Hello @Santhosh Kumar S ,

Welcome to the Microsoft Q&A platform.

        DataLakeServiceClient serviceClient = new DataLakeServiceClient(serviceUri, sharedKeyCredential);  
        DataLakeFileSystemClient filesystem = serviceClient.GetFileSystemClient("container");  
        DataLakeDirectoryClient directoryClient = filesystem.GetDirectoryClient("test");  
        DataLakeFileClient fileClient = directoryClient.GetFileClient("File11.json");  
        fileClient.Rename("test/def.json");  

I tried a similar snippet at my end and was not able to observe the issue at my end.

Upon further checking - the error could be related to windows-sockets-error.

Reference : https://learn.microsoft.com/en-us/windows/win32/winsock/windows-sockets-error-codes-2?redirectedfrom=MSDN#WSANO_DATA

This hints at some DNS issue - DNS resolution issue. Possible that you re in VNET - Org network that prevents access to the Azure endpoint.

I'd check whether the issue is replicable across network.

Hope this will help. Please let us know if any further queries.
