Environment

Patch Manager 2.1.1.2005-SR2 and earlier

Resolution

Error displays in the local console after installing the application

If this error displays in the Patch Manager Admin Console after the initial installation, verify the following: 
  • The EminentWare DataGrid Service is running.
  • The Remote SQL database and SQL Browser services are running.
  • You are logged in to the server using the local Administrator account or a domain account that is a member of the Administrators group on the server. 

Error displays in a remote console

In this situation, the remote Patch Manager Admin Console cannot connect to the Patch Manager server to initiate console activities, such as downloading the certificate, authenticating your login, or validating security role membership. This issue prevents the EminentWare DataGrid Service from starting and running on the server.

If the error displays in the remote console, verify the following: 
  • The EminentWare DataGrid Service and the Extension Pack are running on the Patch Manager server and you can connect from the console installed on the server.
  • The host firewall on the Patch Manager server is not blocking inbound access on port 4092, which connects the console to the server.
    The installer automatically creates and enables a rule in the Windows Firewall for this communications link. If you are running a third-party host firewall or have Group Policies imposing configuration rules on the Windows Firewall, the configuration created by the installer may not be functional.
  • If the console and server are on different networks, verify if an intervening proxy server, web appliance, or other network device is blocking port 4092.
  • The network connection between the remote console and port 4092 on the server is not blocked by a network device or a network issue.
  • The Patch Manager server hostname is correct in the console logon dialog box and your local machine is properly resolving the IP Address of the server hostname.
  • If the Patch Manager Admin Console can establish a connection to the server, Patch Manager downloads an authentication certificate from the server. Do not refuse this certificate.
  • Your login has Administrator rights on the Patch Manager server. If you are using a non-admin account, configure the Security Roles from the server-side console to grant access to non-admin accounts.
