System Reports 'Access Denied' with Event ID 100 while FTP Access

I am working for configure a FTP server for a small size company. They are using Server 2003 for Domain and FTP Services. After Configuration of FTP Server we are getting an error to access site on client machine.

Event ID- 100,  Source - MSFTPSVC
Type - Warning

"The Server was unable to logon the Windows NT account "....\...." due to the following error: Logon failure error: unknown user name or bad password. The Data is the error code.

After testing every thing I am found that AD server is not authorized to logon in locally with Active Directory User and Group.



To resolve this issue, modify the Group Policy Object (GPO) for the domain controller to assign the Log on Locally user right to the Users group: 

1. Open The  Domain Controller Security Policy.
2. Double-click Security Settings, double-click Local Policies, and then click User Rights Assignment.
3. Under Policy, click Log on Locally, and then click Add. 
4. Click Browse, locate and click the appropriate group, and then click Add.
5. Click OK in the open dialog boxes to close them and save the new settings.

Now Update your Group Policy on Server Using following Command or Log-off and Logon Your Server System.

- "Gpupdate.exe /force"
