P2V

Hi Microsoft GP Gurus,

Currently converted Physical servers to virtual via Disk2vhd. Servers works fine, except Microsoft Dynamics GP login wont work anymore.

We use Microsoft Dynamics GP 2010.

When try to login :

"Your attempt to log in to the server failed because an unknown error occurred when the user ID and password were being verified. Attempt to login again."

I take your virtual server names are different from their physical counterparts. If this is correct, the only account that should be able to login is sa.

Microsoft Dynamics GP password encryption algorithm uses the server name as part of the encryption. Change the server name and the passwords will no longer be valid.

Two ways to fix this:

1. You can drop all SQL accounts and database users, along with removing all GP users. Then you would recreate them and assign them to their companies and security roles. This would setup the SQL accounts once more and create the proper database user. The issue here is, it's a time consuming operation.

2. You can capture the users and passwords by using the Capture Logins script in KB article 878449 - support.microsoft.com/.../how-to-transfer-an-existing-microsoft-dynamics-gp-microsoft-small-busi

Hope this helps,
