  3. In the details pane, click New, and then click DWORD (32-bit) Value.
  4. Type DisabledComponents, and then press ENTER.
  5. Double-click DisabledComponents, and then type 0xffffffff in Hexadecimal or 4294967295 in Decimal.Note The 0xffffffff value or the 4294967295 value disables all IPv6 components except for the IPv6 loopback interface.

Yesterday, while working with one of the SBS 2008 server, after reboot my exchange services were not able to start and was getting stuck in starting mode. Spent lot of time and went through lot of forums and lastly i found that, it was because i disabled IPV6. So folks, if you find your exchange all of sudden behaving abnormally in SBS 2008, it may be because of IPV6.
