About Windows Accounts
The following table describes the various Windows user accounts. Windows service accounts allow system administrators to control the permission level that is granted to a Windows service. Windows services that access network resources might require a restart when the associated user account password is changed.
Windows account types
Who can change the password?
Local user
Local user
Local administrator account
An account with local system privileges on a Windows system that a user accesses.
Domain user
Domain user
Domain administrator
A network-based user account. Domain user accounts provide users with access to network resources. A domain user account is authenticated against Active Directory.
Local administrator
Local administrator
A local administrator account has administrator privileges on the local system, but does not have Network Administrator privileges. A local administrator cannot change domain user account passwords.
Domain administrator
Domain administrator
A domain administrator account has administrator privileges throughout the domain. A domain administrator requires local administrator privileges to update local accounts.
By default, when a system joins the domain, the domain administrator is given local administrator access.
Windows Proxy Configuration
The configuration of the Windows Proxy depends on the type of accounts you are managing and whether your network is part of a domain.
You can install as many Windows Proxies as you need. You must install a minimum of one Windows Proxy for each domain or workgroup. The Windows Proxy service must run as a domain administrator or local administrator. By default, the Windows Proxy installs with local service permissions. You must update the local service permissions to manage passwords over a network connection.
The following table lists the target host and target account registration notes associated with the various Windows Proxy installation options.
Windows Proxy service runs as:
Target user account type
Target host configuration notes
Target Account Registration notes
Domain administrator
The domain administrator must have local administrator privileges on the target host.
When adding the target account, select the option Use Proxy credentials to change password.
Domain administrator
(target host)
The account being managed (on the target host) must have Log in local user rights.
When adding the target account, the account that is selected to manage passwords must have Local Administrator privileges.
Local administrator
(Proxy host)
Not recommended
Not recommended
Local administrator
(Proxy host)
(target host)
When adding the target account, the account that is selected to manage passwords must have local administrator privileges.
Privileged Access Manager
 manages the administrator account that the Windows Proxy service runs as, do 
 configure this account to change its own password. The Windows service cannot restart itself after a password change. Instead, use a second Windows Proxy running as a different account to manage the service account. Use a separate target application that only uses the remote proxy. When you configure the Windows target account for the Windows Proxy, discover the proxy service and set the 
 option. This option allows 
Privileged Access Manager
 to restart the service on a password change.
The accounts that are associated with the two Windows Proxy services must be in the Administrators group on their proxy hosts. The proxies can then manage other accounts on either host, or on remote hosts with target applications that have selected both proxies for high availability.
When verifying the passwords of Windows Proxy target applications, Credential Manager connects to target servers using the Windows Proxy.
When adding a domain controller target server, use the domain controller NetBIOS name as the target server host name.
You can register the Windows Proxies in Credential Manager manually or automatically. Upon receipt of the Windows Proxy login, the server automatically adds the Windows Proxy in an inactive state and flags the request in the UI.
A Windows Proxy is not configured as a managed object device, so the proxy does not appear in the Device list. However, this same host can still be the target of a 
Privileged Access Manager
 managed object.  The same host can be used for access or password management as a device. 
When the 
Privileged Access Manager
 server sends sensitive information to a Windows Proxy, that information is encrypted using the Windows Proxy key. The key is unique for each Windows Proxy. The UI provides a button to update the Windows Proxy key.
Windows Proxy Requirements
This section details the hardware and software requirements for the Windows Proxy.
Hardware Requirements
The Windows Proxy requires 128 MB of RAM and 180 MB of hard drive space. The Windows Proxy log file requires 50 MB.
Operating System Requirements
The following table details the supported platforms and their associated requirements for the Windows Proxy.
Windows Proxy Platform Operating System
Minimum Patch Level
Windows 7
Windows Server 2008 R2
Windows 8.1
Any level
Windows Server 2012 R2
Any level
Windows 10
Any level
Windows Server 2016
Any level
Installing more than one Windows Proxy on the same host is not supported. Installing into the same directory overwrites the Windows Proxy already installed in that directory. Always uninstall an existing Windows Proxy before installing a newer version.
Prepare for Windows Proxy Installation
Complete the following tasks to prepare to install thge Windows Proxy:
  • Verify that firewalls do not block necessary communication ports. See Default Ports for Credential Manager
  • Verify that DNS resolution of the Windows Proxy host succeeds on the 
    Privileged Access Manager
     server. If DNS resolution of the server fails on the Windows Proxy host, the Windows Proxy hosts file (
    ) requires an entry for the server. 
  • Verify that DNS resolution of the 
    Privileged Access Manager
     server succeeds on the Windows Proxy host.
  • Disable Windows Simple File Sharing on all Windows servers that have accounts being managed through the Windows Proxy.
    Follow these steps:
    1. Select 
    2. Select 
      My Computer
    3. Select 
      , depending upon your Windows version.
    4. Select 
      Folder and Search Options
      , depending upon your Windows version.
    5. Select the 
    6. At the bottom of 
      Advanced Settings
      , disable 
      Use Sharing Wizard (Recommended)
    If you enable the sharing wizard, the Windows Proxy cannot synchronize and update accounts, and the Windows Proxy error log returns a 1326-ERROR_LOGON_FAILURE message.
  • If the Guest account in the domain or on the target server is enabled, the Windows Proxy Connector appears to verify the password. However, that target account password does not exist on the target server. Disable the guest account in the domain or on the target server to avoid this false password verification.
You can install the Windows Proxy and an A2A Client on the same Windows host. Do not use the same installation folder for both the Windows Proxy and the A2A Client. The installation of either component overwrites the Credential Manager component that is already installed in that folder.
The default values for Network Security on Windows systems allow Windows Proxy to function. If certain settings are set too restrictively, the Windows Proxy can fail.  Verify these settings in the Group or Local Policy Security Options:
    Network security: Restrict NTLM: Incoming NTLM traffic 
    Allow all
    , or 
    Not Defined
    Network security: Restrict NTLM: NTLM authentication in this domain 
    Not Defined
    , or 
    Deny for domain accounts
