When running a solution where one machine runs a server and a second machine runs a client connecting via named pipes I'm having a strange issue.
If both machines run the same Microsoft account, the connection is done successfully. However, if the account is not the same, the connection fails with a "The username or password is incorrect" exception on the client side.
I already added an access rule where I gave the WorldSid full control so I do not believe it to be a permission issue. I'm however wondering if it is a limitation that I'm not aware of.
