8028 The LAN message Authentication is invalid

I use to be able to connect via Teradata .Net in Sql Assistant but now I am getting the message "8028 The LAN message Authentication is invalid".

I am still able to connect using ODBC successfully.

Any ideas of what to try for getting connecting via Teradata .Net working again?

Uninstalling everything Teradata on my computer and then reinstalling didn't help.

Hi,

I have same problem. When I try to access teradata server from saöe subnet with server, it works ok. But when subnets are different. I got same above error. For example teradata db ip : 192.168.1.10 myclient ip : 10.1.1.2 in this case, I got 8028 error. 

Additional Info : Teradata db has been updgraded from 13.0 to 13.10 Before upgrade, i was able to access from any where with .Net Provider. After upgrading 13.10, I can only access from same subnet with teradata database.

Thanks for your supports
