Hi,

I have configured and am using the ANSYS RSM (ARC) system.

However, there is a problem with storing the credentials of the nodes on the master computer.

Saving the password using 'arccredentials -a node1\administrator' on the master computer works normally for a certain period of time (several hours).

However, after a certain amount of time, errors related to the credentials between the master and the node occur.

The following is a log when an error occurs.

 

472    2023-04-13 AM 10:24:04    Info                Error: System.Security.SecurityException: Error trying to login as master\Administrator on node1: Username or password is incorrect
473    2023-04-13 AM 10:24:04       Location: Ansys.Rsm.Utilities.Logon.WindowsLogon.LogonUser(String user, String domain, SecureStringWrapper password, LogonType type, LogonProvider provider, Boolean doRetry)

476    2023-04-13 AM 10:24:04       Location: Ansys.Rsm.Arc.Node.NodeHandler.TryLoginAndStartWindowsProcess(ILaunchProcess processData, PasswordEntry credentials, Tuple`2 applicationAndArguments, Boolean quoteArguments, JobKillHandle stopHandle, CommandLineCommand& command, IExternalOperationResults& externalOperationResults)

 

Also, when an error occurs, storing the credentials of one node using the 'arccredentials' command will make the other nodes work properly as well.

How can i solve this problem?

Thank you.

verify that Active Directory in use or central authentication so same credentials can access all resources.
