Small network w/ 3 XP pro sp2 client PCs and 1 2003 SBS (stnd). Everything has been working fine (1 year) and then this morning none of the client PCs could log in to domain.  Clients unable to ping domain server. Clients can access internet. SBS can see and access folders/files the client PCs.

SBS:
1. Has 1 NIC
2. Handling both DHCP and DNS. Checked to make sure DNS was running and it is

Clients:

1. NIC configured for DHCP and DNS points to SBS IP

This sounds like DNS issue but I don't know what. Any ideas?

Thank you in advance for your input.

No problem...

Just curious, though, were you not able to use EITHER RDP or RWW to get in remotely?

Well, having the router handling DHCP is part of the problem because it's not passing the correct settings to your clients.  Because somehow it's giving your clients that wp.comcast.net DNS Search Suffix... not a good thing if you want them to work right.  You're also missing a WINS server entry.

So, first you should add a WINS server entry on your Server's NIC for 192.168.10.5.

Then, disable DHCP on the router, and install and authorize DHCP on your SBS.  
For more information about installing the DHCP Server service, click Start, click Help and Support, and then search for the topic "To install a DHCP server."

Finally, you must run the Configure Email and Internet Connection Wizard (CEICW -- which is linked as Connect to the Internet in the Server Management Console > Internet and Email) to configure the scope properly.

A visual how-to is here:  http://sbsurl.com/ceicw and a full networking overview for SBS is at http://sbsurl.com/msicw

Within that wizard you'll see a "more information" button on each screen that has invaluable help in deciding which options to select.  
Be sure to check those out as well.

You can then reboot your workstations so that they will get the proper settings.  My guess is that this whole thing may have been caused by a change in the way Comcast pushes through their DNS, but by using your SBS for DHCP you'll avoid any such problems.

try 2 things
first go to command prompt.
type     net stop ipnat
now try to ping server from client.

If that dosent work try running the internet connection wizard again and leave the settings the same.

hope that helps.
Im guessing you fixed the problem, how bout a response.

I'm sorry for the delay. I had emergency surgery on the 10th and just returned home on Wednesday. I haven't dealt w/ the problem since then and won't until probably this weekend or into next week.

Thanks
