# System Identity Changer and system user issues

This section provides information for troubleshooting issues related to the System Identity Changer utility and the system user.

In this topic:

## Error running the System Identity Changer utility

Problem Description

When running IdentityChangerUtil.exe, you receive the following error: “Another instance is already running. Please switch to it.”

This is because there is another instance of the System Identity Changer utility already running.

Troubleshooting

- If you can see the other instance, use that one, or close it and then restart the utility.

- If you cannot see the other instance of the utility, it means that another user is running it on the same machine. Switch to the other user and close the utility before attempting to run it with a different username.

## Error changing the system user

The following are possible error messages you could encounter when trying to change the system user.

Error Message | Description | Troubleshooting
--- | --- | ---
Can’t apply changes. Not all hosts are in idle state. | You receive this error because one or more of the hosts is currently busy with another operation. | Sign in to Administration and go to the Hosts module. Verify that all hosts are in the Idle state. If all of the hosts are in the Idle state, make sure that any other hosts that belong to the host pool are not idle. Open the System Identity Changer utility again. For details, see System Identity Changer Utility.
Make sure that you have entered a different username. | You receive this error because you are trying to change the user to the current username. | Choose a different username.
Configuration failed: Failed to find the Load Testing Service on <machine name>. Please verify that the service exists and that it is running. | This error might appear because the OpenText Performance Engineering Load Testing Service isn’t running, or because the SSO key is defined on the host. | Select Start > Run and enter `services.msc`. In the Services window, verify that the OpenText Performance Engineering Load Testing Service is running. Check that the SSO key which is defined on the host matches the SSO key defined on the server. You can check the SSO key in the following locations: On the server: <Server_installdir>\dat\PCS.config On the host: <Host_installdir>\dat\LTS.config If the keys do not match, change the key in LTS.config file on the host. Then open the Services window and restart the OpenText Performance Engineering Load Testing Service.
One of the following error messages appears: Problem adding required policies Problem adding user to group Problem changing application pool identity Problem changing COM settings Problem changing IIS Problem changing password Problem changing PC Group Problem creating group Problem creating user Problem deleting old identity Problem removing user from Admin | You probably receive this error because the configuration user you provided does not have the required permissions to perform the requested operation. | Supply a configuration user which has administrator permissions on all the machines on which you are trying to change the user.

## Denied access to the internal Influx database server

Problem Description

If you uninstall a host and reinstall it again, and during this time the system user name or password is changed, access to the internal Influx database on the host is denied.

This is because Influx stores its data in a folder that also includes the data of the previous authentication user. By default, the folder is under <Host_installdir>\orchidtmp\influxdb.

Troubleshooting

You must delete the folder where the Influx stores its data to reconfigure the database with the new user.
