here is  the error I am recieving

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server %1. The target name used was %3. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (%2), and the client realm. Please contact your system administrator.

Nothing changed?  Is this the same server that you just recently restored after it crashed last week?

No it's not. This one is in a different location. The one I crashed last week, is having so many glitches, I am wipeing it down over the weekend , and reloading the software. This one has been humming right along, and all of a sudden I am getting the Keberos error

Just wanted to make sure.  :-)

The most common reason for Kerberos Errors is Windows Time Synchronization.  The client workstations might have a problem with this if they were never added to the network correctly using http://<servername>/connectcomputer.  If this is the case you must do the following:

The following needs to be done with the client machine:
1.  Log in with THAT machine's LOCAL administrator account.
2.  Unjoin the domain into a WORKGROUP
3.  Change the name of the computer
4.  Delete or rename the following directory C:\Program Files\Microsoft Windows Small Business Server\Clients if it exists
5.  Make sure that the network settings are configured to get an IP address automatically (DHCP enabled)
6.  Reboot

Then on the server, from the Server Management Console:
1.  Remove the client computers if it still shows in the Client Computer screen on the Server Management Console
2.  Add the client with it's NEW name using the Add Computer wizard

Then, go back to the client machine and join the domain by opening Internet Explorer and navigating to http://servername/connectcomputer

If the workstations WERE added correctly to begin with, then you probably need tomodify the configuration of the server to be the authoritative time server of the network.

See:  http://support.microsoft.com/kb/816042 for that.
