When we try to make backup selections with Backup Exec in Windows 2008R2 we receive a message with error that says: Failed to log on to Microsoft Windows. The OS is Windows 2008R2 SP1 and the App is Symantec Backup Exec 2012 SP1 This problema started with one or two clients from the begining of the installation and continue with the others in the las days, we have 3 weeks with the servers installed. We enabled the debug log of Backup Exec 2012 to review why is this happening and faund the next log: [10496] 2012-07-13T11:46:31.751 [ndmp\ndmpcomm] - Could not resolve the "bews-ndmp" or the "ndmp" service, error code: 10109, using port 10000 [10496] 2012-07-13T11:46:31.752 [ndmp\ndmpcomm] - ndmpConnectEx: 'SERVER NAME' resolves to the local machine itself.

Looking what these errors means I found this with NET HELMSG in DOS window: People from support of Symantec says this problema is whith Windows and they could not do anything. Some body else have been Works with problem?

[10752] 2012-07-13T11:46:32.090 | LogonUser failed: Logon failure: the user has not been granted the requested logon type at this computer. Are you sure the account is a local admin on the server? The erromessages indicate a connectivity issue. See what happens when you try to connect to the server from the backup server witha standard \\server\c$ command. My Knee Jerk Reaction.BlankMonkey

The server access without problem by windows explorer, the issue only is presented with the application, people from Symantec detected the error number and discard the Application as the problem, they suggested the OS has a BUG and we need assistant from Microsoft. This problem started with the acces to one of eight client servers, and continue growing up today with 6 servers with problems. Thank you!Microsoft TechNet Forums

This is an application problem not related to windows Servers.

Sorry to say this but Symantec Support always does this kind of job, that is passing ball on the others court. You better escalate this with Symantec again.Don't be a prick !
