You see the error message "There are currently no logon servers available to service the logon request" on the screen when:
If there is more than one domain available within a network, reset the trust relationship between the domains by executing the following command in any of the domain controller machines:
netdom trust /d:Domain1 Domain2 /Ud:Domain1\Username /reset
The /reset parameter synchronizes the appropriately shared secrets if they are not already synchronized.
Keywords: no logon servers available, trust relationship.
