When you reboot SBS 2008 server, “you may experience following symptoms: SBS server will be unable to browse to Internet; Users willn’t be able to connect remotely to SBS server using utilities such as remote web workplace or Outlook web access; Client PCs that rely solely on SBS server for DNS mayn’t be able to browse Internet. If you run ipconfig on SBS 2008 server you’ll notice that default gateway is blank. If you manually assign default gateway connectivity will be restored until you reboot server. After rebooting, default gateway may again be lost. This issue occurs because of a problem with netsh utility in Windows Server 2008. In certain conditions, the netsh command improperly adds a Unicode Null character before real value for default gateway in registry. Note: Small Business Server Connect to Internet Wizard uses the netsh command to set default gateway on server,” explains Microsoft. To resolve this problem, refer Microsoft knowledge base article KB 973243.
