After the install of SP1 on our routing and remote access box, all inter-device routing died. You can ping and traceroute within the same network, but as soon as the server has to route the packet between interfaces it just drops it. Oddly pings happily leave the network (routed correctly), but the replies get lost. They can be seen by network monitor coming back on the vpn connection, but they never make it to the lan connection. (Uninstalling SP1 fixed this issue, we have routing back).
Aditionally today we have an issue with the Fax server:
Fax Service failed to initialize because it could not initialize the TAPI devices.
Verify that a fax device is installed and configured correctly.
Win32 error code: 31.
This error code indicates the cause of the error.
If you uninstall the fax service, it’s impossible to re-install it due to this error. If anybody has any ideas, please leave them as comments.
