- Users receive the following error when logging onto a domain-joined Windows Vista or Windows 7 computer using cached credentials:
There are currently no logon servers available to service the logon request.
- LsaSrv Event 45058, logged in the System event log of a domain-joined workstation, indicates that the operating system has deleted the cached credential for the user specified in the event:
Log Name: System
Date: <date> <time>
Event ID: 45058
Task Category: Logon Cache
A logon cache entry for user USERNAME@CONTOSO.COM was the oldest entry and was removed. The timestamp of this entry was MM/DD/YYYY HH:MM:SS.
The user logon error occurs when a user's cached credentials have been purged from the local computer by more recent domain user logons.
Windows Vista and Windows 7 operating systems cache credentials for a finite number of user accounts (assuming cached credentials have not been disabled).
Once the cached logon quota has been reached, the operating system will purge the oldest cached credential from the local computer so that the credentials for the next unique domain user successfully authenticated by a domain controller may be cached. The logging of the LsaSrv 45058 event indicates that the cached logon quota has been reached, triggering the deletion of the oldest user credential cached on the local machine.
- Verify that cache credentials are allowed on the local computer
If the CachedLogonsCount registry value is 0 then the system will not cache domain user credentials. See the More Information section below to determine the configurable range.
If the user's credentials have been deleted OR cached credentials are disabled, establish network connectivity and name resolution with one or more domain controllers that can authenticate the user account's domain logon (VPN, etc.), then successfully authenticate the user's logon.
If cached logons are enabled, a successful logon will cache that user's credentials while purging the oldest cached credentials.
If establishing domain connectivity over a software VPN, you'll likely have to establish the VPN from another local or cached domain user, persist that connection while logging off, then logging on or switching to the domain user account whose credentials you want to cache.
Evaluate increasing the cache logon quota with a domain administrator.
The number of "slots" available to store credentials is controlled by:
Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Setting Name: CachedLogonsCount
Data Type: REG_SZ
Value: Default value = 10 decimal, max value = 50 decimal, minimum value = 1
Cached credentials can also be managed with group policy by configuring:
Group Policy Setting path: Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\Security Options.
Group Policy Setting: Interactive logon: Number of previous logons to cache (in case domain controller is not available)
The workstation the user needs access to must have physical connectivity with the domain and the user must authenticate with a domain controller to cache their credentials again.
