Recently we have been seeing two different issues on SBS servers that can be caused by the 3 rd party product Symantec Endpoint Protection 11.0 . Please note that these issues can also be caused by other factors.
Issue 1: DHCP
SBS client machines are unable to receive an IP address lease from a DHCP running on the SBS server. Statically assigning an IP address to the client machine allows it to function normally on the network.
Issue 2: Access to Shares
Client machines lose connectivity to shares hosted on the SBS 2003 server after a period of time. Rebooting the SBS server is the only way in which you are able to restore the connectivity.
These issues have been documented in the following Symantec FAQ:

The following Symantec Knowledge Base article offers a resolution for the “inaccessible shares” issue. However, the article does not state that it resolves the inability to obtain an IP address lease by SBS client machines.

Please contact Symantec for further information on these issues.
