We just had a power failure our complete region had no power. Luckely all our server were conected to an UPS therefore we could shutdown all aour servers nice and easy. After the power failure was gone we started our servers again. All of them but only one came up normally. The one server is our exchange 2000 server and our DNS. The server services Kerberos Key Distribution Center won't start, which result in a failure of the services Netlogon, DNS etc....Approximatly 20/25 services failed to start.
