -- Brian Cryer http://www.cryer.co.uk/brian "GoldStar" <balluboy(a)yahoo.com> wrote in message news:BF6CBB25-10EF-419D-AFD5-B64061782044(a)microsoft.com... > 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. > > "Kerry Brown" <kerry(a)kdbNOSPAMsys-tems.c*a*m> wrote in message > news:OOYUDR1NLHA.892(a)TK2MSFTNGP04.phx.gbl... >> 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.

From: GoldStar on 10 Aug 2010 09:43 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.

What would be useful to know is: ipconfig /all on one of the workstations - one where you are experiencing the problems. At the very least, IP address, subnet mask, default gateway, DNS servers and DHCP Server settings. I would expect to see: subnet mask of 255.255.255.0 on clients. DNS server (on clients): 192.168.1.100 (i.e. your server) Default gateway: IP address of router. Assuming your DHCP server is running then what IP address are the clients getting? If a workstation has a unique IP address and is on the same subnet, and ping times out then (i.) check that the firewall on the server is set to allow ICMP echo requests (i.e. pings) and (ii.) that there is a physical connection - so everything is plugged in, router is working, lights are on (and flashing) at all the network points. Hope you get to the bottom o fit. -- Brian Cryer http://www.cryer.co.uk/brian "GoldStar" <balluboy(a)yahoo.com> wrote in message news:6FDC7D50-BC3C-4F3E-B829-6985A8E5D863(a)microsoft.com... > 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. > > "Brian Cryer" <not.here(a)localhost> wrote in message > news:uVDMH3GOLHA.3732(a)TK2MSFTNGP02.phx.gbl... >> Please (as already requested by Larry) do >> ipconfig /all >> and post the results back.
