function Set-DbaCmConnection { <# .SYNOPSIS Configures a connection object for use in remote computer management. .DESCRIPTION Configures a connection object for use in remote computer management. This function will either create new records for computers that have no connection registered so far, or it will configure existing connections if already present. As such it can be handy in making bulk-edits on connections or manually adjusting some settings. .PARAMETER ComputerName The computer to build the connection object for. .PARAMETER Credential The credential to register. .PARAMETER UseWindowsCredentials Whether using the default windows credentials is legit. Not setting this will not exclude using windows credentials, but only not pre-confirm them as working. .PARAMETER OverrideExplicitCredential Setting this will enable the credential override. The override will cause the system to ignore explicitly specified credentials, so long as known, good credentials are available. .PARAMETER OverrideConnectionPolicy Setting this will configure the connection policy override. By default, global configurations enforce, which connection type is available at all and which is disabled. .PARAMETER DisabledConnectionTypes Exlicitly disable connection types. These types will then not be used for connecting to the computer. .PARAMETER DisableBadCredentialCache Will prevent the caching of credentials if set to true. .PARAMETER DisableCimPersistence Will prevent Cim-Sessions to be reused. .PARAMETER DisableCredentialAutoRegister Will prevent working credentials from being automatically cached .PARAMETER EnableCredentialFailover Will enable automatic failing over to known to work credentials, when using bad credentials. By default, passing bad credentials will cause the Computer Management functions to interrupt with a warning (Or exception if in silent mode). .PARAMETER WindowsCredentialsAreBad Will prevent the windows credentials of the currently logged on user from being used for the remote connection. .PARAMETER CimWinRMOptions Specify a set of options to use when connecting to the target computer using CIM over WinRM. Use 'New-CimSessionOption' to create such an object. .PARAMETER CimDCOMOptions Specify a set of options to use when connecting to the target computer using CIM over DCOM. Use 'New-CimSessionOption' to create such an object. .PARAMETER AddBadCredential Adds credentials to the bad credential cache. These credentials will not be used when connecting to the target remote computer. .PARAMETER RemoveBadCredential Removes credentials from the bad credential cache. .PARAMETER ClearBadCredential Clears the cache of credentials that didn't worked. Will be applied before adding entries to the credential cache. .PARAMETER ClearCredential Clears the cache of credentials that worked. Will be applied before adding entries to the credential cache. .PARAMETER ResetCredential Resets all credential-related caches: - Clears bad credential cache - Removes last working credential - Un-Confirms the windows credentials as working - Un-Confirms the windows credentials as not working Automatically implies the parameters -ClearCredential and -ClearBadCredential. Using them together is redundant. Will be applied before adding entries to the credential cache. .PARAMETER ResetConnectionStatus Restores all connection stati to default, as if no connection protocol had ever been tested. .PARAMETER ResetConfiguration Restores the configuration back to system default. Configuration elements are the basic behavior controlling settings, such as whether to cache bad credentials, etc. These can be configured globally using the dbatools configuration system and overridden locally on a per-connection basis. For a list of all available settings, use "Get-DbatoolsConfig -Module ComputerManagement". .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Author: Fred Winmann (@FredWeinmann) Tags: ComputerManagement, CIM Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/set-DbaCmConnection .EXAMPLE Get-DbaCmConnection sql2014 | Set-DbaCmConnection -ClearBadCredential -UseWindowsCredentials Retrieves the already existing connection to sql2014, removes the list of not working credentials and configures it to default to the credentials of the logged on user. .EXAMPLE Get-DbaCmConnection | Set-DbaCmConnection -RemoveBadCredential $cred Removes the credentials stored in $cred from all connections' list of "known to not work" credentials. Handy to update changes in privilege. .EXAMPLE Get-DbaCmConnection | Export-Clixml .\connections.xml Import-Clixml .\connections.xml | Set-DbaCmConnection -ResetConfiguration At first, the current cached connections are stored in an xml file. At a later time - possibly in the profile when starting the console again - those connections are imported again and applied again to the connection cache. In this example, the configuration settings will also be reset, since after reimport those will be set to explicit, rather than deriving them from the global settings. In many cases, using the default settings is desirable. For specific settings, use New-DbaCmConnection as part of the profile in order to explicitly configure a connection. #> [CmdletBinding(DefaultParameterSetName = 'Credential')] param (
