Can not ping WIndows 2003 SBS from workstation!!!! Help!

I have a client that is running Win SBS 2003. The problem started with their Exchange email not working, network access OK. Restarted Exchange store and rebooted. Noticed that the C: drive was full and freed up space. Now email still does not work and the server can ping (and access shares) the workstations by IP and name, but WS can't ping the server by IP or name.

Note: we can not get the Backup Exec backup devices service to start. Not sure if that would matter. I don't see how. Clients are Windows 7 Pro .

To add insult to injury, the DSL modem crapped out while troubleshooting!

Here are the troubleshooting steps we have taken so far:

1. hooked a 5 port switch bypassing current switch from to server and a workstation - same results
2. hard coded IP address on WS
3. Disabled AV (and services) on server
4. Firewall is off
5. server can ping itself including 127.0.0.1
6. created and deleted files on WS shares
7. Checked DNS logs of server, nothing stood out

I would check the event log to see if you are getting any IPSEC errors. If this is the case follow the link to the MS knowledge base to resolve this. Typically it recommends disabling the IPEC service. You will have to make a judgement call whether you need this service or not. Many problems occur once the C: runs out of space on SBS 2003, its best to resize the partition before it becomes critical using 3rd party software. Watch out for your CALS disappearing too!!

Ping and traceroute are good tools for isolating connectivity problems, but are often misused to troubleshoot other network related issues.
Start with an ipconfig /all from the server and one workstation. use nslookup to verify DNS functionality.

you cannot ping the server by ip address?

Normally I would say disable any AV/firewall you have, but you stated you have already done this.

Try booting the server up in safe mode with networking support and see if the workstation can ping the server.

Do you have any other network devices you can try and ping from the server and workstation?  Like a network printer or replacement router?

Also, as C drive ran out of space, check your licensing in the server management screen.

I've seen this a few times before when the CAL packs previously entered have disappeared because C drive was full.

Probably not related to your ping problem though.

In an SBS domain the server should be your DHCP server, assuming this is the case when the PC's are rebooted are they assigned an IP?

Could you post the results of ipconfig /all from the server. Simpler than asking how many nic's, config, and DNS.

How many NIC's do you have ?
If 2 - disable 1 which is *not* in the same subnet as LAN workstations.

Hopefully only one. SBS 2008 only supports 1 NIC.

Rob @ I have seen some interesting RRAS attempts with SBS @ EE here :) - 2 NIC's.

Breaks everything else.

Do email signature updates give you a headache?

>>"Oh there server is handing out DHCP. "
But is it working? i.e. are client machine addresses being assigned?
Just trying to determin if it is specific services that are not working or all. Where the PC's can be pinged from the server, I assumed DHCP must be working.

SBS 2003 supports 1 & 2 NIC configurations. If ISA is installed you have to have 2 NIC's. If using RRAS there are security advantages of using 2 NIC's, but SBS 2008 does not support more than 1 NIC and will 'break' some networking features if a second is installed.

Sorry everyone for the delay. The client wants to spec a new server, since the time spent troubleshooting is getting expensive. The server is 5 years old. We tried everything you all suggested but nothing seemed to work. Checked the ipconfig /all on the workstations and it pointed to the server, but can't ping. We are baffled and defeated! Thanks for your suggestion and time,
