and the System event log on that server contains:

Event Id 7000 - The NetBEUI Protocol failed to start due to the following error: The system cannot find the file specified.
Event Id 7001 - The Remote Access Service depends on the NetBEUI protocol service which failed to start because of the following error: The system cannot find the file specified.

Remove the NetBEUI protocol (Control Panel / Network), reboot, and reinstall it.

Don't forget to reapply your latest service pack.
