The following error appears when trying to log in to Network Atlas on the primary Orion server:

An unexpected error occurred - call support


The following error also appears in the SolarWinds.Orion.Web.AuthorizationManager file:
(null) Get Auth Groups of scyr in WRBTS. System.DirectoryServices.AccountManagement.PrincipalOperationException: An error (1301) occurred while enumerating the groups. The group's SID could not be resolved.

at SolarWinds.Orion.Web.AuthorizationManager.WindowsAuthorizationManager.GetPrincipalGroups(WindowsIdentity identity, String identName,

PrincipalContext context, String domainName, Boolean& faulted)


All Orion products with Network Atlas


This can occur because of the following:

  • The account being used by the application pool is not a member of the local administrator or domain administrator groups.
  • The security identifiers (SIDs) S-1-18-1 and S-1-18-2 cannot be mapped after a Windows 2012 domain controller is added to the network.


  1. Open a command prompt on the main poller.
  2. Run the following command:
    psgetsid S-1-18-1
    Note: The following error may appear:
    Error querying SID: No mapping between account names and security IDs was done.
    This specific error mapping the SIDs is limited to Windows 7 and Windows 2008 R2.

3.  Log in to the server with an account that has the correct administrative permissions. If this has already been done and psgetsid fails with the error above, refer to the Microsoft KB Article 2830145.
