Database Connection Error: failed OpenConnection for PC servers

Database Connection Error: failed OpenConnection: Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

 

When i do a "Check System" in labmanagement under the tab Performance Center i get the above error for both our PC servers.

 

In ALM, when i try to open an uploaded vuGen script i get the following error:

 

Problem encoutered when application tried to connect to data base: failed OpenConnection: Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

 

Does anyone know how to fix?
